# SpringAOP #

SpringAOP大致执行过程

AbstractAutowireCapableBeanFactory

> 1.  createBean()//->AbstractAutowireCapableBeanFactory\#doCreateBean()
> 2.  doCreateBean()//->AbstractAutowireCapableBeanFactory\#initializeBean()
> 3.  initializeBean()//-AbstractAutowireCapableBeanFactory\#applyBeanPostProcessorsAfterInitialization()
> 4.  applyBeanPostProcessorsAfterInitialization()//->AbstractAutoProxyCreator\#postProcessAfterInitialization()

AbstractAutoProxyCreator

> 1.  postProcessAfterInitialization()//->AbstractAutoProxyCreator\#wrapIfNecessary()
> 2.  wrapIfNecessary()//->AbstractAutoProxyCreator\#getAdvicesAndAdvisorsForBean()  
>     注：由子类AbstractAdvisorAutoProxyCreator实现//->AbstractAutoProxyCreator\#createProxy()  
>     createProxy()//->ProxyFactory\#getProxy()

AbstractAutoProxyCreator

> 1.  getAdvicesAndAdvisorsForBean()//->AbstractAutoProxyCreator\#findEligibleAdvisors()
> 2.  findEligibleAdvisors()//->AbstractAutoProxyCreator\#sortAdvisors()
> 3.  sortAdvisors()//->AnnotationAwareOrderComparator\#sort()

AbstractAutoProxyCreator

> 1.  createProxy()//->ProxyCreatorSupport\#getProxy()

ProxyFactory

> 1.  getProxy()//->ProxyCreatorSupport\#createAopProxy()

DefaultAopProxyFactory

> 1.  createAopProxy()//->返回一个AopProxy对象给AbstractAutoProxyCreator\#createProxy()

JdkDynamicAopProxy

> 1.  invoke()//->AdvisedSupport\#getInterceptorsAndDynamicInterceptionAdvice()

# SpringIOC #

SpringDI大致调用过程

AbstractBeanFactory

> 1.  getBean() //->AbstractBeanFactory\#getBean() //从Bean工厂获取一个实例Bean
> 2.  doGetBean()//->AbstractBeanFactory\#doGetBean()，//返回一个指定Bean的实例，如果没有，则调用createBean

AbstractAutowireCapableBeanFactory

> 1.  createBean()//->AbstractAutowireCapableBeanFactory\#createBean() //创建一个Bean实例，用于doGetBean方法
> 2.  createBeanInstance()//->AbstractAutowireCapableBeanFactory\#createBeanInstance() //使用适当的创建策略为指定的Bean创建实例
> 3.  instantiateBean()//->AbstractAutowireCapableBeanFactory\#instantiateBean() //初始化给定的Bean实例
> 4.  populateBean()//->AbstractAutowireCapableBeanFactory\#populateBean() //对Bean属性依赖注入进行处理
> 5.  applyPropertyValues()//->AbstractAutowireCapableBeanFactory\#applyPropertyValues() //对属性进行注入

BeanDefinitionValueResolver

> 1.  resolveValueIfNecessary()//->BeanDefinitionValueResolver\#resolveValueIfNecessary() //转换属性值

AbstractPropertyAccessor

> 1.  setPropertyValues()//->AbstractPropertyAccessor\#setPropertyValues() //进行我们的属性依赖注入

AbstractNestablePropertyAccessor

> 1.  processKeyedProperty() or processLocalProperty() //设置本地属性或者Key属性
