SSH2配置单详解（Struts2 Hibernate3 Spring）

    <!-- 解决hibernate延迟加载出现的问题，要放在Struts2过滤器之前 -->

    <!-- 作用：Spring管理hibernate的Session，在事务管理的类执行完后，不立刻关闭Session，

        而将Session保存在一个线程变量中，在线程退出前关闭Session；这样在整个request过程中

        始终使用一个session，也就可以在request的任何时期lazy loading数据。

        主要是为了实现hibernate的延迟加载功能 -->
