二、修改 UserServiceImpl 的 getUserByCodePassword 的方法

修改如下

    @Override    public User getUserByCodePassword(User u) {        //1.根据登录名称查询登录用户        //2.判断用户是否存在。不存在，抛出异常，提示：用户名不存在        //3.判断用户登录密码是否正确。不正确，抛出异常，提示：密码错误        //4.返回查询到的用户对象        User existU = ud.getByUserCode(u.getUser_code());        if(existU==null){            throw new RuntimeException("用户名不存在");        }        if(!existU.getUser_password().equals(u.getUser_password())){            throw new RuntimeException("密码错误");        }        return existU;    }

三、UserAction修改

整体修改的UserAction如下

package com.qwm.ssh_crm.web.action;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;import com.qwm.ssh_crm.domain.User;import com.qwm.ssh_crm.service.UserService;/** * @author：qiwenming * @date：2017/11/1 0001   23:37 * @description： */public class UserAction extends ActionSupport implements ModelDriven<User>{    private User user = new User();    private UserService userService;    public String login() throws Exception{        //1.调用Service执行登录逻辑        User u = userService.getUserByCodePassword(user);        //2.将返回的user对象放入到session域        ActionContext.getContext().getSession().put("user",u);        //3.重定向到项目首页        return "toHome";    }    public void setUserService(UserService userService) {        this.userService = userService;    }    @Override    public User getModel() {        return user;    }}

---

四、修改 struts.xml的配置

修改 UserAction的配置，如下

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"        "http://struts.apache.org/dtds/struts-2.5.dtd"><struts>    <!-- 配置动态方法调用是否开启常量  默认是关闭的,需要开启-->    <constant name="struts.enable.DynamicMethodInvocation" value="true"/>    <!--       struts.objectFactory = spring    将action的创建交给spring容器        struts.objectFactory.spring.autoWire = name spring负责装配Action依赖属性 默认已经打开了-->    <constant name="struts.objectFactory" value="spring"/>    <package name="crm1" namespace="/" extends="struts-default">        <!--全局允许方法调用-->        <global-allowed-methods>regex:.*</global-allowed-methods>        <global-exception-mappings>            <exception-mapping result="error" exception="java.lang.RuntimeException"></exception-mapping>        </global-exception-mappings>        <!--class属性值，来自applicationContext.xml 中 Action的配置-->        <action name="UserAction_*" class="userAction" method="{1}">            <result name="toHome" type="redirect">/index.html</result>            <result name="error">/login.jsp</result>        </action>    </package></struts>
