Spring Bean Life cycle

Life cycle of an instance from a bean

By ApplicationContext

1. Create an instance
2. Set property of the instance
3. *BeanNameAware(Interface) implement to call setBeanName, pass you BeanName
4. *BeanFactoryAware(Interface) implement to  call setBeanFactory, pass you BeanFactory
5. *ApplicationContextAware(Interface) implement to  call, pass you ApplicationContext
6. *BeanPostProcessor(Interface) postProcessBeforeInitialization(function), any one or more Bean class to implement to call, like filter, remember to return the object. AOP
7. *InitializingBean(Interface) implement to call afterPropertiesSet
8. *customized function defined by "init-method" in <bean> config, or @PostConstruct
9. *BeanPostProcessor(Interface) postProcessAfterInitialization(function)
10. Instance Ready to use
11. Spring Container closing
12. *DisposableBean(Interface) implement to call destroy
13. *customized function defined by "destroy-method" in <bean> config, or @PreDestroy

Most common steps: 1,2,6, 9,10,11

* steps: optional
Suggested to use customized function since it's not bonded to Spring

By BeanFactory

Do NOT have ApplicationContext and BeanPostProcessor

Only have 1,2,3,4,7,8,10,11,12,13
