Struts2.0+Spring3+Hibernate3(SSH~Demo) / 憋错料

前言：整理一些集成框架，发现网上都是一些半成品，都是共享一部分出来(确实让人很纠结)，这是整理了一份SSH的测试案例，完全可以用！

言归正传，首先强调一点首先，SSH不是一个框架，而是多个框架（struts+spring+hibernate）的集成，是目前较流行的一种Web应用程序开源集成框架，用于构建灵活、易于扩展的多层Web应用程序。

集成SSH框架的系统从职责上分为四层：表示层、业务逻辑层、数据持久层和域模块层，以帮助开发人员在短期内搭建结构清晰、可复用性好、维护方便的Web应用程序。其中使用Struts作为系统的整体基础架构，负责MVC的分离，在Struts框架的模型部分，控制业务跳转，利用Hibernate框架对持久层提供支持，Spring做管理，管理struts和hibernate。具体做法是：用面向对象的分析方法根据需求提出一些模型，将这些模型实现为基本的Java对象，然后编写基本的DAO(Data Access Objects)接口，并给出Hibernate的DAO实现，采用Hibernate架构实现的DAO类来实现Java类与数据库之间的转换和访问，最后由Spring做管理，管理struts和hibernate。
