Spring bean's life

1. Spring instantiates the bean.
2. Spring injects values and bean references into the bean's properties.
3. If the bean implements BeanNameAware, Spring passes the bean's ID to the setBeanName() method.
4. If the bean implements BeanFactoryAware, Spring calls the setBeanFactory() method, passing in the bean factory itself.
5. If the bean implements ApplicationContextAware, Spring will call the setApplicationContext() method, passing in a reference to the enclosing application context.
6. If any of the beans implement the BeanPostProcessor interface, Spring calls their postProcessBeforeInitialization() method.
7. If any beans implement the InitializingBean interface, Spring calls their afterPropertiesSet() method. Similarly, if the bean was declared with an
init-method then the specified initialization method will be called.
8. If there are any beans that implement BeanPostProcessor, Spring will call their postProcessAfterInitialization method.
9. At this point, the bean is ready to be used by the application and will remain in the application context until the application context is destroyed.
10. If any beans implement the DisposableBean interface, then Spring will call their destroy() methods. Likewise, if any bean was decalred with a destroy-method then the specified method will be called.
