Apache CXF REST Services w/ Spring AOP

Question

I'm trying to get Apache CXF JAX-RS services working with Spring AOP. I've created a simple logging class:

    public class AOPLogger{

      public void logBefore(){
        System.out.println("Logging Before!");
      }

}

My Spring configuration (beans.xml):

  <aop:config>
    <aop:aspect id="aopLogger" ref="test.aop.AOPLogger">
      <aop:before method="logBefore" pointcut="execution(* test.rest.RestService.*(..))"/>
    </aop:aspect>
   </aop:config>
   <bean id="aopLogger" class="test.aop.AOPLogger"/>

I always get an NPE in RestService when a call is made to a Method getServletRequest(), which has:

return messageContext.getHttpServletRequest();

If I remove the aop configuration or comment it out from my beans.xml, everything works fine.

All of my actual Rest services extend test.rest.RestService (which is a class) and call getServletRequest(). I'm just trying to just get AOP up and running based off of the example in the CXF JAX-RS documentation. Does anyone have any idea what I'm doing wrong? Thanks!

You just need to have your resource class implementing some simple interface with a method

@Context void setMessageContext(MessageContext mc) {}

this will enable the CXF SpringAOPHelper to discover the method
