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 an exchangeProperty expression. In this example, 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 e.g., 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.
