a bean`s life

a 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 set-BeanName() 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 set-ApplicationContext() method, passing in a reference to the enclosing appli-cation 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 after PropertiesSet() 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 declared with a destroy-method, then the specified method will be called.
