总结


前言

最近Springboot课程要求以疫情为主题的登录、注册、找回密码功能,可以自行添加一些额外的功能,这里也是记录一下做好的思路和代码。


一、SpringBoot依赖

1、pom.xml文件

Maven版本号:3.5.4

登录、注册、找回密码,需要用到邮箱验证码,要引入mail依赖,实现三分钟需要使用到redis,要引入redis依赖,前端使用thymeleaf,然后引入的依赖还要mysql,durid监控等。

2、Applications.yaml



spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/teamwork?useUnicode=true&characterEncoding;=UTF-8&useSSL;=false&serverTimezone;=Asia/Shanghai
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      stat-view-servlet: #配置监控页
        enabled: true
        login-password: admin
        login-username: 123456
        reset-enable: false
      web-stat-filter: #配置Web监控页面
        enabled: true
        url-pattern: /*
        exclusions: '*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*'
      aop-patterns: com.example.webadmin.* #Spring监控,监控webadmin包下所有配置
      filters: stat,wall
      filter:  #对防火墙和监控的详细配置
        stat:
          slow-sql-millis: 1000
          log-slow-sql: true
          enabled: true
        wall:
          enabled: true
          config:
            drop-table-allow: false
  redis:
    host: 127.0.0.1
    port: 6379
    password : Aiwin
mybatis:
  #config-location: classpath:mybatis/mybatis-config.xml  #全局配置文件位置
  mapper-locations: classpath:mybatis/mapper/*.xml  #sql映射文件位置
  configuration:
    map-underscore-to-camel-case: true

这里要使用redis,需要下载redis的数据库文件,启动,并且在 redis.windows.conf中设置自定义密码。

下载redis数据库链接:
链接:[https://pan.baidu.com/s/1vdleLjC4zyqoadRtxg_AyQ?pwd=4396
](https://pan.baidu.com/s/1vdleLjC4zyqoadRtxg_AyQ?pwd=4396
"https://pan.baidu.com/s/1vdleLjC4zyqoadRtxg_AyQ?pwd=4396 ")
提取码:4396

二、数据库文件

要实现以上功能,最简单的就要一个数据库的User表、然后这里还要实现Cookies自带一个Token实现免登录功能、所以还需要一个Token的数据库表。

数据库表的创建如下:



CREATE TABLE `token` (
  `username` varchar(50) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
  `tokenUUID` varchar(50) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;


CREATE TABLE `user` (
  `id` int(10) NOT NULL,
  `name` varchar(10) COLLATE utf8_unicode_ci NOT NULL,
  `phone` varchar(20) COLLATE utf8_unicode_ci NOT NULL,
  `username` varchar(20) COLLATE utf8_unicode_ci NOT NULL,
  `password` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
  `email` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
  `state` int(2) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

User类如下:



package com.example.teamwork.Bean;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private Integer id;
    private String name;
    private String phone;
    private String username;
    private String password;
    private String email;
    private Integer state;
}

Token类如下:



package com.example.teamwork.Bean;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Token {
    private String username;
    private String tokenUUID;
}

三、实现注册功能

注册功能主要需要利用到用户表,使用insert插入数据,这里操作数据库通过Mybatis,注册功能要需要收到验证码,通过要对信息进行验证,验证的地方有:两次密码是否一致,邮箱是否正确,邮箱是否能收到,还有通过Redis进行验证码的存储,主要通过redis的键存储邮箱,值存储为随机生成的六位验证码,然后通过设置reids的键expire为三分钟。

因为存入数据库的密码一般要使用加密的形式,这里使用base64后进行md5加密

MD5类:



package com.example.teamwork.config;


import org.springframework.util.DigestUtils;

import java.util.Base64;

import static com.mysql.cj.util.StringUtils.getBytes;

public class MD5 {
    /**
     * @param text明文
     * @param key密钥
     * @return 密文
     * 对数据库内的密码存储进行md5的加密
     */
    public static String md5(String password,String key) throws Exception {
            String base64encodedString = Base64.getEncoder().encodeToString((password + key).getBytes("utf-8"));
            // 加密后的字符串
            return DigestUtils.md5DigestAsHex(getBytes(base64encodedString));


        }

}


UserMapper如下:



package com.example.teamwork.mapper;

import com.example.teamwork.Bean.User;
import org.apache.ibatis.annotations.*;

import java.util.List;

