SSH 框架整合（maven版本 xml配置方式）

如何整合Struts2 Hibernate 和Spring 首先你必须了解三个框架是如何独立运行的：
代码下载：http://download.csdn.net/detail/zhanglinlang/9775160

Struts2 是通过在web.xml 中 Filter拦截器来启动自己的核心类StrutsPrepareAndExecuteFilter，完成事件的分发。

Spring 是通过 在web.xml 注册监听器来监听ContextLoaderListener，监听web应用的启动事件来完成自己的框架启动工作。

Hibernate 是通过创建SessionFactory工厂手动加载配置文件来完成启动工作，Hibernate是可以通过代码创建SessionFactory，就可以交给Spring通过ioc来控制该类的实例化。

下面就是整合代码：目录结构如下

首先在resource目录下创建 config目录方便管理：
首先配置

　　整合细节知识点(了解)：
Struts2 和 Spring整合：就是将action的创建交由Spring管理。配置文件中class只需要配置Spring中bean的id就可以。

?

1	<action name="userAction" class="SpringBeanId" />

　　

Hibernate和Spring整合：
1、创建连接池的对象交由spring管理
2、Spring提供了SessionFactory的封装类LocalSessionFactory，配置该类，并将数据源配置给它。
3、配置Spring的HibernateTemplate，将SessionFactory配置给他。替代session完成数据操作。
4、spring 事务管理配置，替代Hibernate事务管理
