BeanFactoryPostProcessor (可动态维护bean属性)


set注入

BeanNameAware#setBeanName 
BeanFactoryAware#setBeanFactory 
ApplicationContextAware#setApplicationContext 


BeanPostProcessor#postProcessBeforeInitialization

@PostConstruct 注解方法
InitializingBean#afterPropertiesSet
bean xml中定义的 init-method 方法

BeanPostProcessor#postProcessAfterInitialization


@PreDestroy#preDestroy
DisposableBean#destroy



注意!!!
@PostConstruct 与 @PreDestroy 需要开启组件扫描 ,否则不会生效
