本文實例為大家分享了Spring MVC mybatis實現注冊登錄功能的具體代碼，供大家參考，具體內容如下

前期準備：

如下圖所示，準備好所需要的包

新建工程，導入所需要的包，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"

 </init-param>

 </filter-mapping>
 <!-- 前端控制器 -->
<servlet>
 <servlet-name>spring</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <!-- 在tomcat啟動時初始化servlet的優先級，這個數字只能整數，正整數才會初始化servlet -->
 <load-on-startup>1</load-on-startup>
 <init-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>/WEB-INF/config/spring.xml</param-value>
 </init-param>
</servlet>
<servlet-mapping>
 <servlet-name>spring</servlet-name>
 <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

<?xml version="1.0" encoding="UTF-8"?>

配置好數據庫信息

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，還有所需要的操作數據庫的語句：

<?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">

 <!-- 用戶注冊的判斷 -->
 <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>
 
 <!-- 用戶名唯一性的判斷 -->
 <select id="judgeUser" parameterType="String" resultType="com.register.vo.User">
 select phone_mobile from user_login where phone_mobile=#{phone_mobile}
 </select>
 
 <!-- 用戶登錄的判斷返回一個user給service處理 -->
 <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>

前端準備工作

我做的一個簡單的注冊登錄的頁面，在頁面中對表單進行了第一層的判斷，然后在后端又寫了第二層驗證。

登陸頁面如下

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

 <script src="<%=basePath%>/js/My97DatePicker/WdatePicker.js" ></script> 
 <script type="text/javascript">
// 用戶名合法性的判斷
 $(function(){
 $("#phone_number").blur(function(){
 var phone = $("#phone_number").val();
 var len = $("#phone_number").val().length;
 if(len==0||phone==null){
 $("#userNameError").html("手機號不能為空！");
 $("#loginFrm").attr("onsubmit","return false");
 }
 });
 });
 
// 密碼合法性的判斷
 $(function(){
 $("#pwd").blur(function(){
 var len = $("#pwd").val().length;
 if(len==0){
 $("#pwdError").html("密碼不能為空！");
 $("#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(); 
  return false; 
 }
  fr.submit();
 }
 </script>
 <body>
 <div class="page-container">

頁面中對手機號進行了驗證，而且能夠與后臺進行交互，判斷數據庫中是否已有此手機號，頁面所需的js文件和css配置會在以下給出，

進入正題

數據庫中包含用戶手機號，用戶密碼，以及注冊信息，和生成的唯一識別碼

以下是用戶的實體類

package com.register.vo;

import java.util.Date;

public class User {
private int id;
private String phone_mobile;//用戶手機號
private String login_password;//用戶登錄密碼
private Date register_time;//用戶注冊日期
private String user_code;//用戶唯一識別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;
}
//對用戶數據進行封裝
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;
}

}

下面這一步是比較重要的一步，Controller類，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;


//讓控制器成為一個bean
@Controller
//這個控制器是接受user_reg頁面傳過來的參數去操作數據庫
public class UserController {
 @Autowired
 private SqlSession sqlSession;
 @Autowired
 private UserService us;
 @Autowired
 private HttpServletRequest req;
 @RequestMapping("/userReg.action")
 //jsp頁面通過userReg.action找到這個方法
 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());
  
 //判斷頁面傳回的數據要求
 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";
 }
 
 //獲取當前注冊時間
 Date date = new Date();
 DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
 map.put("register_time", df.format(date));
 
 //生成唯一識別碼
 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);
 
 //將數據添加到數據庫中
 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";
 }


 //處理用戶名唯一性的判斷         
 @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;
 }
 
 //用戶登錄的判斷
 @RequestMapping("/userLogin.action")
 public String userLogin(String phone_mobile,String login_password){
 //對頁面傳回的值進行二次判斷
 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);
 
 //查到用戶了，執行登錄成功的操作
 if(u!=null){
 req.getSession().setAttribute("u", u);
 return "pages/user-login-ok.jsp";
 }else{
 return "pages/user-login-no.jsp";
 }
 }
 //用戶退出銷毀session 跳轉到登錄頁
 @RequestMapping("/userExit.action")
 public String userExit(HttpSession session){
 session.invalidate();
 return "index.jsp";
 }
}

UserService類：

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;
 }
}

注入測試類：

package com.register.util;

import org.springframework.stereotype.Controller;

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

}

OK，到這里已經基本差不多了，但是這里邊所給的代碼并不完整，為了方便大家相互交流學習，這是源碼以及數據庫文件，
鏈接：注冊登錄功能，想要參考源碼的可以自己下載。

以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持億速云。
