boolean

camel.main.autoConfiguration Enabled

Whether auto configuration of components, dataformats, languages is enabled or not. When enabled the configuration parameters are loaded from the properties component and optionally from the classpath file META-INF/services/org/apache/camel/autowire.properties. You can prefix the parameters in the properties file with: - camel.component.name.option1=value1 - camel.component.name.option2=value2 - camel.dataformat.name.option1=value1 - camel.dataformat.name.option2=value2 - camel.language.name.option1=value1 - camel.language.name.option2=value2 Where name is the name of the component, dataformat or language such as seda,direct,jaxb.

boolean

camel.main.autoStartup

Sets whether the object should automatically start when Camel starts. Important: Currently only routes can be disabled, as CamelContext’s are always started. Note: When setting auto startup false on CamelContext then that takes precedence and no routes is started. You would need to start CamelContext explicit using the org.apache.camel.CamelContext.start() method, to start the context, and then you would need to start the routes manually using CamelContext.getRouteController().startRoute(String). Default is true to always start up.

boolean

camel.main.autowireComponent Properties

Whether autowiring components with properties that are of same type, which has been added to the Camel registry, as a singleton instance. This is used for convention over configuration to inject DataSource, AmazonLogin instances to the components. This option is default enabled.

By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN/ERROR level and ignored. The default value is false.

boolean

camel.main.endpointLazyStart 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. The default value is false.

Configures the number of permitted calls when the CircuitBreaker is half open. The size must be greater than 0. Default size is 10.

Integer

camel.resilience4j.sliding WindowSize

Configures the size of the sliding window which is used to record the outcome of calls when the CircuitBreaker is closed. slidingWindowSize configures the size of the sliding window. Sliding window can either be count-based or time-based. If slidingWindowType is COUNT_BASED, the last slidingWindowSize calls are recorded and aggregated. If slidingWindowType is TIME_BASED, the calls of the last slidingWindowSize seconds are recorded and aggregated. The slidingWindowSize must be greater than 0. The minimumNumberOfCalls must be greater than 0. If the slidingWindowType is COUNT_BASED, the minimumNumberOfCalls cannot be greater than slidingWindowSize . If the slidingWindowType is TIME_BASED, you can pick whatever you want. Default slidingWindowSize is 100.

Integer

camel.resilience4j.sliding WindowType

Configures the type of the sliding window which is used to record the outcome of calls when the CircuitBreaker is closed. Sliding window can either be count-based or time-based. If slidingWindowType is COUNT_BASED, the last slidingWindowSize calls are recorded and aggregated. If slidingWindowType is TIME_BASED, the calls of the last slidingWindowSize seconds are recorded and aggregated. Default slidingWindowType is COUNT_BASED.

String

camel.resilience4j.slowCall DurationThreshold

Configures the duration threshold (seconds) above which calls are considered as slow and increase the slow calls percentage. Default value is 60 seconds.

Integer

camel.resilience4j.slowCall RateThreshold

Configures a threshold in percentage. The CircuitBreaker considers a call as slow when the call duration is greater than slowCallDurationThreshold(Duration. When the percentage of slow calls is equal or greater the threshold, the CircuitBreaker transitions to open and starts short-circuiting calls. The threshold must be greater than 0 and not greater than 100. Default value is 100 percentage which means that all recorded calls must be slower than slowCallDurationThreshold.

Float

camel.resilience4j.timeout CancelRunningFuture

String

camel.resilience4j.wait DurationInOpenState

Configures the wait duration (in seconds) which specifies how long the CircuitBreaker should stay open, before it switches to half open. Default value is 60 seconds.

Integer

camel.resilience4j.writable StackTraceEnabled

Enables writable stack traces. When set to false, Exception.getStackTrace returns a zero length array. This may be used to reduce log spam when the circuit breaker is open as the cause of the exceptions is already known (the circuit breaker is short-circuiting calls).

Boolean

camel.rest.apiComponent

Sets the name of the Camel component to use as the REST API (such as swagger)

String

camel.rest.apiContextIdPattern

Optional CamelContext id pattern to only allow Rest APIs from rest services within CamelContext’s which name matches the pattern. The pattern name refers to the CamelContext name, to match on the current CamelContext only. For any other value, the pattern uses the rules from org.apache.camel.support.EndpointHelper#matchPattern(String,String)

String

camel.rest.apiContextListing

Sets whether listing of all available CamelContext’s with REST services in the JVM is enabled. If enabled it allows to discover these contexts, if false then only the current CamelContext is in use.

boolean

camel.rest.apiContextPath

Sets a leading API context-path the REST API services will be using. This can be used when using components such as camel-servlet where the deployed web application is deployed using a context-path.

String

camel.rest.apiContextRouteId

Sets the route id to use for the route that services the REST API. The route will by default use an auto assigned route id.

String

camel.rest.apiHost

To use an specific hostname for the API documentation (eg swagger) This can be used to override the generated host with this configured hostname

String

camel.rest.apiProperties

Sets additional options on api level

Map

camel.rest.apiVendorExtension

Whether vendor extension is enabled in the Rest APIs. If enabled then Camel will include additional information as vendor extension (eg keys starting with x-) such as route ids, class names etc. Not all 3rd party API gateways and tools supports vendor-extensions when importing your API docs.

boolean

camel.rest.bindingMode

Sets the binding mode to be used by the REST consumer

RestBindingMode

camel.rest.clientRequest Validation

Whether to enable validation of the client request to check whether the Content-Type and Accept headers from the client is supported by the Rest-DSL configuration of its consumes/produces settings. This can be turned on, to enable this check. In case of validation error, then HTTP Status codes 415 or 406 is returned. The default value is false.

boolean

camel.rest.component

Sets the name of the Camel component to use as the REST consumer

String

camel.rest.componentProperties

Sets additional options on component level

Map

camel.rest.consumerProperties

Sets additional options on consumer level

Map

camel.rest.contextPath

Sets a leading context-path the REST services will be using. This can be used when using components such as camel-servlet where the deployed web application is deployed using a context-path. Or for components such as camel-jetty or camel-netty-http that includes a HTTP server.

String

camel.rest.corsHeaders

Sets the CORS headers to use if CORS has been enabled.

Map

camel.rest.dataFormat Properties

Sets additional options on data format level

Map

camel.rest.enableCORS

To specify whether to enable CORS which means Camel will automatic include CORS in the HTTP headers in the response. This option is default false

boolean

camel.rest.endpointProperties

Sets additional options on endpoint level

Sets the hostname to use by the REST consumer

String

camel.rest.hostNameResolver

Sets the resolver to use for resolving hostname

RestHostNameResolver

camel.rest.jsonDataFormat

Sets a custom json data format to be used Important: This option is only for setting a custom name of the data format, not to refer to an existing data format instance.

String

camel.rest.port

Sets the port to use by the REST consumer

int

camel.rest.producerApiDoc

Sets the location of the api document (swagger api) the REST producer will use to validate the REST uri and query parameters are valid accordingly to the api document. This requires adding camel-swagger-java to the classpath, and any miss configuration will let Camel fail on startup and report the error(s). The location of the api document is loaded from classpath by default, but you can use file: or http: to refer to resources to load from file or http url.

String

camel.rest.producerComponent

Sets the name of the Camel component to use as the REST producer

String

camel.rest.scheme

Sets the scheme to use by the REST consumer

String

camel.rest.skipBindingOnError Code

Whether to skip binding output if there is a custom HTTP error code, and instead use the response body as-is. This option is default true.

boolean

camel.rest.useXForwardHeaders

WWhether to use X-Forward headers to set host etc. for Swagger. This option is default true.

boolean
