ExchangeProperty Expression Language

The Property ExchangeProperty 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 exchangeProperty 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'.

Code Block
<route>
  <from uri="direct:a" />
  <recipientList>
    <exchangeProperty>myProperty</exchangeProperty>
  </recipientList>
</route>

 

And the same example in Java DSL:

...

Code Block
from("direct:a").recipientList(exchangeProperty("myProperty"));

 

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 exchangeProperty is not a parameter but a stacked method call)

Code Block
java
java
  from("direct:a").recipientList().propertyexchangeProperty("myProperty");

Dependencies

The Property ExchangeProperty language is part of camel-core.
