Following is sequence of a bean LIFECYCLE in Spring:

Instantiate - First the spring container finds the bean's definition from the XML file and instantiates the bean..

Populate PROPERTIES - Using the dependency injection, spring populates all of the properties as specified in the bean definition..

Set Bean Name - If the bean implements BeanNameAware interface, spring passes the bean's id to setBeanName() method.

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

PRE Initialization - Also called POSTPROCESS of bean. If there are any bean BeanPostProcessors associated with the bean, Spring calls postProcesserBeforeInitialization() method.

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

Post Initialization - If there are any BeanPostProcessors associated with the bean, their postProcessAfterInitialization() METHODS will be called.

Ready to use - Now the bean is ready to use by the application.

Destroy - If the bean implements DisposableBean , it will call the destroy() method .
