Aware接口
aware
adj. 知道; 意识到; 明白; 察觉到; 发觉; 发现; 对…有兴趣的; 有…意识的;
当bean实现了对应的Aware接口，BeanFactory 就会在产生这个bean的时候根据对应的Aware接口，给这个bean注入相应的属性，这样bean就能够获取外界资源的引用了.
1. BeanNameAware
public interface BeanNameAware {
void setBeanName(String name) throws BeansException;
}
继承该接口，将实现setBeanName方法，bean的实例会被注入该bean的名称。
2. ApplicationContextAware
public interface ApplicationContextAware {
void setApplicationContext(ApplicationContext applicationContext) throws BeansException;
}
获取spring上下文
3. BeanFactoryAware
获取beanFactory
4. 其他
