SSH配置

struts2.3.16.1,hibernate4.2.10final,spring3.2版本整合在一起的配置，搞了十几年java还贴这玩意有点丢人，但是搭配这几个框架着实让我忙活了一天，主要是hibernate的高版本需要spring4我不知道，这些年都在用mybatis，以前觉得hibernate特别吃内存，现在跑起来性能好像还不错，具体也没有用性能压力工具去测试。

Hibernate4以后spring貌似就不太管它了，需要自己处理事务等等操作，也没有了DaoSupport类支持，自己胡乱写的BaseDAO基础类，有点简单:

因为有JPA对象的延迟加载，所以hibernate的session改成了通过在web.xml里面定义filter去打开和关闭session，注意务必要把hibernate的opensessioninviewfitler写在struts2的filter前面，另外spring的配置参数文件中务必写上<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop> 才可以实现延迟加载。
