一。加入struts2
1.在pom.xml中加入struts2的依赖
2.在web.xml中加入过滤器
二。加入spring框架,整合spring+struts2
1.加入spring的依赖,和struts与spring整合的依赖
2.在web.xml中加入spring监听,以及告诉监听spring的配置文件
3.struts.xml文件修改
4.appliaction.xml也就是spring核心配置文件
5.各层用注解完成依赖注入
@Repository:DAO层的注解申明
@Service:业务层注解
@Controller:控制层注解 @Controller("userAction")此处的名字要和struts.xml中Action的class属性一致
实例:整合ssh,并完成前台发送请求后台,后台返回数据到前台的过程

//如果使用spring来管理事务,一定要用getCurrentSession()来获取session
return sessionFactory.getCurrentSession();
