1. BeanFactoryPostProcessor调用（见AbstractApplicationContext.refresh）：

>> 创建DefaultListableBeanFactory --> loadBeanDefinitions

1）BeanDefinitionRegistryPostProcessor.postProcessBeanDefinitionRegistry（编码注册）

2）BeanDefinitionRegistryPostProcessor.postProcessBeanDefinitionRegistry（配置注册）：PriorityOrdered排序 --> Ordered排序 --> 无序

3）BeanFactoryPostProcessor.postProcessBeanFactory（编码注册）：BeanDefinitionRegistryPostProcessor --> BeanFactoryPostProcessor

4）BeanFactoryPostProcessor.postProcessBeanFactory（配置注册）：PriorityOrdered排序 --> Ordered排序 --> 无序

 

2. BeanPostProcessor注册：

1）PriorityOrdered排序 --> Ordered排序 --> 无序

2）MergedBeanDefinitionPostProcessor

 

3. BeanPostProcessor调用（见DefaultListableBeanFactory.createBean）：

1）InstantiationAwareBeanPostProcessor.applyBeanPostProcessorsBeforeInstantiation（resolveBeforeInstantiation）

>> 获取bean --> 6

>> createBeanInstance（默认：CglibSubclassingInstantiationStrategy.instantiate） --> 2

2）MergedBeanDefinitionPostProcessor.postProcessMergedBeanDefinitioInstantiationAwareBeanPostProcessor

3）InstantiationAwareBeanPostProcessor.postProcessAfterInstantiation

>> autowireByName / autowireByType

4）InstantiationAwareBeanPostProcessor.postProcessPropertyValues

>> applyPropertyValues

5）BeanPostProcessor.postProcessBeforeInitialization（@postConstruct）

>> InitializingBean.afterPropertiesSet --> invokeInitMethod（init-method ）

6）BeanPostProcessor.postProcessAfterInitialization

>> 单实例（容器初始化完成）：SmartInitializingSingleton.afterSingletonsInstantiated

 

4. 应用

1）BeanFactoryPostProcessor

2）BeanPostProcessor：ApplicationContextAwareProcessor、InitDestroyAnnotationBeanPostProcessor、AutowiredAnnotationBeanPostProcessor、AOP
