spring + hibernate + struts    基于注解的形式，基于xml的以后需要的话在总结

web.xml

    <!-- OpenSessionInView
        这是一个经典的过滤器，session的范围就是事务的开启和事务的结束，也就是在service中的方法执行时开启
        方法结束关闭，这就会造成延迟加载错误，因为延迟加载的时候session已经关闭了，一个方法就是关闭延迟加载
        或者修改抓取策略或者预加载，但是这就丧失了hibernate的好处，所以我们就可以做到扩大session的范围，在请求
        到来的开启session，到响应结束的时候关闭session
        -->

      <!-- Spring容器      web程序是没有main函数的，所以在web容器启动的时候就要启动spring容器