@Mapper
public interface UserMapper {
    @Select("select *from user")
    List ShowStudent();
    @Insert("insert into user(`name`,`phone`,`username`,`password`,`email`,`state`) values(#{name},#{phone},#{username},#{password},#{email},#{state})")
    @Options(useGeneratedKeys = true,keyProperty = "id")
    void insert(User user);
    @Select("select *from user where phone=#{phone} and password=#{password}")
    User Login(String phone, String password);
    @Select("select *from user where email=#{email} and password=#{password}")
    User LoginByEmail(String email,String password);
    @Select("select *from user where email=#{email}")
    User retrieve(String email);
    @Update("update user SET password=#{password} where email=#{email}")
    Boolean SaveRetrieve(String password,String email);
    @Select("select *from user where phone=#{phone}")
    User SelectByPhone(String phone);
    @Select("select *from user where email=#{email}")
    User SelectByEmail(String email);
}

UserMapper.xml文件:





    
    select *from User
    
        
            and phone=#{phone}
        
        
            and phone=#{phone}
        
    
    

UserService层:



package com.example.teamwork.service;

import com.example.teamwork.Bean.User;

import java.util.List;

public interface UserService {
    void SaveUser(User user);
    List ShowStudent();

    User Login(String phone, String password);
    User retrieve(String email);
    User LoginByEmail(String email,String password);
    Boolean SaveRetrieve(String password,String email);
    User  SelectByPhone(String phone);
    User SelectByEmail(String email);
}

UserServiceImpl层:



package com.example.teamwork.service.imple;

import com.example.teamwork.Bean.User;
import com.example.teamwork.mapper.UserMapper;
import com.example.teamwork.service.UserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service
public class UserServiceImp implements UserService {
    @Resource
    UserMapper userMapper;

    @Override
    public void SaveUser(User user) {
        userMapper.insert(user);
    }

    @Override
    public List ShowStudent() {
        return userMapper.ShowStudent();
    }

    @Override
    public User Login(String phone, String password) {
        return userMapper.Login(phone,password);
    }

    @Override
    public User retrieve(String email) {
        return userMapper.retrieve(email);
    }

    @Override
    public User LoginByEmail(String email, String password) {
        return userMapper.LoginByEmail(email,password);
    }

    @Override
    public Boolean SaveRetrieve(String password,String email) {
        userMapper.SaveRetrieve(password,email);
        return true;
    }

    @Override
    public User SelectByPhone(String phone) {
        return userMapper.SelectByPhone(phone);
    }

    @Override
    public User SelectByEmail(String email) {
        return userMapper.SelectByEmail(email);
    }


}

            return "信息填写不能为空或填写信息过短";
        }
        List list=sendMailUtil.usermapper.ShowStudent();
        for(User user:list){
            if(phone.equals(user.getPhone()) || name.equals(user.getName())|| Objects.equals(email, user.getEmail())){
                return "您已注册";
            }
        }
        return "填写正确";
    }
    /**
     * 检查密码和重复密码是否一致
     * @param password
     * @param RepeatPassword
     * @return
     */
    public boolean CheckPassword(String password,String RepeatPassword){
        return Objects.equals(password, RepeatPassword);
    }
    /**

     */

    public  boolean isEmail(String email) {
        if (email == null || email.length() < 1 || email.length() > 256) {
            return false;
        }
        Pattern pattern = Pattern.compile("^\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*$");
        return pattern.matcher(email).matches();
    }

四、找回密码功能

找回密码功能相对比较简单,只需要填写邮箱,然后判断邮箱是否已注册,注册则发送验证码后,进行密码的重置即可。

RetrievePassword.java类如下:



package com.example.teamwork.controller;

import com.example.teamwork.Bean.User;
import com.example.teamwork.config.MD5;
import com.example.teamwork.config.SendMailUtil;
import com.example.teamwork.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;
import java.util.Map;
import java.util.Objects;
import java.util.concurrent.TimeUnit;

@Controller
public class RetrievePassword {
    @Autowired
    RedisTemplate redisTemplate;
    @Resource
    UserService userService;

