Groovy Camel Processors

Fuse ESB 7.0 comes with Camel 2.9 components. Camel has groovy support from 2.89 to create predicates and expressions. There is a GroovyRouteBuilder in 2.9 that lets you build dsl in groovy, albeit with java api. This is especially un-groovy when you have to write a .process.

Until a more fluent groovy route builder comes to Fuse, Here is a helper that can make writing groovy processes.

class GroovyRoutes extends GroovyRouteBuilder {
 
 @Autowired
 AuthRestTemplate restTemplate; 
 
 void configure() {
  setupGroovyMethods();
  
  from("direct:resource").routeId("groovyRouteWithProcessor")
   .process{ e ->
    //access json and other groovy goodness
    def slurper = new JsonSlurper()
    // do groovy magic with them    
   }
   .to("mock:result");
 
  
 }
 
 def setupGroovyMethods(){
   //setup expandos for later ease
  org.apache.camel.model.RouteDefinition.metaClass.process = { clo ->
    delegate.process(new Processor(){
     public void process(Exchange e) throws Exception {
       clo.call(e)
     }
    });
   }
 }
}
