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>

<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;
if(len==0||phone==null){

$("#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();
return false;
}
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，

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脚本之家。
