FTP

Since Camel 1.1

Both producer and consumer are supported

This component provides access to remote file systems over the FTP and SFTP protocols.

When consuming from remote FTP server make sure you read the section titled Default when consuming files further below for details related to consuming files.

Absolute path is not supported. Camel translates absolute path to relative by trimming all leading slashes from directoryname. There’ll be WARN message printed in the logs.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-ftp</artifactId>
    <version>x.x.x</version>See the documentation of the Apache Commons
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

ftp://[username@]hostname[:port]/directoryname[?options]
sftp://[username@]hostname[:port]/directoryname[?options]
ftps://[username@]hostname[:port]/directoryname[?options]

Where directoryname represents the underlying directory. The directory name is a relative path. Absolute path’s is not supported. The relative path can contain nested folders, such as /inbox/us.

The autoCreate option is supported. When consumer starts, before polling is scheduled, there’s additional FTP operation performed to create the directory configured for endpoint. The default value for autoCreate is true.

If no username is provided, then anonymous login is attempted using no password.
If no port number is provided, Camel will provide default values according to the protocol (ftp = 21, sftp = 22, ftps = 2222).

You can append query options to the URI in the following format, ?option=value&option=value&…

This component uses two different libraries for the actual FTP work. FTP and FTPS uses Apache Commons Net while SFTP uses JCraft JSCH.

 FTPS (also known as FTP Secure) is an extension to FTP that adds
support for the Transport Layer Security (TLS) and the Secure Sockets
Layer (SSL) cryptographic protocols.

URI Options

The options below are exclusive for the FTP component.

The FTP component supports 3 options, which are listed below.

Name	Description	Default	Type
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	boolean
basicPropertyBinding (advanced)	Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities	false	boolean

String

Query Parameters (110 parameters):

