Hi Sasha,
You can access all annotations on the method and/or the defining class
using the MethodInvocation parameter of MethodInterceptor.invoke().
Something like this:
public class MyInterceptor implements MethodInterceptor {
public Object invoke(MethodInvocation methodInvocation) throws
Throwable {
Method method = methodInvocation.getMethod();
MyAnnotation annotation = method.getAnnotation(Transactional.class);
....
}
}
For a full example check out guice-persist's transactional interceptor:
https://code.google.com/p/google-guice/source/browse/extensions/persist/src/com/google/inject/persist/jpa/JpaLocalTxnInterceptor.java
Line 56 is where the annotation is extracted.
