Spring AOP advice is called twice

Question

I have the following Spring AOP advice and I can\'t find out why it is called twice:

@Component
@Aspect
public class LoggingAspects {

    Logger logger = Lo         


        

Answer 1

1. hint

Do you use JavaConfig or xml? If you're using both, it could be that the Aspect is being processed two times by the Spring IoC container.

2. hint

I don't annotate aspects with @Component annoation, try to remove it, maybe because of that is being processed twice by Spring.

Answer 2

I found that the advice can be called twice if the aspect is declared as request-scoped. In this case the same bean is registered twice as an interceptor with different names: someAspect and scopedTarget.someAspect. I solved this issue by making the Aspect a singleton.