Name	Description	Default	Type
binary (common)	Specifies the file transfer mode, BINARY or ASCII. Default is ASCII (false).	false	boolean
charset (common)	This option is used to specify the encoding of the file. You can use this on the consumer, to specify the encodings of the files, which allow Camel to know the charset it should load the file content in case the file content is being accessed. Likewise when writing a file, you can use this option to specify which charset to write the file as well. Do mind that when writing the file Camel may have to read the message content into memory to be able to convert the data into the configured charset, so do not use this if you have big messages.		String
disconnect (common)	Whether or not to disconnect from remote FTP server right after use. Disconnect will only disconnect the current connection to the FTP server. If you have a consumer which you want to stop, then you need to stop the consumer/route instead.	false	boolean
doneFileName (common)	Producer: If provided, then Camel will write a 2nd done file when the original file has been written. The done file will be empty. This option configures what file name to use. Either you can specify a fixed name. Or you can use dynamic placeholders. The done file will always be written in the same folder as the original file. Consumer: If provided, Camel will only consume files if a done file exists. This option configures what file name to use. Either you can specify a fixed name. Or you can use dynamic placeholders.The done file is always expected in the same folder as the original file. Only \${file.name} and \${file.name.next} is supported as dynamic placeholders.		String
fileName (common)	Use Expression such as File Language to dynamically set the filename. For consumers, it’s used as a filename filter. For producers, it’s used to evaluate the filename to write. If an expression is set, it take precedence over the CamelFileName header. (Note: The header itself can also be an Expression). The expression options support both String and Expression types. If the expression is a String type, it is always evaluated using the File Language. If the expression is an Expression type, the specified Expression type is used - this allows you, for instance, to use OGNL expressions. For the consumer, you can use it to filter filenames, so you can for instance consume today’s file using the File Language syntax: mydata-\${date:now:yyyyMMdd}.txt. The producers support the CamelOverruleFileName header which takes precedence over any existing CamelFileName header; the CamelOverruleFileName is a header that is used only once, and makes it easier as this avoids to temporary store CamelFileName and have to restore it afterwards.		String
passiveMode (common)	Sets passive mode connections. Default is active mode connections.	false	boolean
separator (common)	Sets the path separator to be used. UNIX = Uses unix style path separator Windows = Uses windows style path separator Auto = (is default) Use existing path separator in file name. The value can be one of: UNIX, Windows, Auto	UNIX	PathSeparator
transferLoggingIntervalSeconds (common)	Configures the interval in seconds to use when logging the progress of upload and download operations that are in-flight. This is used for logging progress when operations takes longer time.	5	int
transferLoggingLevel (common)	Configure the logging level to use when logging the progress of upload and download operations. The value can be one of: TRACE, DEBUG, INFO, WARN, ERROR, OFF	DEBUG	LoggingLevel
transferLoggingVerbose (common)	Configures whether the perform verbose (fine grained) logging of the progress of upload and download operations.	false	boolean
fastExistsCheck (common)	If set this option to be true, camel-\ftp will use the list file directly to check if the file exists. Since some FTP server may not support to list the file directly, if the option is false, camel-\ftp will use the old way to list the directory and check if the file exists. This option also influences readLock=changed to control whether it performs a fast check to update file information or not. This can be used to speed up the process if the FTP server has a lot of files.	false	boolean
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
delete (consumer)	If true, the file will be deleted after it is processed successfully.	false	boolean
moveFailed (consumer)	Sets the move failure expression based on Simple language. For example, to move files into a .error subdirectory use: .error. Note: When moving the files to the fail location Camel will handle the error and will not pick up the file again.		String
noop (consumer)	If true, the file is not moved or deleted in any way. This option is good for readonly data, or for ETL type requirements. If noop=true, Camel will set idempotent=true as well, to avoid consuming the same files over and over again.	false	boolean
preMove (consumer)	Expression (such as File Language) used to dynamically set the filename when moving it before processing. For example to move in-progress files into the order directory set this value to order.		String
preSort (consumer)	When pre-sort is enabled then the consumer will sort the file and directory names during polling, that was retrieved from the file system. You may want to do this in case you need to operate on the files in a sorted order. The pre-sort is executed before the consumer starts to filter, and accept files to process by Camel. This option is default=false meaning disabled.	false	boolean
recursive (consumer)	If a directory, will look for files in all the sub-directories as well.	false	boolean
resumeDownload (consumer)	Configures whether resume download is enabled. This must be supported by the FTP server (almost all FTP servers support it). In addition the options localWorkDirectory must be configured so downloaded files are stored in a local directory, and the option binary must be enabled, which is required to support resuming of downloads.	false	boolean
sendEmptyMessageWhenIdle (consumer)	If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.	false	boolean
streamDownload (consumer)	Sets the download method to use when not using a local working directory. If set to true, the remote files are streamed to the route as they are read. When set to false, the remote files are loaded into memory before being sent into the route. If enabling this option then you must set stepwise=false as both cannot be enabled at the same time.	false	boolean
download (consumer)	Whether the FTP consumer should download the file. If this option is set to false, then the message body will be null, but the consumer will still trigger a Camel Exchange that has details about the file such as file name, file size, etc. It’s just that the file will not be downloaded.	false	boolean
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange. The value can be one of: InOnly, InOut, InOptionalOut		ExchangePattern
handleDirectoryParserAbsolute Result (consumer)	Allows you to set how the consumer will handle subfolders and files in the path if the directory parser results in with absolute paths The reason for this is that some FTP servers may return file names with absolute paths, and if so then the FTP component needs to handle this by converting the returned path into a relative path.	false	boolean
ignoreFileNotFoundOrPermission Error (consumer)	Whether to ignore when (trying to list files in directories or when downloading a file), which does not exist or due to permission error. By default when a directory or file does not exists or insufficient permission, then an exception is thrown. Setting this option to true allows to ignore that instead.	false	boolean
inProgressRepository (consumer)	A pluggable in-progress repository org.apache.camel.spi.IdempotentRepository. The in-progress repository is used to account the current in progress files being consumed. By default a memory based repository is used.		IdempotentRepository
localWorkDirectory (consumer)	When consuming, a local work directory can be used to store the remote file content directly in local files, to avoid loading the content into memory. This is beneficial, if you consume a very big remote file and thus can conserve memory.		String
onCompletionExceptionHandler (consumer)	To use a custom org.apache.camel.spi.ExceptionHandler to handle any thrown exceptions that happens during the file on completion process where the consumer does either a commit or rollback. The default implementation will log any exception at WARN level and ignore.		ExceptionHandler
pollStrategy (consumer)	A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.		PollingConsumerPollStrategy
processStrategy (consumer)	A pluggable org.apache.camel.component.file.GenericFileProcessStrategy allowing you to implement your own readLock option or similar. Can also be used when special conditions must be met before a file can be consumed, such as a special ready file exists. If this option is set then the readLock option does not apply.		GenericFileProcessStrategy
useList (consumer)	Whether to allow using LIST command when downloading a file. Default is true. In some use cases you may want to download a specific file and are not allowed to use the LIST command, and therefore you can set this option to false. Notice when using this option, then the specific file to download does not include meta-data information such as file size, timestamp, permissions etc, because those information is only possible to retrieve when LIST command is in use.	true	boolean
fileExist (producer)	What to do if a file already exists with the same name. Override, which is the default, replaces the existing file. - Append - adds content to the existing file. - Fail - throws a GenericFileOperationException, indicating that there is already an existing file. - Ignore - silently ignores the problem and does not override the existing file, but assumes everything is okay. - Move - option requires to use the moveExisting option to be configured as well. The option eagerDeleteTargetFile can be used to control what to do if an moving the file, and there exists already an existing file, otherwise causing the move operation to fail. The Move option will move any existing files, before writing the target file. - TryRename is only applicable if tempFileName option is in use. This allows to try renaming the file from the temporary name to the actual name, without doing any exists check. This check may be faster on some file systems and especially FTP servers. The value can be one of: Override, Append, Fail, Ignore, Move, TryRename	Override	GenericFileExist
flatten (producer)	Flatten is used to flatten the file name path to strip any leading paths, so it’s just the file name. This allows you to consume recursively into sub-directories, but when you eg write the files to another directory they will be written in a single directory. Setting this to true on the producer enforces that any file name in CamelFileName header will be stripped for any leading paths.	false	boolean
jailStartingDirectory (producer)	Used for jailing (restricting) writing files to the starting directory (and sub) only. This is enabled by default to not allow Camel to write files to outside directories (to be more secured out of the box). You can turn this off to allow writing files to directories outside the starting directory, such as parent or root folders.	true	boolean
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	boolean
moveExisting (producer)	Expression (such as File Language) used to compute file name to use when fileExist=Move is configured. To move files into a backup subdirectory just enter backup. This option only supports the following File Language tokens: file:name, file:name.ext, file:name.noext, file:onlyname, file:onlyname.noext, file:ext, and file:parent. Notice the file:parent is not supported by the FTP component, as the FTP component can only move any existing files to a relative directory based on current dir as base.		String
tempFileName (producer)	The same as tempPrefix option but offering a more fine grained control on the naming of the temporary filename as it uses the File Language. The location for tempFilename is relative to the final file location in the option 'fileName', not the target directory in the base uri. For example if option fileName includes a directory prefix: dir/finalFilename then tempFileName is relative to that subdirectory dir.		String
tempPrefix (producer)	This option is used to write the file using a temporary name and then, after the write is complete, rename it to the real name. Can be used to identify files being written and also avoid consumers (not using exclusive read locks) reading in progress files. Is often used by FTP when uploading big files.		String
allowNullBody (producer)	Used to specify if a null body is allowed during file writing. If set to true then an empty file will be created, when set to false, and attempting to send a null body to the file component, a GenericFileWriteException of 'Cannot write null body to file.' will be thrown. If the fileExist option is set to 'Override', then the file will be truncated, and if set to append the file will remain unchanged.	false	boolean
chmod (producer)	Allows you to set chmod on the stored file. For example chmod=640.		String
disconnectOnBatchComplete (producer)	Whether or not to disconnect from remote FTP server right after a Batch upload is complete. disconnectOnBatchComplete will only disconnect the current connection to the FTP server.	false	boolean
eagerDeleteTargetFile (producer)	Whether or not to eagerly delete any existing target file. This option only applies when you use fileExists=Override and the tempFileName option as well. You can use this to disable (set it to false) deleting the target file before the temp file is written. For example you may write big files and want the target file to exists during the temp file is being written. This ensure the target file is only deleted until the very last moment, just before the temp file is being renamed to the target filename. This option is also used to control whether to delete any existing files when fileExist=Move is enabled, and an existing file exists. If this option copyAndDeleteOnRenameFails false, then an exception will be thrown if an existing file existed, if its true, then the existing file is deleted before the move operation.	true	boolean
keepLastModified (producer)	Will keep the last modified timestamp from the source file (if any). Will use the Exchange.FILE_LAST_MODIFIED header to located the timestamp. This header can contain either a java.util.Date or long with the timestamp. If the timestamp exists and the option is enabled it will set this timestamp on the written file. Note: This option only applies to the file producer. You cannot use this option with any of the \ftp producers.	false	boolean
moveExistingFileStrategy (producer)	Strategy (Custom Strategy) used to move file with special naming token to use when fileExist=Move is configured. By default, there is an implementation used if no custom strategy is provided		FileMoveExistingStrategy
