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
