Spring MVC+mybatis实现注册登录功能

本文实例为大家分享了Spring MVC mybatis实现注册登录功能的具体代码，供大家参考，具体内容如下

前期准备：

如下图所示，准备好所需要的包

新建工程，导入所需要的包，在web.xml中配置好所需要的，如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

 <url-pattern>*.action</url-pattern>
</servlet-mapping>
 <welcome-file-list>
 <welcome-file>index.jsp</welcome-file>
 </welcome-file-list>
</web-app>

配置好如下文件spring.xml

配置好数据库信息

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/cheshangbao?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useOldAliasMetadataBehavior=true
username=root
password=admin

另外，还有所需要的操作数据库的语句：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- sql 映射文件 -->

<mapper namespace="com.register.dao">

 <!-- 用户注册的判断 -->
 <insert id="addUser" parameterType="map">
 insert into user_login (phone_mobile,login_password,register_time,user_code) values(#{phone_mobile},#{login_password},#{register_time},#{user_code})
 </insert>

 <!-- 用户名唯一性的判断 -->
 <select id="judgeUser" parameterType="String" resultType="com.register.vo.User">
 select phone_mobile from user_login where phone_mobile=#{phone_mobile}
 </select>

 <!-- 用户登录的判断返回一个user给service处理 -->
 <select id="userLogin" parameterType="map" resultType="com.register.vo.User">
 select phone_mobile,login_password from user_login where phone_mobile=#{phone_mobile} and login_password=#{login_password}
 </select>
</mapper>

前端准备工作

我做的一个简单的注册登录的页面，在页面中对表单进行了第一层的判断，然后在后端又写了第二层验证。

登陆页面如下

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
 <base href="<%=basePath%>">

 <script type="text/javascript">
// 用户名合法性的判断
 $(function(){
 $("#phone_number").blur(function(){
 var phone = $("#phone_number").val();
 var len = $("#phone_number").val().length;

 $("#loginFrm").attr("onsubmit","return false");
 }
 });
 });

// 密码合法性的判断
 $(function(){
 $("#pwd").blur(function(){
 var len = $("#pwd").val().length;
 if(len==0){
 $("#pwdError").html("密码不能为空！");
 $("#loginFrm").attr("onsubmit","return false");
 }
 })
 })

 function check(){
 fr=document.form1;
 if(fr.phone_mobile.value==""){
  fr.phone_mobile.focus();
  return false;
 }
 if((fr.login_password.value!="")){
  fr.pwd1.focus();

  fr.submit();

页面中对手机号进行了验证，而且能够与后台进行交互，判断数据库中是否已有此手机号，页面所需的js文件和css配置会在以下给出，

进入正题

数据库中包含用户手机号，用户密码，以及注册信息，和生成的唯一识别码

以下是用户的实体类

package com.register.vo;

import java.util.Date;

public class User {
private int id;
private String phone_mobile;//用户手机号
private String login_password;//用户登录密码
private Date register_time;//用户注册日期
private String user_code;//用户唯一识别ID

public User(int id, String phone_mobile, String login_password, Date register_time,
 String user_code) {
 super();
 this.id = id;
 this.phone_mobile = phone_mobile;
 this.login_password = login_password;
 this.register_time = register_time;
 this.user_code = user_code;
}

public User(String phone_mobile, String login_password, Date register_time, String user_code) {
 super();
 this.phone_mobile = phone_mobile;
 this.login_password = login_password;
 this.register_time = register_time;
 this.user_code = user_code;
}
public User() {
}

public int getId() {
 return id;
}
//对用户数据进行封装
public void setId(int id) {
 this.id = id;
}

public String getPhone_mobile() {
 return phone_mobile;
}

public void setPhone_mobile(String phone_mobile) {
 this.phone_mobile = phone_mobile;
}

public String getLogin_password() {
 return login_password;
}

public void setLogin_password(String login_password) {
 this.login_password = login_password;
}

public Date getRegister_time() {
 return register_time;
}

public void setRegister_time(Date register_time) {
 this.register_time = register_time;
}

public String getUser_code() {
 return user_code;
}

public void setUser_code(String user_code) {
 this.user_code = user_code;
}

}

下面这一步是比较重要的一步，Controller类， 如下所示

package com.register.controller;
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.ibatis.session.SqlSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.register.service.UserService;
import com.register.vo.User;

