OGNL

Camel allows OGNL to be used as an Expression or Predicate the DSL or Xml Configuration.

For example you could use OGNL inside a Message Filter in XML

<route>
  <from uri="seda:foo"/>
  <filter>
    <ognl>request.headers.foo = 'bar'</ognl>
    <to uri="seda:bar"/>
  </filter>
</route>

You could use OGNL to create an Predicate in a Message Filter or as an Expression for a Recipient List

Syntax

Expression	Type	Description
exchange	Exchange	the Exchange object
exception	Thorwable	the Exchange exception (if any)
exchangeId	String	the exchange Id
fault	Message	the Fault message (if any)
request	Message	the exchange.in message
response	Message	the exchange.out message (if any)
properties	Map	the exchange properties
property(name)	Object	the property by the given name
property(name, type)	Type	the property by the given name as the given type

You can use OGNL dot notation to invoke operations. If you for instance have a body that contains a POJO that has a getFamiliyName method then you can construct the syntax as follows:

"request.body.familyName"
   // or 
"getRequest().getBody().getFamilyName()"
