Spring常用的扩展类主要有:
- BeanFactoryPostProcessor Spring允许在Bean创建之前，读取Bean的元属性，并根据自己的需求对元属性进行改变，比如将Bean的scope从singleton改变为prototype
- BeanPostProcessor ,在每个bean的初始化前后调用
- InstantiationAwareBeanPostProcessor ,继承自
BeanPostProcessor,新增了三个方法,可在Bean实例化前后做一些操作- BeanNameAware、ApplicationContextAware 和 BeanFactoryAware 可以获取容器上下文,从而操作bean等,经常做Spring工具类.
- InitializingBean 在属性设置完毕后做一些自定义操作
- DisposableBean 在关闭容器前做一些操作
- FactoryBean,在初始化的时候调用getObject方法，可以返回代理类，aop就是这样实现的