sendNoop (producer)	Whether to send a noop command as a pre-write check before uploading files to the FTP server. This is enabled by default as a validation of the connection is still valid, which allows to silently re-connect to be able to upload the file. However if this causes problems, you can turn this option off.	true	boolean
activePortRange (advanced)	Set the client side port range in active mode. The syntax is: minPort-maxPort Both port numbers are inclusive, eg 10000-19999 to include all 1xxxx ports.		String
autoCreate (advanced)	Automatically create missing directories in the file’s pathname. For the file consumer, that means creating the starting directory. For the file producer, it means the directory the files should be written to.	true	boolean
basicPropertyBinding (advanced)	Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities	false	boolean
bufferSize (advanced)	Buffer size in bytes used for writing files (or in case of FTP for downloading and uploading files).	131072	int
connectTimeout (advanced)	Sets the connect timeout for waiting for a connection to be established Used by both FTPClient and JSCH	10000	int
ftpClient (advanced)	To use a custom instance of FTPClient		FTPClient
ftpClientConfig (advanced)	To use a custom instance of FTPClientConfig to configure the FTP client the endpoint should use.		FTPClientConfig
ftpClientConfigParameters (advanced)	Used by FtpComponent to provide additional parameters for the FTPClientConfig		Map
ftpClientParameters (advanced)	Used by FtpComponent to provide additional parameters for the FTPClient		Map
maximumReconnectAttempts (advanced)	Specifies the maximum reconnect attempts Camel performs when it tries to connect to the remote FTP server. Use 0 to disable this behavior.		int
reconnectDelay (advanced)	Delay in millis Camel will wait before performing a reconnect attempt.		long
siteCommand (advanced)	Sets optional site command(s) to be executed after successful login. Multiple site commands can be separated using a new line character.		String
soTimeout (advanced)	Sets the so timeout FTP and FTPS Only for Camel 2.4. SFTP for Camel 2.14.3/2.15.3/2.16 onwards. Is the SocketOptions.SO_TIMEOUT value in millis. Recommended option is to set this to 300000 so as not have a hanged connection. On SFTP this option is set as timeout on the JSCH Session instance.	5m	int
stepwise (advanced)	Sets whether we should stepwise change directories while traversing file structures when downloading files, or as well when uploading a file to a directory. You can disable this if you for example are in a situation where you cannot change directory on the FTP server due security reasons. Stepwise cannot be used together with streamDownload.	true	boolean
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean
throwExceptionOnConnectFailed (advanced)	Should an exception be thrown if connection failed (exhausted) By default exception is not thrown and a WARN is logged. You can use this to enable exception being thrown and handle the thrown exception from the org.apache.camel.spi.PollingConsumerPollStrategy rollback method.	false	boolean
timeout (advanced)	Sets the data timeout for waiting for reply Used only by FTPClient	30s	int
antExclude (filter)	Ant style filter exclusion. If both antInclude and antExclude are used, antExclude takes precedence over antInclude. Multiple exclusions may be specified in comma-delimited format.		String
antFilterCaseSensitive (filter)	Sets case sensitive flag on ant filter.	true	boolean
antInclude (filter)	Ant style filter inclusion. Multiple inclusions may be specified in comma-delimited format.		String
eagerMaxMessagesPerPoll (filter)	Allows for controlling whether the limit from maxMessagesPerPoll is eager or not. If eager then the limit is during the scanning of files. Where as false would scan all files, and then perform sorting. Setting this option to false allows for sorting all files first, and then limit the poll. Mind that this requires a higher memory usage as all file details are in memory to perform the sorting.	true	boolean
exclude (filter)	Is used to exclude files, if filename matches the regex pattern (matching is case in-senstive). Notice if you use symbols such as plus sign and others you would need to configure this using the RAW() syntax if configuring this as an endpoint uri. See more details at configuring endpoint uris		String
filter (filter)	Pluggable filter as a org.apache.camel.component.file.GenericFileFilter class. Will skip files if filter returns false in its accept() method.		GenericFileFilter
filterDirectory (filter)	Filters the directory based on Simple language. For example to filter on current date, you can use a simple date pattern such as \${date:now:yyyMMdd}		String
filterFile (filter)	Filters the file based on Simple language. For example to filter on file size, you can use \${file:size} 5000		String
idempotent (filter)	Option to use the Idempotent Consumer EIP pattern to let Camel skip already processed files. Will by default use a memory based LRUCache that holds 1000 entries. If noop=true then idempotent will be enabled as well to avoid consuming the same files over and over again.	false	Boolean
idempotentKey (filter)	To use a custom idempotent key. By default the absolute path of the file is used. You can use the File Language, for example to use the file name and file size, you can do: idempotentKey=\${file:name}-\${file:size}		String
idempotentRepository (filter)	A pluggable repository org.apache.camel.spi.IdempotentRepository which by default use MemoryMessageIdRepository if none is specified and idempotent is true.		IdempotentRepository
include (filter)	Is used to include files, if filename matches the regex pattern (matching is case in-sensitive). Notice if you use symbols such as plus sign and others you would need to configure this using the RAW() syntax if configuring this as an endpoint uri. See more details at configuring endpoint uris		String
maxDepth (filter)	The maximum depth to traverse when recursively processing a directory.	2147483647	int
maxMessagesPerPoll (filter)	To define a maximum messages to gather per poll. By default no maximum is set. Can be used to set a limit of e.g. 1000 to avoid when starting up the server that there are thousands of files. Set a value of 0 or negative to disabled it. Notice: If this option is in use then the File and FTP components will limit before any sorting. For example if you have 100000 files and use maxMessagesPerPoll=500, then only the first 500 files will be picked up, and then sorted. You can use the eagerMaxMessagesPerPoll option and set this to false to allow to scan all files first and then sort afterwards.		int
minDepth (filter)	The minimum depth to start processing when recursively processing a directory. Using minDepth=1 means the base directory. Using minDepth=2 means the first sub directory.		int
move (filter)	Expression (such as Simple Language) used to dynamically set the filename when moving it after processing. To move files into a .done subdirectory just enter .done.		String
exclusiveReadLockStrategy (lock)	Pluggable read-lock as a org.apache.camel.component.file.GenericFileExclusiveReadLockStrategy implementation.		GenericFileExclusiveReadLockStrategy
readLock (lock)	Used by consumer, to only poll the files if it has exclusive read-lock on the file (i.e. the file is not in-progress or being written). Camel will wait until the file lock is granted. This option provides the build in strategies: - none - No read lock is in use - markerFile - Camel creates a marker file (fileName.camelLock) and then holds a lock on it. This option is not available for the FTP component - changed - Changed is using file length/modification timestamp to detect whether the file is currently being copied or not. Will at least use 1 sec to determine this, so this option cannot consume files as fast as the others, but can be more reliable as the JDK IO API cannot always determine whether a file is currently being used by another process. The option readLockCheckInterval can be used to set the check frequency. - fileLock - is for using java.nio.channels.FileLock. This option is not avail for Windows OS and the FTP component. This approach should be avoided when accessing a remote file system via a mount/share unless that file system supports distributed file locks. - rename - rename is for using a try to rename the file as a test if we can get exclusive read-lock. - idempotent - (only for file component) idempotent is for using a idempotentRepository as the read-lock. This allows to use read locks that supports clustering if the idempotent repository implementation supports that. - idempotent-changed - (only for file component) idempotent-changed is for using a idempotentRepository and changed as the combined read-lock. This allows to use read locks that supports clustering if the idempotent repository implementation supports that. - idempotent-rename - (only for file component) idempotent-rename is for using a idempotentRepository and rename as the combined read-lock. This allows to use read locks that supports clustering if the idempotent repository implementation supports that.Notice: The various read locks is not all suited to work in clustered mode, where concurrent consumers on different nodes is competing for the same files on a shared file system. The markerFile using a close to atomic operation to create the empty marker file, but its not guaranteed to work in a cluster. The fileLock may work better but then the file system need to support distributed file locks, and so on. Using the idempotent read lock can support clustering if the idempotent repository supports clustering, such as Hazelcast Component or Infinispan. The value can be one of: none, markerFile, fileLock, rename, changed, idempotent, idempotent-changed, idempotent-rename	none	String
readLockCheckInterval (lock)	Interval in millis for the read-lock, if supported by the read lock. This interval is used for sleeping between attempts to acquire the read lock. For example when using the changed read lock, you can set a higher interval period to cater for slow writes. The default of 1 sec. may be too fast if the producer is very slow writing the file. Notice: For FTP the default readLockCheckInterval is 5000. The readLockTimeout value must be higher than readLockCheckInterval, but a rule of thumb is to have a timeout that is at least 2 or more times higher than the readLockCheckInterval. This is needed to ensure that amble time is allowed for the read lock process to try to grab the lock before the timeout was hit.	1000	long
readLockDeleteOrphanLockFiles (lock)	Whether or not read lock with marker files should upon startup delete any orphan read lock files, which may have been left on the file system, if Camel was not properly shutdown (such as a JVM crash). If turning this option to false then any orphaned lock file will cause Camel to not attempt to pickup that file, this could also be due another node is concurrently reading files from the same shared directory.	true	boolean
readLockLoggingLevel (lock)	Logging level used when a read lock could not be acquired. By default a DEBUG is logged. You can change this level, for example to OFF to not have any logging. This option is only applicable for readLock of types: changed, fileLock, idempotent, idempotent-changed, idempotent-rename, rename. The value can be one of: TRACE, DEBUG, INFO, WARN, ERROR, OFF	DEBUG	LoggingLevel
readLockMarkerFile (lock)	Whether to use marker file with the changed, rename, or exclusive read lock types. By default a marker file is used as well to guard against other processes picking up the same files. This behavior can be turned off by setting this option to false. For example if you do not want to write marker files to the file systems by the Camel application.	true	boolean
readLockMinAge (lock)	This option is applied only for readLock=changed. It allows to specify a minimum age the file must be before attempting to acquire the read lock. For example use readLockMinAge=300s to require the file is at last 5 minutes old. This can speedup the changed read lock as it will only attempt to acquire files which are at least that given age.	0	long
readLockMinLength (lock)	This option is applied only for readLock=changed. It allows you to configure a minimum file length. By default Camel expects the file to contain data, and thus the default value is 1. You can set this option to zero, to allow consuming zero-length files.	1	long
readLockRemoveOnCommit (lock)	This option is applied only for readLock=idempotent. It allows to specify whether to remove the file name entry from the idempotent repository when processing the file is succeeded and a commit happens. By default the file is not removed which ensures that any race-condition do not occur so another active node may attempt to grab the file. Instead the idempotent repository may support eviction strategies that you can configure to evict the file name entry after X minutes - this ensures no problems with race conditions. See more details at the readLockIdempotentReleaseDelay option.	false	boolean
readLockRemoveOnRollback (lock)	This option is applied only for readLock=idempotent. It allows to specify whether to remove the file name entry from the idempotent repository when processing the file failed and a rollback happens. If this option is false, then the file name entry is confirmed (as if the file did a commit).	true	boolean
readLockTimeout (lock)	Optional timeout in millis for the read-lock, if supported by the read-lock. If the read-lock could not be granted and the timeout triggered, then Camel will skip the file. At next poll Camel, will try the file again, and this time maybe the read-lock could be granted. Use a value of 0 or lower to indicate forever. Currently fileLock, changed and rename support the timeout. Notice: For FTP the default readLockTimeout value is 20000 instead of 10000. The readLockTimeout value must be higher than readLockCheckInterval, but a rule of thumb is to have a timeout that is at least 2 or more times higher than the readLockCheckInterval. This is needed to ensure that amble time is allowed for the read lock process to try to grab the lock before the timeout was hit.	10000	long
backoffErrorThreshold (scheduler)	The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.		int
backoffIdleThreshold (scheduler)	The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.		int
backoffMultiplier (scheduler)	To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.		int
delay (scheduler)	Milliseconds before the next poll.	500	long
greedy (scheduler)	If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.	false	boolean
initialDelay (scheduler)	Milliseconds before the first poll starts.	1000	long
repeatCount (scheduler)	Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever.	0	long
runLoggingLevel (scheduler)	The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. The value can be one of: TRACE, DEBUG, INFO, WARN, ERROR, OFF	TRACE	LoggingLevel
scheduledExecutorService (scheduler)	Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.		ScheduledExecutorService
scheduler (scheduler)	To use a cron scheduler from either camel-spring or camel-quartz component. The value can be one of: none, spring, quartz	none	String
schedulerProperties (scheduler)	To configure additional properties when using a custom scheduler or any of the Quartz, Spring based scheduler.		Map

