Bean factory implementations should support the standard bean lifecycle interfaces as far as possible. The full set of initialization methods and their standard order is:
BeanFactory的實(shí)現(xiàn)應(yīng)該盡可能支持標(biāo)準(zhǔn)的bean生命周期，以下是所以的方法的順序的依次列表
1. BeanNameAware's?? setBeanName
2. BeanClassLoaderAware's? setBeanClassLoader
3. BeanFactoryAware's?? setBeanFactory
4. ResourceLoaderAware's setResourceLoader (only applicable when running in an application context)
5. ApplicationEventPublisherAware's setApplicationEventPublisher (only applicable when running in an application context)
6. MessageSourceAware's setMessageSource (only applicable when running in an application context)
7. ApplicationContextAware's setApplicationContext (only applicable when running in an application context)
8. ServletContextAware's setServletContext (only applicable when running in a web application context)
9. postProcessBeforeInitialization methods of BeanPostProcessors
10. InitializingBean's afterPropertiesSet
11. a custom init-method definition
12. postProcessAfterInitialization methods of BeanPostProcessors
?當(dāng)關(guān)閉一個(gè)bean的時(shí)候
On shutdown of a bean factory, the following lifecycle methods apply:
1. DisposableBean's destroy
2. a custom destroy-method definition
