前言

本章分享的是登录不同的账号根据不同的权限进入后台看到不同的界面。

一、分析权限划分

用户表

角色权限中间表


最终整理出表格

二、编写登录功能

先边写登录进入后台的功能

用户实体类

package com.meng.entity;public class User {private long id;private String name;private String pwd;private int type;public long getId() {return id;}public void setId(long id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public int getType() {return type;}public void setType(int type) {this.type = type;}public User(long id, String name, String pwd, int type) {super();this.id = id;this.name = name;this.pwd = pwd;this.type = type;}public User() {super();}@Overridepublic String toString() {return "User [id=" + id + ", name=" + name + ", pwd=" + pwd + ", type=" + type + "]";}}

登录方法

package com.meng.dao;import java.util.List;import com.meng.entity.User;
import com.meng.util.BaseDao;
import com.meng.util.PageBean;
import com.meng.util.StringUtils;public class UserDao extends BaseDao<User>{
//	登录public List<User> list(User user,PageBean pageBean) throws Throwable {  String sql = "select * from t_easyui_user where true ";String name = user.getName();String pwd = user.getPwd();if (StringUtils.isNotBlank(name)) {sql += " and name = '"+name+"'";}if (StringUtils.isNotBlank(pwd)) {sql += " and pwd = '"+pwd+"'";}return super.executeQuery(sql,pageBean,User.class);}}

Action

package com.meng.web;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import com.meng.dao.UserDao;
import com.meng.entity.User;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriven;public class UserAction extends ActionSupport implements ModelDriven<User> {private User user=new User();private UserDao userDao=new UserDao();@Overridepublic User getModel() {// TODO Auto-generated method stubreturn user;}public String login(HttpServletRequest req, HttpServletResponse resp) {try {User current = this.userDao.list(user,null).get(0);if(current==null) {return "login";}req.getSession().setAttribute("surrent", current);} catch (Throwable e) {// TODO Auto-generated catch blocke.printStackTrace();return "login";} return "main";}}

配置xml

<action path="/user" type="com.meng.web.UserAction"><forward name="login" path="/login.jsp" redirect="false" /><forward name="main" path="/bg/main.jsp" redirect="false" /></action>

测试结果

测试后能顺利跳转后台

下章更新权限划分代码以及效果！
