[JavaScript知识库]easyUI项目

一、思维导图

二、项目部署

1、在tomcat中的webapps文件中加入mvc.w

?

2、在tomcat的bin目录下运行startup.bat

3、在webapps文件中的MVC中复制文件

?

三、权限登录

商家与买家所登录看到的界面不一致

1、登录方法/注册

①、用户实体类

package com.dhm.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;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", pwd=" + pwd + ", type=" + type + "]";
	}
	
	

}

②、UserDao

package com.dhm.dao;

import java.util.List;

import com.dhm.entity.User;
import com.zking.util.BaseDao;

public class UserDao extends BaseDao<User>{
//	登录的方法，看数据库里能不能查到这个用户
	public User login(User user) throws Exception {
		String sql="select * from t_easyui_user where name='"+user.getName()+"' and pwd='"+user.getPwd()+"'";
		return super.executeQuery(sql,User.class, null).get(0);
	}
	
	
//	增加用户的方法
	public void add(User user) throws Exception {
	String sql="insert into t_easyui_user(name,pwd) values(?,?)";
	super.executeUpdate(sql, user, new String[] {"name","pwd"});
	}

	
	
	
//	public List<User> list(String sql, Class<User> clz, PageBean pageBean) throws Exception {
//
//			
//			return super.executeQuery(sql, clz, pageBean);
//		}
	
	

}

③、UserAction

package com.dhm.web;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.dhm.dao.UserDao;
import com.dhm.entity.User;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;

public class UserAction extends ActionSupport implements ModelDriver<User>{

	private User user=new User();
	private UserDao userDao=new UserDao();
	
	
	public User getModel() {
		return user;
	}
	
	/**
	 * 用户登录方法调用
	 * @param req
	 * @param resp
	 * @return
	 */
	public String login(HttpServletRequest req, HttpServletResponse resp) {
		try {
			User u = userDao.login(user);
			if(u==null) {
				return "toLogin";
			}
			req.getSession().setAttribute("cuser", u);
		} catch (Exception e) {
			e.printStackTrace();
			return "toLogin";
		}
//		只要数据库中有这个用户就跳转到主界面
		return "main";
	}
	
	
	public String register(HttpServletRequest req, HttpServletResponse resp) {
		try {
			userDao.add(user);
			req.setAttribute("msg", "用户名密码错误");
		} catch (Exception e) {
			e.printStackTrace();
			return "toRegister";
		}
//     如果注册成功，跳转登界面   
		return "toLogin";
	}
}

④、mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
	<action path="/user" type="com.dhm.web.UserAction">
		<forward name="main" path="/bg/mainTemp.jsp" redirect="false" />
		<forward name="toLogin" path="/login.jsp" redirect="true" />
		<forward name="toRegister" path="/register.jsp" redirect="false" />
	</action>
	<action path="/permission" type="com.dhm.web.PermissionAction">
	
	</action>
</config>

效果展示：

注册界面

2、树形菜单

①、Permission实体类

package com.dhm.entity;

public class Permission {
	private long id;
	private String name;
	private String description;
	private String url;
	private long pid;
	private int ismenu;
	private long displayno;
	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 getDescription() {
		return description;
	}
	public void setDescription(String description) {
		this.description = description;
	}
	public String getUrl() {
		return url;
	}
	public void setUrl(String url) {
		this.url = url;
	}
	public long getPid() {
		return pid;
	}
	public void setPid(long pid) {
		this.pid = pid;
	}
	public int getIsmenu() {
		return ismenu;
	}
	public void setIsmenu(int ismenu) {
		this.ismenu = ismenu;
	}
	public long getDisplayno() {
		return displayno;
	}
	public void setDisplayno(long displayno) {
		this.displayno = displayno;
	}
	@Override
	public String toString() {
		return "Permission [id=" + id + ", name=" + name + ", description=" + description + ", url=" + url + ", pid="
				+ pid + ", ismenu=" + ismenu + ", displayno=" + displayno + "]";
	}

	public List<TreeVo<Permission>> treePlus(String ids) throws Exception {
		List<Permission> listPermission = this.listPlus(ids);
