手动代理ProxyFactoryBean继承关系
# ProxyConfig 基础代理信息管理
# \—-AdvisedSupport 维护Advice和Advisor
# \—-ProxyCreatorSupport 持有AopProxyFactory,能够创建AopProxy对象
# \—-ProxyFactoryBean 实现了FactoryBean,具备生成bean代理的能力
ProxyFactoryBean实现了FactoryBean,调用过程如下
# ProxyFactoryBean.getObject
# \—-ProxyFactoryBean.initializeAdvisorChain 转换interceptorNames为若干PointcutAdvisor,保存到advisorArray,在JdkDynamicAopProxy.invoke中使用
# | \—-BeanFactory.getBean 遍历interceptorNames,获取Advice实例
# | \—-ProxyFactoryBean.addAdvisorOnChainCreation
# | \—-ProxyFactoryBean.namedBeanToAdvisor
# | | \—-DefaultAdvisorAdapterRegistry.wrap 把Advice封装成PointcutAdvisor
# | \—-AdvisedSupport.addAdvisor 加到advisors末尾,更新advisorArray,此处增加的所有声明的Advisor,是否满足拦截条件在调用时检查!!!
# \—-ProxyFactoryBean.getSingletonInstance
# \—-ProxyCreatorSupport.createAopProxy 此处将存储有代理配置信息的this传入,即ProxyFActoryBean对象
# | \—-DefaultAopProxyFactory.createAopProxy 利用工厂生成JdkDynamicAopProxy实例
# \—-ProxyFactoryBean.getProxy
# \—-JdkDynamicAopProxy.getProxy 利用jdk动态代理技术生成代理对象
JdkDynamicAopProxy实现了InvocationHandler,调用过程如下
# JdkDynamicAopProxy.invoke
# \—-AdvisedSupport.getInterceptorsAndDynamicInterceptionAdvice 生成拦截器链
# | \—-DefaultAdvisorChainFactory.getInterceptorsAndDynamicInterceptionAdvice
# | \—-AdvisedSupport.getAdvisors 返回advisorArray
# | \—-DefaultAdvisorAdapterRegistry.getInterceptors 遍历Advisor,提取对应的多个MethodInterceptor
# | | \—-AdvisorAdapter.getInterceptor 适配成MethodInterceptor
# | \—-PointcutAdvisor.getPointcut
# | \—-Pointcut.getMethodMatcher
# | \—-MethodMatchers.matches 如果匹配将提取到的拦截器加入到列表返回
# \—-new ReflectiveMethodInvocation() 生成拦截器及目标方法的调用链,责任链模式
# \—-ReflectiveMethodInvocation.proceed
# \—-MethodInterceptor.invoke 遍历拦截器,如果符合拦截条件调用其invoke方法
# \—-ReflectiveMethodInvocation.invokeJoinpoint
# \—-AopUtils.invokeJoinpointUsingReflection 调用被代理对象的真正目标方法
2.基于注解自动代理AnnotationAwareAspectJAutoProxyCreator继承关系
# ProxyConfig 基础代理信息管理
# \—-ProxyProcessorSupport
# \—-AbstractAutoProxyCreator 用于创建自动代理
# \—-AbstractAdvisorAutoProxyCreator 用于创建自动代理时,查找配置文件中配置的Advisor
# \—-AspectJAwareAdvisorAutoProxyCreator
# \—-AnnotationAwareAspectJAutoProxyCreator 用于AspectJ注解的Advisor提取
AnnotationAwareAspectJAutoProxyCreator实现了BeanPostProcessor,调用过程如下
# AbstractAutoProxyCreator.postProcessAfterInitialization
# \—-AbstractAutoProxyCreator.wrapIfNecessary 检查是否需要返回当前bean的代理
# \—-AbstractAdvisorAutoProxyCreator.getAdvicesAndAdvisorsForBean 模板方法
# | \—-AbstractAdvisorAutoProxyCreator.findEligibleAdvisors 模板方法
# | \—-AnnotationAwareAspectJAutoProxyCreator.findCandidateAdvisors
# | | \—-AbstractAdvisorAutoProxyCreator.findCandidateAdvisors
# | | | \—-BeanFactoryAdvisorRetrievalHelper.findAdvisorBeans 寻找XML配置文件中配置的Advisor
# | | \—-BeanFactoryAspectJAdvisorsBuilder.buildAspectJAdvisors 寻找AspectJ注解对应的Advisor
# | \—-AbstractAdvisorAutoProxyCreator.findAdvisorsThatCanApply 删除不匹配的Advisor
# | \—-AopUtils.findAdvisorsThatCanApply
# | \—-AopUtils.canApply 判断Pointcut和当前类是否匹配
# | \—-MethodMatcher.matches
# | \—-IntroductionAwareMethodMatcher.matches
# \—-AbstractAutoProxyCreator.createProxy 利用前一步生成的intercetpors创建代理
# \—-new ProxyFactory
# \—-AbstractAutoProxyCreator.buildAdvisors 适配成Advisor
# | \—-DefaultAdvisorAdapterRegistry.wrap
# \—-ProxyFactory.getProxy
