前言
提示：这里可以添加本文要记录的大概内容：
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.Driverurl: jdbc:mysql://localhost:3306/teamwork?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghaiusername: rootpassword: roottype: com.alibaba.druid.pool.DruidDataSourcedruid:stat-view-servlet: #配置监控页enabled: truelogin-password: adminlogin-username: 123456reset-enable: falseweb-stat-filter: #配置Web监控页面enabled: trueurl-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,wallfilter: #对防火墙和监控的详细配置stat:slow-sql-millis: 1000log-slow-sql: trueenabled: truewall:enabled: trueconfig:drop-table-allow: falseredis:host: 127.0.0.1port: 6379password : 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。

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<User> 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:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">

</mapper>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<User> 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);
}

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 {@AutowiredRedisTemplate redisTemplate;@ResourceUserService 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")@ResponseBodypublic String retrieve_sendCode(@RequestParam Map<String, Object> 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<String, String> 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")@ResponseBodypublic String SaveRetrieve(@RequestParam Map<String, Object> 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<String, String> 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;}
}

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);
}

}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。

function base64encode(str) {var base64encodechars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";var out, i, len;var c1, c2, c3;len = str.length;i = 0;out = "";while (i < len) {c1 = str.charCodeAt(i++) & 0xff;if (i === len) {out += base64encodechars.charAt(c1 >> 2);out += base64encodechars.charAt((c1 & 0x3) << 4);out += "==";break;}c2 = str.charCodeAt(i++);if (i === len) {out += base64encodechars.charAt(c1 >> 2);out += base64encodechars.charAt(((c1 & 0x3) << 4) | ((c2 & 0xf0) >> 4));out += base64encodechars.charAt((c2 & 0xf) << 2);out += "=";break;}c3 = str.charCodeAt(i++);out += base64encodechars.charAt(c1 >> 2);out += base64encodechars.charAt(((c1 & 0x3) << 4) | ((c2 & 0xf0) >> 4));out += base64encodechars.charAt(((c2 & 0xf) << 2) | ((c3 & 0xc0) >> 6));out += base64encodechars.charAt(c3 & 0x3f);}return out;
}
总结
总的来说，思路还是比较简单，主要通过mysql数据库信息的增删查，然后通过redis存储验证码就能实现，但是做的肯定比较查，交个作业还是可以的。