    /**
     * 通过前端ajax发送email进行验证码的发送,并生成code存入Redis,有效未3分钟,在此期间判断邮箱格式和是否被注册
     * @param json
     * @return
     */
    @RequestMapping("/retrieve")
    @ResponseBody
    public String retrieve_sendCode(@RequestParam Map json) {
        String message;
        try {
            String email = (String) json.get("email");
            SendMailUtil sendMailUtil = new SendMailUtil();
            if (!sendMailUtil.isEmail(email)) {
                message = "邮箱格式不正确";
            } else {
                User user = userService.retrieve(email);
                if (user == null) {
                    message = "此邮箱未注册";
                } else {
                    ValueOperations operations = redisTemplate.opsForValue();
                    if(operations.get(email)!=null){
                        message= "验证码已发送,请三分钟后重试";
                    }
                    else {
                        StringBuilder code = sendMailUtil.CreateCode();
                        operations.set(email, String.valueOf(code));
                        redisTemplate.expire(email, 3, TimeUnit.MINUTES);
                        message=sendMailUtil.sendQQEmail("lauaiwin@foxmail.com", "rbrxjhnoxspgdiej", email, String.valueOf(code), user.getName());
                    }
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
            message = "出现未知错误";
        }
        return message;
    }

    /**
     * 通过ajax发送数据,检查两次密码是否一致,邮箱是否和获取验证码的一致,验证码是否和redis中的一致,全通过则修改成功
     * @param json
     * @return
     * @throws Exception
     */
    @PostMapping("/SaveRetrieve")
    @ResponseBody
    public String SaveRetrieve(@RequestParam Map json) throws Exception {
        String password= (String) json.get("password");
        String repassword= (String) json.get("repassword");
        String email= (String) json.get("email");
        String code= (String) json.get("code");
        ValueOperations operations = redisTemplate.opsForValue();
        String get_code= operations.get(email);
        SendMailUtil sendMailUtil=new SendMailUtil();
        String message="";
        int SureInformation=1;
        if(!sendMailUtil.CheckPassword(password,repassword)||password.length()<3) {
            SureInformation = 0;
            message= "两次密码不匹配或者密码过短";
        }
        if(get_code==null|| !Objects.equals(code, get_code)){
            SureInformation=0;
            message = "邮箱或验证码不正确";
        }
        if(SureInformation==1) {
            String sure_password = MD5.md5(password, "Aiwin");
            if (userService.SaveRetrieve(sure_password,email)) {
                return "修改成功";
            }


        }

        return message;
    }
}

index.html页面如下:

这里主要找回密码功能嵌入了index的登录页面,点击找回密码即会响应弹出找回密码的框

五、登录功能

这里的登录功能主要使用双重登录,通过手机号和邮箱登录都可行,思路就是先对输入的账号和密码进行一次手机号的取数据库的操作,假如取不出,那就再使用邮箱和密码进行一次取用户的操作,假如还取不出,那就登录失败,否则有一次取出了,则通过登录,通过登录后生成一个TokenID,然后将通过用户的用户名和TokenID存入数据库,下次再进入/页面的时候,浏览器会将存储的Cookie传回来,遍历Cookie,取出Cookie中的TokenID,假如能在数据库中找到TokenID,那就将TokenID取出的数据中的username取出用户的数据,然后嵌入Session中。登录后,设置一个退出按钮,按退出则删除数据库中的TokenID的字段即可,下次就需要重新登录了。

TokenService:



package com.example.teamwork.service;

import com.example.teamwork.Bean.Token;

public interface TokenService {
    void addToken(Token token);
    String searchToken(String tokenUUID);
    boolean deleteToken(String username);
}

TokenServiceImpl:



package com.example.teamwork.service.imple;

import com.example.teamwork.Bean.Token;
import com.example.teamwork.mapper.TokenMapper;
import com.example.teamwork.service.TokenService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service
public class TokenServiceImpl implements TokenService {
    @Resource
    TokenMapper tokenMapper;

    @Override
    public void addToken(Token token) {
        tokenMapper.insert(token);
    }

    @Override
    public String searchToken(String tokenUUID) {
       return tokenMapper.selectByToken(tokenUUID);
    }

    @Override
    public boolean deleteToken(String username) {
        return tokenMapper.deleteToken(username);
    }
}

此处RSA类主要是实现index页面的记住我功能,公钥在前端,通过前端对localstorge的账号密码进行RSA加密后,要进行一次base64加密,便于传入+号和\号,传入后端后,通过remember_to_login是否为1判断是否是记住我进行登录的,是则先利用后端的私钥进行解密后再查找数据库,判断用户是否登录成功。