Name

Description

Default

Type

binary (common)

Specifies the file transfer mode, BINARY or ASCII. Default is ASCII (false).

false

boolean

charset (common)

This option is used to specify the encoding of the file. You can use this on the consumer, to specify the encodings of the files, which allow Camel to know the charset it should load the file content in case the file content is being accessed. Likewise when writing a file, you can use this option to specify which charset to write the file as well. Do mind that when writing the file Camel may have to read the message content into memory to be able to convert the data into the configured charset, so do not use this if you have big messages.

String

disconnect (common)

Whether or not to disconnect from remote FTP server right after use. Disconnect will only disconnect the current connection to the FTP server. If you have a consumer which you want to stop, then you need to stop the consumer/route instead.

false

boolean

doneFileName (common)

Producer: If provided, then Camel will write a 2nd done file when the original file has been written. The done file will be empty. This option configures what file name to use. Either you can specify a fixed name. Or you can use dynamic placeholders. The done file will always be written in the same folder as the original file. Consumer: If provided, Camel will only consume files if a done file exists. This option configures what file name to use. Either you can specify a fixed name. Or you can use dynamic placeholders.The done file is always expected in the same folder as the original file. Only \${file.name} and \${file.name.next} is supported as dynamic placeholders.

String

fileName (common)

Use Expression such as File Language to dynamically set the filename. For consumers, it’s used as a filename filter. For producers, it’s used to evaluate the filename to write. If an expression is set, it take precedence over the CamelFileName header. (Note: The header itself can also be an Expression). The expression options support both String and Expression types. If the expression is a String type, it is always evaluated using the File Language. If the expression is an Expression type, the specified Expression type is used - this allows you, for instance, to use OGNL expressions. For the consumer, you can use it to filter filenames, so you can for instance consume today’s file using the File Language syntax: mydata-\${date:now:yyyyMMdd}.txt. The producers support the CamelOverruleFileName header which takes precedence over any existing CamelFileName header; the CamelOverruleFileName is a header that is used only once, and makes it easier as this avoids to temporary store CamelFileName and have to restore it afterwards.

String

passiveMode (common)

Sets passive mode connections. Default is active mode connections.

false

boolean

separator (common)

Sets the path separator to be used. UNIX = Uses unix style path separator Windows = Uses windows style path separator Auto = (is default) Use existing path separator in file name. The value can be one of: UNIX, Windows, Auto

UNIX

PathSeparator

transferLoggingIntervalSeconds (common)

Configures the interval in seconds to use when logging the progress of upload and download operations that are in-flight. This is used for logging progress when operations takes longer time.

int

transferLoggingLevel (common)

Configure the logging level to use when logging the progress of upload and download operations. The value can be one of: TRACE, DEBUG, INFO, WARN, ERROR, OFF

DEBUG

LoggingLevel

transferLoggingVerbose (common)

Configures whether the perform verbose (fine grained) logging of the progress of upload and download operations.

false

boolean

fastExistsCheck (common)

If set this option to be true, camel-\ftp will use the list file directly to check if the file exists. Since some FTP server may not support to list the file directly, if the option is false, camel-\ftp will use the old way to list the directory and check if the file exists. This option also influences readLock=changed to control whether it performs a fast check to update file information or not. This can be used to speed up the process if the FTP server has a lot of files.

false

boolean

bridgeErrorHandler (consumer)

false

boolean

delete (consumer)

If true, the file will be deleted after it is processed successfully.

false

boolean

moveFailed (consumer)

Sets the move failure expression based on Simple language. For example, to move files into a .error subdirectory use: .error. Note: When moving the files to the fail location Camel will handle the error and will not pick up the file again.

String

noop (consumer)

If true, the file is not moved or deleted in any way. This option is good for readonly data, or for ETL type requirements. If noop=true, Camel will set idempotent=true as well, to avoid consuming the same files over and over again.

false

boolean

preMove (consumer)

Expression (such as File Language) used to dynamically set the filename when moving it before processing. For example to move in-progress files into the order directory set this value to order.

