我想捕获实现Processor接口的类抛出的异常.在方面我需要访问处理器,它会抛出异常.我定义了以下切入点:

@Pointcut("target(some.package.Processor) && args(message)")
  public void processor(Message message) {
}

方面:

@AfterThrowing(pointcut="processor(message)", throwing="ex")
public void onExceptionInProcessor(Processor target, Exception ex, Message message) {
  // code skipped
}

但是,我得到以下异常:
