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("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 is not a parameter but a stacked method call)
from("direct:a").recipientList().property("myProperty");
Dependencies
The Property language is part of camel-core.