String

preSort (consumer)

When pre-sort is enabled then the consumer will sort the file and directory names during polling, that was retrieved from the file system. You may want to do this in case you need to operate on the files in a sorted order. The pre-sort is executed before the consumer starts to filter, and accept files to process by Camel. This option is default=false meaning disabled.

false

boolean

recursive (consumer)

If a directory, will look for files in all the sub-directories as well.

false

boolean

resumeDownload (consumer)

Configures whether resume download is enabled. This must be supported by the FTP server (almost all FTP servers support it). In addition the options localWorkDirectory must be configured so downloaded files are stored in a local directory, and the option binary must be enabled, which is required to support resuming of downloads.

false

boolean

sendEmptyMessageWhenIdle (consumer)

If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.

false

boolean

streamDownload (consumer)

Sets the download method to use when not using a local working directory. If set to true, the remote files are streamed to the route as they are read. When set to false, the remote files are loaded into memory before being sent into the route. If enabling this option then you must set stepwise=false as both cannot be enabled at the same time.

false

boolean

download (consumer)

Whether the FTP consumer should download the file. If this option is set to false, then the message body will be null, but the consumer will still trigger a Camel Exchange that has details about the file such as file name, file size, etc. It’s just that the file will not be downloaded.

false

boolean

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange. The value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

handleDirectoryParserAbsolute Result (consumer)

Allows you to set how the consumer will handle subfolders and files in the path if the directory parser results in with absolute paths The reason for this is that some FTP servers may return file names with absolute paths, and if so then the FTP component needs to handle this by converting the returned path into a relative path.

false

boolean

ignoreFileNotFoundOrPermission Error (consumer)

Whether to ignore when (trying to list files in directories or when downloading a file), which does not exist or due to permission error. By default when a directory or file does not exists or insufficient permission, then an exception is thrown. Setting this option to true allows to ignore that instead.

false

boolean

inProgressRepository (consumer)

A pluggable in-progress repository org.apache.camel.spi.IdempotentRepository. The in-progress repository is used to account the current in progress files being consumed. By default a memory based repository is used.

IdempotentRepository

localWorkDirectory (consumer)

When consuming, a local work directory can be used to store the remote file content directly in local files, to avoid loading the content into memory. This is beneficial, if you consume a very big remote file and thus can conserve memory.

String

onCompletionExceptionHandler (consumer)

To use a custom org.apache.camel.spi.ExceptionHandler to handle any thrown exceptions that happens during the file on completion process where the consumer does either a commit or rollback. The default implementation will log any exception at WARN level and ignore.

ExceptionHandler

pollStrategy (consumer)

A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.

PollingConsumerPollStrategy

processStrategy (consumer)

A pluggable org.apache.camel.component.file.GenericFileProcessStrategy allowing you to implement your own readLock option or similar. Can also be used when special conditions must be met before a file can be consumed, such as a special ready file exists. If this option is set then the readLock option does not apply.

GenericFileProcessStrategy

useList (consumer)

Whether to allow using LIST command when downloading a file. Default is true. In some use cases you may want to download a specific file and are not allowed to use the LIST command, and therefore you can set this option to false. Notice when using this option, then the specific file to download does not include meta-data information such as file size, timestamp, permissions etc, because those information is only possible to retrieve when LIST command is in use.

true

boolean

fileExist (producer)

What to do if a file already exists with the same name. Override, which is the default, replaces the existing file. - Append - adds content to the existing file. - Fail - throws a GenericFileOperationException, indicating that there is already an existing file. - Ignore - silently ignores the problem and does not override the existing file, but assumes everything is okay. - Move - option requires to use the moveExisting option to be configured as well. The option eagerDeleteTargetFile can be used to control what to do if an moving the file, and there exists already an existing file, otherwise causing the move operation to fail. The Move option will move any existing files, before writing the target file. - TryRename is only applicable if tempFileName option is in use. This allows to try renaming the file from the temporary name to the actual name, without doing any exists check. This check may be faster on some file systems and especially FTP servers. The value can be one of: Override, Append, Fail, Ignore, Move, TryRename

Override

GenericFileExist

flatten (producer)

Flatten is used to flatten the file name path to strip any leading paths, so it’s just the file name. This allows you to consume recursively into sub-directories, but when you eg write the files to another directory they will be written in a single directory. Setting this to true on the producer enforces that any file name in CamelFileName header will be stripped for any leading paths.

false

boolean

jailStartingDirectory (producer)

Used for jailing (restricting) writing files to the starting directory (and sub) only. This is enabled by default to not allow Camel to write files to outside directories (to be more secured out of the box). You can turn this off to allow writing files to directories outside the starting directory, such as parent or root folders.

true

boolean

lazyStartProducer (producer)

false

boolean

moveExisting (producer)

Expression (such as File Language) used to compute file name to use when fileExist=Move is configured. To move files into a backup subdirectory just enter backup. This option only supports the following File Language tokens: file:name, file:name.ext, file:name.noext, file:onlyname, file:onlyname.noext, file:ext, and file:parent. Notice the file:parent is not supported by the FTP component, as the FTP component can only move any existing files to a relative directory based on current dir as base.

String

tempFileName (producer)

The same as tempPrefix option but offering a more fine grained control on the naming of the temporary filename as it uses the File Language. The location for tempFilename is relative to the final file location in the option 'fileName', not the target directory in the base uri. For example if option fileName includes a directory prefix: dir/finalFilename then tempFileName is relative to that subdirectory dir.

String

tempPrefix (producer)

This option is used to write the file using a temporary name and then, after the write is complete, rename it to the real name. Can be used to identify files being written and also avoid consumers (not using exclusive read locks) reading in progress files. Is often used by FTP when uploading big files.

String

allowNullBody (producer)

Used to specify if a null body is allowed during file writing. If set to true then an empty file will be created, when set to false, and attempting to send a null body to the file component, a GenericFileWriteException of 'Cannot write null body to file.' will be thrown. If the fileExist option is set to 'Override', then the file will be truncated, and if set to append the file will remain unchanged.

false

boolean

chmod (producer)

Allows you to set chmod on the stored file. For example chmod=640.

String

disconnectOnBatchComplete (producer)

Whether or not to disconnect from remote FTP server right after a Batch upload is complete. disconnectOnBatchComplete will only disconnect the current connection to the FTP server.

false

boolean

eagerDeleteTargetFile (producer)

Whether or not to eagerly delete any existing target file. This option only applies when you use fileExists=Override and the tempFileName option as well. You can use this to disable (set it to false) deleting the target file before the temp file is written. For example you may write big files and want the target file to exists during the temp file is being written. This ensure the target file is only deleted until the very last moment, just before the temp file is being renamed to the target filename. This option is also used to control whether to delete any existing files when fileExist=Move is enabled, and an existing file exists. If this option copyAndDeleteOnRenameFails false, then an exception will be thrown if an existing file existed, if its true, then the existing file is deleted before the move operation.

true

boolean

keepLastModified (producer)

Will keep the last modified timestamp from the source file (if any). Will use the Exchange.FILE_LAST_MODIFIED header to located the timestamp. This header can contain either a java.util.Date or long with the timestamp. If the timestamp exists and the option is enabled it will set this timestamp on the written file. Note: This option only applies to the file producer. You cannot use this option with any of the \ftp producers.

false

boolean

moveExistingFileStrategy (producer)

Strategy (Custom Strategy) used to move file with special naming token to use when fileExist=Move is configured. By default, there is an implementation used if no custom strategy is provided

FileMoveExistingStrategy

sendNoop (producer)

Whether to send a noop command as a pre-write check before uploading files to the FTP server. This is enabled by default as a validation of the connection is still valid, which allows to silently re-connect to be able to upload the file. However if this causes problems, you can turn this option off.

true

boolean

activePortRange (advanced)

Set the client side port range in active mode. The syntax is: minPort-maxPort Both port numbers are inclusive, eg 10000-19999 to include all 1xxxx ports.

