Question

The question is short and simple: Is there a way to get the Method object from an apsectj ProceedingJoinPoint?

Currently I am doing

Class[] parameterTypes = new Class[joinPoint.getArgs().length];
Object[] args = joinPoint.getArgs();
for(int i=0; i<args.length; i++) {
    if(args[i] != null) {
        parameterTypes[i] = args[i].getClass();
    }
    else {
        parameterTypes[i] = null;
    }
}

String methodName = joinPoint.getSignature().getName();
Method method = joinPoint.getSignature()
    .getDeclaringType().getMethod(methodName, parameterTypes);

but I don’t think this is the way to go …

Answer 1

Your method is not wrong, but there’s a better one. You have to cast to MethodSignature

MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
