增强通知

1. Around

2. Befroe

3. After

4. AfterReturning

5. AfterThrowing

工具类

BeanFactoryAspectJAdvisorsBuilder

ReflectiveAspectJAdvisorFactory

增强通知类

• AsepctJAroundAdvice

• AsepctJMethodBeforeAdvice

• AsepctJAfterAdvice

• AsepctJAfterReturningAdvice

• AsepctJAfterThrowingAdvice

AdviceAdpater

适配转化成MethodInterceptor

由于AsepctJAroundAdvice和AsepctJAfterAdvice已经实现了MethodInterceptor接口不需要再做适配

• MethodBeforeAdviceAdapter

• AfterReturningAdeviceAdapter

• ThrowingAdapter

AdvisorAdapterRegistry

DefaultAdvisorAdapterRegistry

GlobalAdvisorAdpatorRegistry

MethodMatcher

MethodInterceptor

AsepctJAroundAdvice和AsepctJAfterAdvice已经实现了MethodInterceptor接口

• MethodBeforeAdviceInterceptor

• AfterReturningAdviceInterceptor

• ThrowsAdviceInterceptor

• ReflectiveMethodInvocation

AopProxy

• CglibAopProxy

• JdkDynamicAopProxy

AnnotationAwareAspectJAutoProxyCreator

重点方法

buildAspectJAdvisors 查询切面配置类和收集切面信息。

findCandidateAdvisors 查找可用的切面

流程图

缓存切面配置信息

实例前处理器-AbstractAutoProxyCreator#postProcessBeforeInstantiation

AnnotationAwareApsectJAutoProxyCreator#findCandidateAdvisors

--> BeanFactoryAspectJAdvisorsBuilder.buildAspectJAdvsiors 查询切面配置类缓存到内部advisorsCache

----> ReflectiveAspectJAdvisorsFactory.getAdvice 将注解转化成增强通知类Advice