//让控制器成为一个bean
@Controller
//这个控制器是接受user_reg页面传过来的参数去操作数据库
public class UserController {
 @Autowired
 private SqlSession sqlSession;
 @Autowired
 private UserService us;
 @Autowired
 private HttpServletRequest req;
 @RequestMapping("/userReg.action")
 //jsp页面通过userReg.action找到这个方法
 public String userReg(User user){
 Map<String,Object> map = new HashMap<String, Object>();
 map.put("phone_mobile", user.getPhone_mobile());
 map.put("login_password", user.getLogin_password());

 //判断页面传回的数据要求
 Pattern pattern = Pattern.compile("^((13[0-9])|(15[^4,\\D])|(18[01236789]))\\d{8}$");
 Matcher matcher = pattern.matcher(user.getPhone_mobile());
 if(user.getPhone_mobile()==null || user.getLogin_password()==null || !matcher.matches()){
 return "index.jsp";
 }

 //获取当前注册时间
 Date date = new Date();
 DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
 map.put("register_time", df.format(date));

 //生成唯一识别码
 String s = UUID.randomUUID().toString();
 String user_code = s.substring(0,8)+s.substring(9,13)+s.substring(14,18)+s.substring(19,23)+s.substring(24);
 map.put("user_code", user_code);

 //将数据添加到数据库中
 int a = sqlSession.insert("com.register.dao.addUser",map);

 req.setAttribute("phone_mobile", user.getPhone_mobile());
 req.setAttribute("login_password", user.getLogin_password());
 return "pages/register_success.jsp";
 }

 //处理用户名唯一性的判断
 @RequestMapping("/userJudge.action")
 @ResponseBody
 public User userJudge(String phone_mobile) {
 User u = sqlSession.selectOne("com.register.dao.judgeUser",phone_mobile);
 System.out.println(u.getPhone_mobile());
 return u;
 }

 //用户登录的判断
 @RequestMapping("/userLogin.action")
 public String userLogin(String phone_mobile,String login_password){
 //对页面传回的值进行二次判断
 Pattern pattern = Pattern.compile("^((13[0-9])|(15[^4,\\D])|(18[01236789]))\\d{8}$");
 Matcher matcher = pattern.matcher(phone_mobile);
 if(phone_mobile==null || login_password==null || !matcher.matches()){
 return "pages/user-login-no.jsp";
 }

 User u = us.userLogin(phone_mobile, login_password);

 //查到用户了，执行登录成功的操作
 if(u!=null){
 req.getSession().setAttribute("u", u);
 return "pages/user-login-ok.jsp";
 }else{
 return "pages/user-login-no.jsp";
 }
 }
 //用户退出销毁session 跳转到登录页
 @RequestMapping("/userExit.action")
 public String userExit(HttpSession session){
 session.invalidate();
 return "index.jsp";
 }
}

UserService类：

package com.register.service;

import java.util.HashMap;
import java.util.Map;

import org.apache.ibatis.session.SqlSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.register.vo.User;

@Service
public class UserService {
 @Autowired
 private SqlSession sqlSession;
 public User userLogin(String phone_mobile,String login_password){
 Map<String,Object> map = new HashMap<String, Object>();
 map.put("phone_mobile",phone_mobile);
 map.put("login_password", login_password);
 User u = sqlSession.selectOne("com.register.dao.userLogin",map);
 return u;
 }
}

注入测试类：

package com.register.util;

import org.springframework.stereotype.Controller;

@Controller
public class TestUtil {
 public void a(){
 System.out.println("注入成功！");
 }

}

OK，到这里已经基本差不多了，但是这里边所给的代码并不完整，为了方便大家相互交流学习，这是源码以及数据库文件，
链接：注册登录功能，想要参考源码的可以自己下载。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我们。
