书写顺序即为调用顺序

---

BeanDefinitionRegistryPostProcessor   ->postProcessBeanFactory(先调用BeanDefinitionRegistry的Factory后置处理器)

BeanFactoryPostProcessor ->postProcessBeanFactory(后调用普通的Factory后置处理器)

调用入口application ->refresh：

invokeBeanFactoryPostProcessors(beanFactory);

---

调用入口application ->refresh：

onRefresh();

getBean():

BeanPostProcessor ->实例化前后

postProcessBeforeInitialization(The bean will already be populated with propertyvalues)

postProcessAfterInitialization(The bean will already be populated with propertyvalues)

InstantiationAwareBeanPostProcessor

postProcessBeforeInstantiation ->动态代理

postProcessAfterInstantiation (Modify the state of the bean before properties are set)-> populateBean

---

postProcessPropertyValues(Before the factory applies them To the given bean)->populateBean ->AutowiredAnnotationBeanPostProcessor(autowire自动注入)

---

SmartInitializingSingleton->afterSingletonsInstantiated (所有non-lazy 初始化之后调用)

调用入口application ->refresh：

//Instantiateallremaining(non-lazy-init)singletons.

finishBeanFactoryInitialization(beanFactory);
