Property _expression_ Language

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

Available as of Camel 2.0

Example usage

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

<route>
  <from uri="direct:a" />
  <recipientList>
    <property>myProperty</property>
  </recipientList>
</route>


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



And the same example in Java DSL:





from("direct:a").recipientList(property(PROPERTY_NAME));





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.
