注意：在webroot节点下建立一个login.jsp才能找到。

Struts.xml配置

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"    "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <constant name="struts.devMode" value="false" />    <!-- package：用来统一管理action -->     <package name="SSHdemo" extends="struts-default" namespace="/">        <!-- 用户模块的Action -->        <action name="user_*" class="userAction" method="{1}">            <result name="loginSuccess">index.jsp</result>                      </action>    </package></struts>

注意：action标签的class属性，与spring结合后要写成spring中bean的名称name。

applicationContext.xml

3.登录实例编写

Action层：UserAction

/** * 用户模块Action的类 *  * @author xiao *  */public class UserAction extends ActionSupport implements ModelDriven<User> {    //模型驱动使用的对象    private User user=new User();    public User getModel(){        return user;    }    // 注入UserService    private UserService userService;    public void setUserService(UserService userService) {        this.userService = userService;    }    /**     * 登陆     */    public String login(){        User existUser=userService.login(user);        if(existUser==null){            //登陆失败            this.addActionError("登陆失败：用户名或密码错误用户未激活！");            return LOGIN;        }else {            //登陆成功            //将用户的信息存入session中            ServletActionContext.getRequest().getSession().setAttribute("existUser", existUser);            //页面跳转            return "loginSuccess";        }    }}
