Languages

To support flexible and powerful Enterprise Integration Patterns, Camel supports various Languages to create an Expression or Predicate within either the Routing Domain Specific Language or the XML Configuration.

Note

Combining Predicates*

When creating predicates (expressions that evaluate to true or false), you can combine several predicates — regardless of the language they are built with — by using the PredicateBuilder class. For more information, see Compound Predicates.

The following is the list of currently supported languages:

Bean Language for using Java for expressions
Constant
Header
JSonPath
Mvel
OGNL
Ref Language
ExchangeProperty
- Groovy
Simple
- File Language
Spring Expression Language
Tokenizer
XPath
XQuery

Most of these languages are also supported used as Annotation Based Expression Language.
