java - Jersey and AOP without Spring -

i using grizzly jersey 2.1. add aspect logging purpose (before , after each method execution). possibile without using spring or google-guice?

thanks

you can achieve similar using monitoring features offered jersey (particularly via event listeners). need create , register instance of applicationeventlistener , requesteventlistener listening resource_method_start , resource_method_finished events.

@provider public class myapplicationeventlistener implements applicationeventlistener {      @override     public void onevent(applicationevent event) {         // noop.     }      @override     public requesteventlistener onrequest(requestevent requestevent) {         return new requesteventlistener() {              @override             public void onevent(final requestevent event) {                 switch (event.gettype()) {                     case resource_method_start:                         logmethod(event.geturiinfo(), true);                         break;                      case resource_method_finished:                         logmethod(event.geturiinfo(), false);                         break;                 }             }              private void logmethod(final extendeduriinfo uriinfo, final boolean entering) {                 final class<?> resource = uriinfo                         .getmatchedresources().get(0).getclass();                  final method method = uriinfo                         .getmatchedresourcemethod()                         .getinvocable()                         .gethandlingmethod();                  if (entering) {                     logger.entering(resource.tostring(), method.tostring());                 } else {                     logger.exiting(resource.tostring(), method.tostring());                 }             }         };     } } 

register listener application:

public class myapplication extends application {      @override     public set<class<?>> getclasses() {         final hashset<class<?>> classes = new hashset<class<?>>();          // add root resources.         classes.add(helloworldresource.class);          // add applicationeventlistener.         classes.add(myapplicationeventlistener.class);          return classes;     } } 

note: these events fired around resource method "to-be-executed" , not sub-resource locators might executed during resource matching phase.

to log each invoked method (even methods invoked jax-rs resource method) refer aspectj project.
