[jboss-user] [JBoss AOP] - Maybe I just don't get it
I have a service that I want to instrument to do some diagnostics. I thought that this
presented a good opportunity to come up to speed on AOP.
1. I created an interceptor class .
@InterceptorDef
| @Bind (pointcut = "execution(public Boolean
com.eLynx.Service.PackageProcessing.PackageProcessingMessageHandler->processMessage(..))")
| public class ProcessMessageInterceptor implements Interceptor
| {
|
| /**
| * Method: getName
| *
| *
| * @return
| */
|
| public String getName ()
| {
| return "ProcessMessageInterceptor";
| }
|
| public Object invoke (Invocation invocation) throws Throwable
| {
| try
| {
| System.out.println ("<<< Entering
ProcessMessageInterceptor");
| return invocation.invokeNext ();
| }
| finally
| {
| System.out.println (">>> Leaving
ProcessMessageInterceptor");
| }
| }
| }
2. I enabled loadTime weaving and added the pluggable-instrumentor.jar
3. I scoped my interceptor deployment to the same as the service with the method I want
to intercept.
| <?xml version="1.0" encoding="UTF-8"
standalone="yes"?>
| <aop>
|
<loader-repository>com.eLynx:loader=PackageProcessingService</loader-repository>
| </aop>
|
4. I packaged up my interceptor class and -aop.xml file in a jar with .aop extension.
The xml file is in a META-INF directory.
5. I deploy the .aop file and the deployer picks it up. It logs that it is using the
class loader I expect.
6. I invoke the method I want intercepted and noting happens.
The method I want intercepted is:
| @Override public boolean processMessage (Message aMessage,
| MessageReceiver aMessageReceiver)
| {
| ...
| }
I don't really now what to do now. Any ideas?
