篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了SSH整合相关的知识,希望对你有一定的参考价值。
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。
