Property Expression Language
The Property Expression Language allows you to extract values of named exchange properties.
Available as of Camel 2.0
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:
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)
The Property language is part of camel-core.
