Question
Explain bean life cycle in spring framework?
Answers
The spring container finds the bean’s definition from the XML file and instantiates the bean.

• Spring populates all of the properties as specified in the bean definition (DI).

• If the bean implements BeanNameAware interface, spring passes the bean’s id to setBeanName() method.

• If Bean implements BeanFactoryAware interface, spring passes the beanfactory to setBeanFactory() method.

• If there are any bean BeanPostProcessors associated with the bean, Spring calls postProcesserBeforeInitialization() method.

• If the bean implements IntializingBean, its afterPropertySet() method is called. If the bean has init method declaration, the specified initialization method is called.

• If there are any BeanPostProcessors associated with the bean, their postProcessAfterInitialization() methods will be called.

• If the bean implements DisposableBean, it will call the destroy() method.   Your Comment
