Spring AOP时序图

proxyFactory.addAdvisors(advisors);

method.invoke()

AbstractXmlApplicationContext

getInstance

AbstractAutoProxyCreator。postProcessBeforeInstantiation()主要是往advisedBeans里面添加advisor的beanName注意shouldSkip() -> AbstractAdvisorAutoProxyCreator.findCandidateAdvisors提前初始化Advisor的bean(populateBean属性pointcut，pointcut是prototype的)而Advice的bean是在warpIfNecessary() -> findCandidateAdvisors() -> advisor.getAdvice()的时候初始化的

AbstractAutowireCapableBeanFactory

findAdvisorBeans()

doCreateBean()

BeanFactoryAdvisorRetrievalHelper

postProcessAfterInitialization()

在获得inteceptor的list之后如果list是空的，则直接通过method.invoke()调用代理对象的方法。如果list不是空的，则通过ReflectiveMethodInvocation递归调用inteceptor和 以及最后调用method.invoke()（注意AfterReturning和AfterThrowingAdvice）

getAdvicesAndAdvisorsForBean()

createAopProxy(this)

applyBeanPostProcessorsAfterInitialization()

ReflectiveMethodInvocation

getInterceptors()

initializeBean()

applyBeanPostProcessorsBeforeInitialization()

ProxyCreatorSupport

createProxy()

getProxy(classLoader)

if advisor is PointcutAdvisor

createAopProxy()

new proxyFactory.getProxy(getProxyClassLoader())

根据Advisor的beanName，通过beanFactory.getBean()来获得对应Advisor的Bean

如果用了aop:advisor或者aop:advice，则通过ConfigBeanDefinitionParser来parsePointcut，parseAdvisor，parseAspect，然后registerBeanDefinition..(之前一步会configureAutoProxyCreator，即注册internalAutoProxyCreator到beanDefinition，internalAutoProxyCreator是AspectJAwareAdvisorAutoProxyCreator，是一个BeanPostProcessor)。

wrapIfNecessary()

if (this.currentInterceptorIndex == this.interceptorsAndDynamicMethodMatchers.size() - 1) {   return invokeJoinpoint();  }  Object interceptorOrInterceptionAdvice =    this.interceptorsAndDynamicMethodMatchers.get(++this.currentInterceptorIndex);return ((MethodInterceptor) interceptorOrInterceptionAdvice).invoke(this);如果有一个MethodBeforeAdvice和一个MethodAfterAdvice先调用MethodBeforeAdvice.before()，然后调用MethodAfterAdvice之前先进行proceed，这时候this.currentInterceptorIndex == this.interceptorsAndDynamicMethodMatchers.size() - 1)，调用invokeJoinpoint()，即method.invoke()调用真正方法，返回之后调用MethodAfterAdvice.afterReturning()方法，完成切入

AbstractAutoProxyCreator

AdvisedSupport

beanNamesForTypeIncludingAncestors()找到Advisor的beanName

postProcessBeforeInstantiation()

GlobalAdvisorAdapterRegistry.getInstance()单例模式，生成DefaultAdvisorAdapterRegistry该类构造函数：registerAdvisorAdapter(new MethodBeforeAdviceAdapter());registerAdvisorAdapter(new AfterReturningAdviceAdapter());registerAdvisorAdapter(new ThrowsAdviceAdapter());将这三个AdvisorAdapter添加到ArrayList类型的adapters里面这些adapter适配器的实现为AOP的Advice提供了编织能力

loadBeanDefinitions()

postProcessBeforeInitialization()

DefaultAdvisorChainFactory

findCandidateAdvisors()

findEligibleAdvisors()

extendAdvisors()

SpringAOP：ProxyConfig生成代理类的父类。下面实现类有AdvisedSupport，AbstractAutoProxyCreatorAdvisedSupport同时实现了Advised，来对Advisor进行add或者remove-- ProxyFactory是主要是实现类-- AspectJProxyFactory主要提供了PointCut切入点，ProxyFactory则是对所有方法生效。AbstractAutoProxyCreator则是最主要创建proxy的类Advised - 包含Advisor和Advice是AdvisedSupport，ProxyFactory，AspectJProxyFactory的父类Advice - 通知，有前置通知，后置通知等等。（Inteceptor的实现类MethodInteceptor也是Advice）Pointcut - 切入点Advisor - 通知+切入点的适配器，可以定位到PointCut所指向的方法（AspectJExpressionPointcutAdvisor）Advice也能包装成Advisor

createBean()

ProxyFactory

getInterceptors()如果advice是MethodInteceptor，则直接加入list如果不是则通过上面new的三个AdvisorAdapter，对advice进行适配，比如MethodBeforeAdvice会被适配成MethodBeforeAdviceInterceptor，然后加入list

BeanFactoryUtils.beanNamesForTypeIncludingAncestors()

AbstractAutoProxyCreator。postProcessBeforeInitialization()没做任何处理

getAopProxyFactory()

resolveBeforeInstantiation()

Pointcut切点进行matches的匹配过程，如果match的，则需要增强
