Header Expression Language

The Header Expression Language allows you to extract values of named headers.

Available as of Camel 1.5

Example usage

The recipientList element of the Spring DSL can utilize a header expression like:

  <from uri="direct:a"/>

In this case, the list of recipients are contained in the header 'recipientListHeader'.

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 header is not a parameter but a stacked method call)



The Header language is part of camel-core.
