1.bean的生命周期第一步回去解析所有的advisor

 2.第四个是我们之前开启的注解@EnableAspectJAutoProxy

 3.org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator#postProcessBeforeInstantiation

 4.org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator#isInfrastructureClass

 false

5.

6.

7. org.springframework.aop.aspectj.annotation.BeanFactoryAspectJAdvisorsBuilder#buildAspectJAdvisors

判断当前bean上是否有@Aspect 

8.org.springframework.aop.aspectj.annotation.ReflectiveAspectJAdvisorFactory#getAdvisors

===================下面开始解析after===============

org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator#postProcessAfterInitialization

 

 

 

 org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator#findCandidateAdvisors

 总结：首先执行bean的生命周期第一步，会去寻找所有的@Aspect的bean,然后遍历里面的所有方法，判断是否有5个advice,如果有的话把其加入到advisors中，最后的到的产物：