String

autoCreate (advanced)

Automatically create missing directories in the file’s pathname. For the file consumer, that means creating the starting directory. For the file producer, it means the directory the files should be written to.

true

boolean

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

soTimeout (advanced)

Sets the so timeout FTP and FTPS Only for Camel 2.4. SFTP for Camel 2.14.3/2.15.3/2.16 onwards. Is the SocketOptions.SO_TIMEOUT value in millis. Recommended option is to set this to 300000 so as not have a hanged connection. On SFTP this option is set as timeout on the JSCH Session instance.

int

stepwise (advanced)

Sets whether we should stepwise change directories while traversing file structures when downloading files, or as well when uploading a file to a directory. You can disable this if you for example are in a situation where you cannot change directory on the FTP server due security reasons. Stepwise cannot be used together with streamDownload.

true

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

throwExceptionOnConnectFailed (advanced)

Should an exception be thrown if connection failed (exhausted) By default exception is not thrown and a WARN is logged. You can use this to enable exception being thrown and handle the thrown exception from the org.apache.camel.spi.PollingConsumerPollStrategy rollback method.

false

boolean

timeout (advanced)

Sets the data timeout for waiting for reply Used only by FTPClient

30s

int

antExclude (filter)

Ant style filter exclusion. If both antInclude and antExclude are used, antExclude takes precedence over antInclude. Multiple exclusions may be specified in comma-delimited format.

String

antFilterCaseSensitive (filter)

Sets case sensitive flag on ant filter.

true

boolean

antInclude (filter)

Ant style filter inclusion. Multiple inclusions may be specified in comma-delimited format.

String

eagerMaxMessagesPerPoll (filter)

Allows for controlling whether the limit from maxMessagesPerPoll is eager or not. If eager then the limit is during the scanning of files. Where as false would scan all files, and then perform sorting. Setting this option to false allows for sorting all files first, and then limit the poll. Mind that this requires a higher memory usage as all file details are in memory to perform the sorting.

true

boolean

exclude (filter)

Is used to exclude files, if filename matches the regex pattern (matching is case in-senstive). Notice if you use symbols such as plus sign and others you would need to configure this using the RAW() syntax if configuring this as an endpoint uri. See more details at configuring endpoint uris

String

filter (filter)

Pluggable filter as a org.apache.camel.component.file.GenericFileFilter class. Will skip files if filter returns false in its accept() method.

GenericFileFilter

filterDirectory (filter)

Filters the directory based on Simple language. For example to filter on current date, you can use a simple date pattern such as \${date:now:yyyMMdd}

String

filterFile (filter)

Filters the file based on Simple language. For example to filter on file size, you can use \${file:size} 5000

String

idempotent (filter)

Option to use the Idempotent Consumer EIP pattern to let Camel skip already processed files. Will by default use a memory based LRUCache that holds 1000 entries. If noop=true then idempotent will be enabled as well to avoid consuming the same files over and over again.

false

Boolean

idempotentKey (filter)

To use a custom idempotent key. By default the absolute path of the file is used. You can use the File Language, for example to use the file name and file size, you can do: idempotentKey=\${file:name}-\${file:size}

String

idempotentRepository (filter)

A pluggable repository org.apache.camel.spi.IdempotentRepository which by default use MemoryMessageIdRepository if none is specified and idempotent is true.

IdempotentRepository

include (filter)

Is used to include files, if filename matches the regex pattern (matching is case in-sensitive). Notice if you use symbols such as plus sign and others you would need to configure this using the RAW() syntax if configuring this as an endpoint uri. See more details at configuring endpoint uris

String

maxDepth (filter)

The maximum depth to traverse when recursively processing a directory.

2147483647

int

maxMessagesPerPoll (filter)

To define a maximum messages to gather per poll. By default no maximum is set. Can be used to set a limit of e.g. 1000 to avoid when starting up the server that there are thousands of files. Set a value of 0 or negative to disabled it. Notice: If this option is in use then the File and FTP components will limit before any sorting. For example if you have 100000 files and use maxMessagesPerPoll=500, then only the first 500 files will be picked up, and then sorted. You can use the eagerMaxMessagesPerPoll option and set this to false to allow to scan all files first and then sort afterwards.

int

minDepth (filter)

The minimum depth to start processing when recursively processing a directory. Using minDepth=1 means the base directory. Using minDepth=2 means the first sub directory.

int

move (filter)

Expression (such as Simple Language) used to dynamically set the filename when moving it after processing. To move files into a .done subdirectory just enter .done.

String

exclusiveReadLockStrategy (lock)

Pluggable read-lock as a org.apache.camel.component.file.GenericFileExclusiveReadLockStrategy implementation.

GenericFileExclusiveReadLockStrategy

readLock (lock)

Used by consumer, to only poll the files if it has exclusive read-lock on the file (i.e. the file is not in-progress or being written). Camel will wait until the file lock is granted. This option provides the build in strategies: - none - No read lock is in use - markerFile - Camel creates a marker file (fileName.camelLock) and then holds a lock on it. This option is not available for the FTP component - changed - Changed is using file length/modification timestamp to detect whether the file is currently being copied or not. Will at least use 1 sec to determine this, so this option cannot consume files as fast as the others, but can be more reliable as the JDK IO API cannot always determine whether a file is currently being used by another process. The option readLockCheckInterval can be used to set the check frequency. - fileLock - is for using java.nio.channels.FileLock. This option is not avail for Windows OS and the FTP component. This approach should be avoided when accessing a remote file system via a mount/share unless that file system supports distributed file locks. - rename - rename is for using a try to rename the file as a test if we can get exclusive read-lock. - idempotent - (only for file component) idempotent is for using a idempotentRepository as the read-lock. This allows to use read locks that supports clustering if the idempotent repository implementation supports that. - idempotent-changed - (only for file component) idempotent-changed is for using a idempotentRepository and changed as the combined read-lock. This allows to use read locks that supports clustering if the idempotent repository implementation supports that. - idempotent-rename - (only for file component) idempotent-rename is for using a idempotentRepository and rename as the combined read-lock. This allows to use read locks that supports clustering if the idempotent repository implementation supports that.Notice: The various read locks is not all suited to work in clustered mode, where concurrent consumers on different nodes is competing for the same files on a shared file system. The markerFile using a close to atomic operation to create the empty marker file, but its not guaranteed to work in a cluster. The fileLock may work better but then the file system need to support distributed file locks, and so on. Using the idempotent read lock can support clustering if the idempotent repository supports clustering, such as Hazelcast Component or Infinispan. The value can be one of: none, markerFile, fileLock, rename, changed, idempotent, idempotent-changed, idempotent-rename

none

String

readLockCheckInterval (lock)

Interval in millis for the read-lock, if supported by the read lock. This interval is used for sleeping between attempts to acquire the read lock. For example when using the changed read lock, you can set a higher interval period to cater for slow writes. The default of 1 sec. may be too fast if the producer is very slow writing the file. Notice: For FTP the default readLockCheckInterval is 5000. The readLockTimeout value must be higher than readLockCheckInterval, but a rule of thumb is to have a timeout that is at least 2 or more times higher than the readLockCheckInterval. This is needed to ensure that amble time is allowed for the read lock process to try to grab the lock before the timeout was hit.

