Class AnnotatedEntryPointResolver

org.mule.impl.model.resolvers.AnnotatedEntryPointResolver

All Implemented Interfaces:

EntryPointResolver

public class AnnotatedEntryPointResolver
extends AbstractEntryPointResolver

A Mule EntryPointResolver implementation that will resolve methods on a service class that have Mule expression annotations such as Payload, InboundHeaders It will transform the received message to match the annotated method arguments. For example - public Object doSomething( @XPath ("/foo/bar") String bar, @Payload Document doc, @InboundHeaders("name") String name) { //do stuff } The component method above will be invoked by running the XPath expression on the payload, adding a second parameter as the payload itself and passing in the header 'name' as the third parameter. There are some rules for how components with annotations will be processed -

• For components with more than one method annotated with Mule expression annotations the method name to call needs to be set on the incoming message or endpoint using the MuleProperties.MULE_METHOD_PROPERTY key.
• If the component has only one method annotated with Mule expression annotations there is no need to set the method name to invoke
• Every parameter on the method needs to be annotated
