SSH整合

## 简介 ##

SSH在J2EE项目中表示了3种框架，即 Spring + Struts +Hibernate。 Struts对Model，View和Controller都提供了对应的组件。Spring是一个轻量级的控制反转(IoC)和面向切面(AOP)的容器框架，它由Rod Johnson创建。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。 Hibernate是一个开放源代码的对象关系映射框架，它对JDBC进行了非常轻量级的对象封装，可以应用在任何使用JDBC的场合，可以在Servlet/JSP的Web应用中使用，也可以在应用EJB的J2EE架构中取代CMP，完成数据持久化的重任。
