Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the early version of the new website
https://camel.apache.org/staging/
We would very much like to receive any feedback on the new site, please join the discussion on the Camel user mailing list.

Property Expression Language

The Property Expression Language allows you to extract values of named exchange properties.

From Camel 2.15 onwards the property language has been renamed to exchangeProperty to avoid ambiguity, confusion and clash with properties as a general term. So use exchangeProperty instead of property when using Camel 2.15 onwards.

 

Example usage

The recipientList element of the Spring DSL can utilize a property expression like:

{snippet:id=e1|lang=xml|url=camel/trunk/components/camel-spring/src/test/resources/org/apache/camel/spring/processor/recipientListWithStringDelimitedProperty.xml}

In this case, the list of recipients are contained in the property 'myProperty'.

And the same example in Java DSL:

{snippet:id=example|lang=java|url=camel/trunk/camel-core/src/test/java/org/apache/camel/processor/RecipientListWithStringDelimitedPropertyTest.java}

And with a slightly different syntax where you use the builder to the fullest (i.e. avoid using parameters but using stacked operations, notice that property is not a parameter but a stacked method call)

java from("direct:a").recipientList().property("myProperty");

Dependencies

The Property language is part of camel-core.
