Spring Question

Explain Bean life cycle in Spring Bean Factory Container.

Accepted Answer

The Bean life cycle is as follows:
1. The IoC container instantiates the bean based on the XML file's definition.
2. Spring then uses dependency injection to populate all of the properties as stated in the bean definition.
3. SetBeanName() is called by the bean factory container, which takes the bean ID and requires the matching bean to implement the BeanNameAware interface.
4.The factory then calls setBeanFactory() with an instance of itself as a parameter (if BeanFactoryAware interface is implemented in the bean).
5. If a bean is associated with BeanPostProcessors, the preProcessBeforeInitialization() methods are called.
6. It will be called if an init-method is given.
7. Finally, if there are any BeanPostProcessors connected with the bean that need to be executed after instantiation, the postProcessAfterInitialization() methods will be called.
