Chapter 26. Exchange Property

Overview

The exchange property language provides a convenient way of accessing exchange properties. When you supply a key that matches one of the exchange property names, the exchange property language returns the corresponding value.

The exchange property language is part of camel-core.

XML example

For example, to implement the recipient list pattern when the listOfEndpoints exchange property contains the recipient list, you could define a route as follows:

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

Java example

The same recipient list example can be implemented in Java as follows:

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