Call different proxyied method from Spring Aspect

I have two different aspects. How do I ensure that when calling method from one aspect, it will still go through proxy chain?

Here is relevant code:

Inner aspect: 

@Around("withinReplicatedRepository() && entityMethod() && insertMethod()")
public Object trackInsert(ProceedingJoinPoint jp) throws Throwable {
    return trackChange(jp, ChangeType.INSERT, jp.getArgs()[0]);
}

Outer aspect: 

@Around("withinReplicatedRepository() && entityMethod() && autoSaveRepository() && saveMethod()")
public Object saveEntity(ProceedingJoinPoint jp) throws Throwable {
    TransactionUtil.ensureTransactional();

    Object entity = jp.getArgs()[0];
    AutoSaveRepository repository = (AutoSaveRepository)jp.getTarget();
    if (repository.exists(entity)) {
        repository.update(entity);
    } else {
        repository.insert(entity);
    }
    return null;
}

Usage: 

AutoSaveRepository<MyEntity> repo = ...;
repo.save(entity);

My problem is that jp.getTarget() will return original class, thus repository.insert() will not be captured by trackInsert.

You can try

AopContext.currentProxy()

See Javadoc.

The prerequisite is that you activate proxy exposure, though:

  • In XML you can do this since Spring 3.0.3 via
    <aop:aspectj-autoproxy expose-proxy="true"/>.
  • In annotation-style config your can do it since 4.3.1 via
    @EnableAspectJAutoProxy(proxyTargetClass = true, exposeProxy = true),
    see Javadoc
