Groovy

Camel supports Groovy among other Scripting Languages to allow an Expression or Predicate to be used in the DSL or Xml Configuration.

To use a Groovy expression use the following Java code

import static org.apache.camel.builder.script.ScriptBuilder.*;

...

... groovy("someGroovyExpression") ...

For example you could use the groovy function to create an Predicate in a Message Filter or as an Expression for a Recipient List

// lets route if a line item is over $100
from("queue:foo").filter(groovy("request.lineItems.any { i -> i.value > 100 }")).to("queue:bar")
