Bean装配顺序：
1. Bean实例化;
2. 设置属性值init properties;
3. 如果实现了BeanNameAware接口，调用setBeanName设置Bean的ID或者Name;
4. 如果实现BeanFactoryAware接口，调用setBeanFactory 设置BeanFactory;
5. 如果实现ApplicationContextAware，调用setApplicationContext设置ApplicationContext
6. 调用BeanPostProcessor的预先初始化方法postProcessBeforeInitialization;
7. 调用InitializingBean的afterPropertiesSet()方法;
8. 调用定制init-method方法(XML configuration based,Not Code based)；
9. 调用BeanPostProcessor的后初始化方法postProcessAfterInitialization;