1000

long

readLockDeleteOrphanLockFiles (lock)

Whether or not read lock with marker files should upon startup delete any orphan read lock files, which may have been left on the file system, if Camel was not properly shutdown (such as a JVM crash). If turning this option to false then any orphaned lock file will cause Camel to not attempt to pickup that file, this could also be due another node is concurrently reading files from the same shared directory.

true

boolean

readLockLoggingLevel (lock)

Logging level used when a read lock could not be acquired. By default a DEBUG is logged. You can change this level, for example to OFF to not have any logging. This option is only applicable for readLock of types: changed, fileLock, idempotent, idempotent-changed, idempotent-rename, rename. The value can be one of: TRACE, DEBUG, INFO, WARN, ERROR, OFF

DEBUG

LoggingLevel

readLockMarkerFile (lock)

Whether to use marker file with the changed, rename, or exclusive read lock types. By default a marker file is used as well to guard against other processes picking up the same files. This behavior can be turned off by setting this option to false. For example if you do not want to write marker files to the file systems by the Camel application.

true

boolean

readLockMinAge (lock)

This option is applied only for readLock=changed. It allows to specify a minimum age the file must be before attempting to acquire the read lock. For example use readLockMinAge=300s to require the file is at last 5 minutes old. This can speedup the changed read lock as it will only attempt to acquire files which are at least that given age.

long

readLockMinLength (lock)

This option is applied only for readLock=changed. It allows you to configure a minimum file length. By default Camel expects the file to contain data, and thus the default value is 1. You can set this option to zero, to allow consuming zero-length files.

long

readLockRemoveOnCommit (lock)

This option is applied only for readLock=idempotent. It allows to specify whether to remove the file name entry from the idempotent repository when processing the file is succeeded and a commit happens. By default the file is not removed which ensures that any race-condition do not occur so another active node may attempt to grab the file. Instead the idempotent repository may support eviction strategies that you can configure to evict the file name entry after X minutes - this ensures no problems with race conditions. See more details at the readLockIdempotentReleaseDelay option.

false

boolean

readLockRemoveOnRollback (lock)

This option is applied only for readLock=idempotent. It allows to specify whether to remove the file name entry from the idempotent repository when processing the file failed and a rollback happens. If this option is false, then the file name entry is confirmed (as if the file did a commit).

true

boolean

readLockTimeout (lock)

Optional timeout in millis for the read-lock, if supported by the read-lock. If the read-lock could not be granted and the timeout triggered, then Camel will skip the file. At next poll Camel, will try the file again, and this time maybe the read-lock could be granted. Use a value of 0 or lower to indicate forever. Currently fileLock, changed and rename support the timeout. Notice: For FTP the default readLockTimeout value is 20000 instead of 10000. The readLockTimeout value must be higher than readLockCheckInterval, but a rule of thumb is to have a timeout that is at least 2 or more times higher than the readLockCheckInterval. This is needed to ensure that amble time is allowed for the read lock process to try to grab the lock before the timeout was hit.

10000

long

backoffErrorThreshold (scheduler)

The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.

int

backoffIdleThreshold (scheduler)

The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.

int

backoffMultiplier (scheduler)

To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.

int

delay (scheduler)

Milliseconds before the next poll.

500

FTPS component default trust store

When using the ftpClient. properties related to SSL with the FTPS component, the trust store accept all certificates. If you only want trust selective certificates, you have to configure the trust store with the ftpClient.trustStore.xxx options or by configuring a custom ftpClient.

When using sslContextParameters, the trust store is managed by the configuration of the provided SSLContextParameters instance.

You can configure additional options on the ftpClient and ftpClientConfig from the URI directly by using the ftpClient. or ftpClientConfig. prefix.

For example to set the setDataTimeout on the FTPClient to 30 seconds you can do:

from("ftp://foo@myserver?password=secret&ftpClient.dataTimeout=30000").to("bean:foo");

You can mix and match and have use both prefixes, for example to configure date format or timezones.

from("ftp://foo@myserver?password=secret&ftpClient.dataTimeout=30000&ftpClientConfig.serverLanguageCode=fr").to("bean:foo");

You can have as many of these options as you like.

See the documentation of the Apache Commons FTP FTPClientConfig for possible options and more details. And as well for Apache Commons FTP FTPClient.

If you do not like having many and long configuration in the url you can refer to the ftpClient or ftpClientConfig to use by letting Camel lookup in the Registry for it.

For example:

   <bean id="myConfig" class="org.apache.commons.net.ftp.FTPClientConfig">
       <property name="lenientFutureDates" value="true"/>
       <property name="serverLanguageCode" value="fr"/>
   </bean>

And then let Camel lookup this bean when you use the # notation in the url.

from("ftp://foo@myserver?password=secret&ftpClientConfig=#myConfig").to("bean:foo");

Examples

ftp://someone@someftpserver.com/public/upload/images/holiday2008?password=secret&binary=true

ftp://someoneelse@someotherftpserver.co.uk:12049/reports/2008/password=secret&binary=false

ftp://publicftpserver.com/download

Concurrency

FTP Consumer does not support concurrency

The FTP consumer (with the same endpoint) does not support concurrency (the backing FTP client is not thread safe).
You can use multiple FTP consumers to poll from different endpoints. It is only a single endpoint that does not support concurrent consumers.

The FTP producer does not have this issue, it supports concurrency.

More information

This component is an extension of the File component. So there are more samples and details on the File component page.

Default when consuming files

The FTP consumer will by default leave the consumed files untouched on the remote FTP server. You have to configure it explicitly if you want it to delete the files or move them to another location. For example you can use delete=true to delete the files, or use move=.done to move the files into a hidden done sub directory.

The regular File consumer is different as it will by default move files to a .camel sub directory. The reason Camel does not do this by default for the FTP consumer is that it may lack permissions by default to be able to move or delete files.

limitations

The option readLock can be used to force Camel not to consume files that is currently in the progress of being written. However, this option is turned off by default, as it requires that the user has write access. See the options table at File2 for more details about read locks.
There are other solutions to avoid consuming files that are currently being written over FTP; for instance, you can write to a temporary destination and move the file after it has been written.

When moving files using move or preMove option the files are restricted to the FTP_ROOT folder. That prevents you from moving files outside the FTP area. If you want to move files to another area you can use soft links and move files into a soft linked folder.

Message Headers

The following message headers can be used to affect the behavior of the component

Header Description

Header	Description
`CamelFileName`	Specifies the output file name (relative to the endpoint directory) to be used for the output message when sending to the endpoint. If this is not present and no expression either, then a generated message ID is used as the filename instead.
`CamelFileNameProduced`	The actual filepath (path + name) for the output file that was written. This header is set by Camel and its purpose is providing end-users the name of the file that was written.
`CamelFileIndex`	Current index out of total number of files being consumed in this batch.
`CamelFileSize`	Total number of files being consumed in this batch.
`CamelFileHost`	The remote hostname.
`CamelFileLocalWorkPath`	Path to the local work file, if local work directory is used.

CamelFileName

Specifies the output file name (relative to the endpoint directory) to be used for the output message when sending to the endpoint. If this is not present and no expression either, then a generated message ID is used as the filename instead.

CamelFileNameProduced

The actual filepath (path + name) for the output file that was written. This header is set by Camel and its purpose is providing end-users the name of the file that was written.

CamelFileIndex

Current index out of total number of files being consumed in this batch.

CamelFileSize

Total number of files being consumed in this batch.

CamelFileHost

The remote hostname.

CamelFileLocalWorkPath

Path to the local work file, if local work directory is used.

