Spring简单介绍

一.Spring提供ＩＯＣ和ＡＯＰ降低应用组件的依赖性．
   1.Spring IOC

     1.1 依赖注入有三种方式：设值方法（setter-based），基于构建器(constuctor-base),和基于接口（Interface-     base).Spring IOC目前支持前两种.

1.2.1 BeanFactory位于org.springframework.beans.factory
      1.2.2AppplicationContext位于org.springframework.context
   1.3   IOC其他方面，自定义bean属性和监听事件
  2．Spring AOP
