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

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

AbstractAutoProxyCreator

7. getAdvicesAndAdvisorsForBean()//->AbstractAutoProxyCreator#findEligibleAdvisors()
8. findEligibleAdvisors()//->AbstractAutoProxyCreator#sortAdvisors()
9. sortAdvisors()//->AnnotationAwareOrderComparator#sort()

AbstractAutoProxyCreator

10. createProxy()//->ProxyCreatorSupport#getProxy()

ProxyFactory

11. getProxy()//->ProxyCreatorSupport#createAopProxy()

DefaultAopProxyFactory

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

JdkDynamicAopProxy

13. 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

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

BeanDefinitionValueResolver

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

AbstractPropertyAccessor

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

AbstractNestablePropertyAccessor

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