Customize MVC project login registration and tree menu

Easyui and mvc project 1_ Login registration permission tree display

One 、 Sign in and register

Import tomcat And what the project needs jar Package and previously written tool classes

Set up the database User Corpses ( user )

package com.mjx.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 + "]";
	}
	
	

}

Write login and Registered dao Method

package com.mjx.dao;

import java.util.List;

import com.mjx.entity.RolePermission;
import com.mjx.entity.User;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;

public class UserDao extends BaseDao<User> {
	

	//  land 
	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);
	}

	//  register 
	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" });

	}


	

}

Write UserAction

package com.mjx.web;

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

import com.mjx.dao.UserDao;
import com.mjx.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();

	@Override
	public User getModel() {
		// TODO Auto-generated method stub
		return user;
	}

	//  Sign in 
	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";
		}
		//  As long as the database has this user , Just jump to the main interface 
		return "main";
	}

	//  register 
	public String register(HttpServletRequest req, HttpServletResponse resp) {
		try {
			userDao.add(user);
			req.setAttribute("msg", " Wrong user name or password ");
		} catch (Exception e) {
			e.printStackTrace();
			return "toRegister";
		}

		//  If the registration is successful , Jump to the login screen 
		return "toLogin";
	}
}

modify xml file , Corresponding to the page to jump

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

</config>

And main.js

$(function(){
	$("#bookMenus").tree({
		url:$("#ctx").val()+"/Permission.action?methodName=tree"
	})
})

Running results ：
