ExchangeProperty Expression Language

The ExchangeProperty Expression Language allows you to extract values of named exchange properties.

Example usage

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

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

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

And the same example in Java DSL:

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 exchangeProperty is not a parameter but a stacked method call)

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

Dependencies

The ExchangeProperty language is part of camel-core.
