Property Expression Language
The Property Expression Language allows you to extract values of named exchange properties.
Note |
---|
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:
Wiki Markup |
---|
{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:
Wiki Markup |
---|
{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)

from("direct:a").recipientList().property("myProperty"); |
Dependencies
The Property language is part of camel-core.
