SSH整合:    1)引入SSHjar文件    Struts核心jar    Hibernate核心jar    Spring        Core 核心功能        WEB 对web功能支持        orm 对hibernate支持        jdbc/tx jdbc支持包，事务相关包    2)配置    web.xml        初始化struts功能，spring容器    Struts.xml 配置请求路径与映射action的关系    Spring.xml IOC容器的配置        bean-base.xml【配置公用信息】        bean-dao.xml        bean.service.xml        bean-action.xml    3)开发        Entity/Dao/Service/action
