Spring生命周期各种接口使用

1，BeanPostProcessor接口；
不能在POJO上面使用，需要单独找一个类进行使用；
如果在POJO上面实现了此接口，在实现了其他*Aware
接口之后，这个接口方法将不会被调用；
2, POJO实现了BeanNameAware接口；
可以与BeanPostProcessor同时使用；
3, POJO实现了BeanFactoryAware接口；
可以与BeanPostProcessor同时使用；
4, POJO实现了ApplicationContextAware接口；
可以与BeanPostProcessor同时使用；
5，POJO实现了DisposableBean接口；
可以正常调用接口的dispose()方法；
6，在bean声明部分定义的init-method
和destroy-method方法可以正常调用；
7，如果显示调用dispose()、destroy-method方法，
需要使用
AbstractApplicationContext context =
new ClassPathXmlApplicationContext("appbeans.xml");
//...
context.registerShutdownHook();

8，InitializingBean.afterPropertiesSet()方法在init-method()之前调用；

DisposableBean.dispose()方法在destroy-method()之前调用；