In addition the FTP/FTPS consumer and producer will enrich the Camel Message with the following headers

Header Description

Header	Description
`CamelFtpReplyCode`	The FTP client reply code (the type is a integer)
`CamelFtpReplyString`	The FTP client reply string

CamelFtpReplyCode

The FTP client reply code (the type is a integer)

CamelFtpReplyString

The FTP client reply string

About timeouts

The two set of libraries (see top) has different API for setting timeout. You can use the connectTimeout option for both of them to set a timeout in millis to establish a network connection. An individual soTimeout can also be set on the FTP/FTPS, which corresponds to using ftpClient.soTimeout. Notice SFTP will automatically use connectTimeout as its soTimeout. The timeout option only applies for FTP/FTPS as the data timeout, which corresponds to the ftpClient.dataTimeout value. All timeout values are in millis.

Using Local Work Directory

Camel supports consuming from remote FTP servers and downloading the files directly into a local work directory. This avoids reading the entire remote file content into memory as it is streamed directly into the local file using FileOutputStream.

Camel will store to a local file with the same name as the remote file, though with .inprogress as extension while the file is being downloaded. Afterwards, the file is renamed to remove the .inprogress suffix. And finally, when the Exchange is complete the local file is deleted.

So if you want to download files from a remote FTP server and store it as files then you need to route to a file endpoint such as:

from("ftp://someone@someserver.com?password=secret&localWorkDirectory=/tmp").to("file://inbox");

The route above is ultra efficient as it avoids reading the entire file content into memory. It will download the remote file directly to a local file stream. The java.io.File handle is then used as the Exchange body. The file producer leverages this fact and can work directly on the work file java.io.File handle and perform a java.io.File.rename to the target filename. As Camel knows it’s a local work file, it can optimize and use a rename instead of a file copy, as the work file is meant to be deleted anyway.

Stepwise changing directories

Camel FTP can operate in two modes in terms of traversing directories when consuming files (eg downloading) or producing files (eg uploading)

stepwise
not stepwise

You may want to pick either one depending on your situation and security issues. Some Camel end users can only download files if they use stepwise, while others can only download if they do not.

You can use the stepwise option to control the behavior.

Note that stepwise changing of directory will in most cases only work when the user is confined to it’s home directory and when the home directory is reported as "/".

The difference between the two of them is best illustrated with an example. Suppose we have the following directory structure on the remote FTP server we need to traverse and download files:

/
/one
/one/two
/one/two/sub-a
/one/two/sub-b

And that we have a file in each of sub-a (a.txt) and sub-b (b.txt) folder.

Using stepwise=true (default mode)

As you can see when not using stepwise, there are no CD operation invoked at all.

Samples

In the sample below we set up Camel to download all the reports from the FTP server once every hour (60 min) as BINARY content and store it as files on the local file system.

And the route using Spring DSL:

  <route>
     <from uri="ftp://scott@localhost/public/reports?password=tiger&amp;binary=true&amp;delay=60000"/>
     <to uri="file://target/test-reports"/>
  </route>

Consuming a remote FTPS server (implicit SSL) and client authentication

from("ftps://admin@localhost:2222/public/camel?password=admin&securityProtocol=SSL&implicit=true
      &ftpClient.keyStore.file=./src/test/resources/server.jks
      &ftpClient.keyStore.password=password&ftpClient.keyStore.keyPassword=password")
  .to("bean:foo");

Consuming a remote FTPS server (explicit TLS) and a custom trust store configuration

from("ftps://admin@localhost:2222/public/camel?password=admin&ftpClient.trustStore.file=./src/test/resources/server.jks&ftpClient.trustStore.password=password")
  .to("bean:foo");

Custom filtering

Camel supports pluggable filtering strategies. This strategy it to use the build in org.apache.camel.component.file.GenericFileFilter in Java. You can then configure the endpoint with such a filter to skip certain filters before being processed.

In the sample we have built our own filter that only accepts files starting with report in the filename.

And then we can configure our route using the filter attribute to reference our filter (using # notation) that we have defined in the spring XML file:

   <!-- define our sorter as a plain spring bean -->
   <bean id="myFilter" class="com.mycompany.MyFileFilter"/>

  <route>
    <from uri="ftp://someuser@someftpserver.com?password=secret&amp;filter=#myFilter"/>
    <to uri="bean:processInbox"/>
  </route>

Filtering using ANT path matcher

The ANT path matcher is a filter that is shipped out-of-the-box in the camel-spring jar. So you need to depend on camel-spring if you are using Maven.
The reason is that we leverage Spring’s AntPathMatcher to do the actual matching.

The file paths are matched with the following rules:

? matches one character
* matches zero or more characters
** matches zero or more directories in a path

The sample below demonstrates how to use it:

Using a proxy with SFTP

To use an HTTP proxy to connect to your remote host, you can configure your route in the following way:

<!-- define our sorter as a plain spring bean -->
<bean id="proxy" class="com.jcraft.jsch.ProxyHTTP">
  <constructor-arg value="localhost"/>
  <constructor-arg value="7777"/>
</bean>

<route>
  <from uri="sftp://localhost:9999/root?username=admin&password=admin&proxy=#proxy"/>
  <to uri="bean:processFile"/>
</route>

You can also assign a user name and password to the proxy, if necessary. Please consult the documentation for com.jcraft.jsch.Proxy to discover all options.

Setting preferred SFTP authentication method

If you want to explicitly specify the list of authentication methods that should be used by sftp component, use preferredAuthentications option. If for example you would like Camel to attempt to authenticate with private/public SSH key and fallback to user/password authentication in the case when no public key is available, use the following route configuration:

from("sftp://localhost:9999/root?username=admin&password=admin&preferredAuthentications=publickey,password").
  to("bean:processFile");

Consuming a single file using a fixed name

When you want to download a single file and knows the file name, you can use fileName=myFileName.txt to tell Camel the name of the file to download. By default the consumer will still do a FTP LIST command to do a directory listing and then filter these files based on the fileName option. Though in this use-case it may be desirable to turn off the directory listing by setting useList=false. For example the user account used to login to the FTP server may not have permission to do a FTP LIST command. So you can turn off this with useList=false, and then provide the fixed name of the file to download with fileName=myFileName.txt, then the FTP consumer can still download the file. If the file for some reason does not exist, then Camel will by default throw an exception, you can turn this off and ignore this by setting ignoreFileNotFoundOrPermissionError=true.

For example to have a Camel route that pickup a single file, and delete it after use you can do

from("ftp://admin@localhost:21/nolist/?password=admin&stepwise=false&useList=false&ignoreFileNotFoundOrPermissionError=true&fileName=report.txt&delete=true")
  .to("activemq:queue:report");

Notice that we have used all the options we talked above.

You can also use this with ConsumerTemplate. For example to download a single file (if it exists) and grab the file content as a String type:

String data = template.retrieveBodyNoWait("ftp://admin@localhost:21/nolist/?password=admin&stepwise=false&useList=false&ignoreFileNotFoundOrPermissionError=true&fileName=report.txt&delete=true", String.class);

Debug logging

This component has log level TRACE that can be helpful if you have problems.

Spring Boot Auto-Configuration

When using ftp with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-ftp-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 13 options, which are listed below.

Name	Description	Default	Type
camel.component.ftp.basic-property-binding	Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities	false	Boolean
camel.component.ftp.bridge-error-handler	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	Boolean
camel.component.ftp.enabled	Whether to enable auto configuration of the \ftp component. This is enabled by default.		Boolean
camel.component.ftp.lazy-start-producer	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	Boolean
