基於SpringBoot實現郵箱找回密碼


基於郵箱發送驗證碼的方式

實現思路

  1. 用戶點擊忘記密碼
  2. 用戶輸入用戶名以及郵箱,點擊獲取驗證碼
  3. 后端校驗用戶名以及郵箱,正確后生成驗證碼
  4. 生成的驗證碼作為value,前綴加用戶名為key,放入redis中並設置過期時間
  5. 用戶輸入驗證碼以及新的密碼點擊保存
  6. 后端通過前綴+用戶名獲取驗證碼,校驗驗證碼的正確性
  7. 密碼修改成功

前端UI頁面

圖為ProcessOn所畫,可作為借鑒。也可設計為先驗證用戶名然后再進入改密碼頁面。

發件郵箱要求

作者使用的是163郵箱(其他郵箱也基本一致),需要設置POP3/SMTP/IMAP

開啟

  • IMAP/SMTP服務
  • POP3/SMTP服務
    開啟會讓設置授權碼,授權碼要記牢!后面需要寫在配置里

再往下翻有163 SMTP服務器地址 等下需要配置在application.yml中

各家郵箱大同小異,企業郵箱的話應該是可以直接用的,不用開啟。

代碼實現

1. 依賴

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2. application.yml配置

# 配置郵箱服務器,賬號密碼等
spring:
  mail:
    host: smtp.163.com
    username: xxxxxx@163.com
    password: ERBDGXLVJAQMWMDI(授權碼)

3. 獲取驗證碼controller

import com.clisoft.srmsbackend.common.response.ServerResponse;
import com.clisoft.srmsbackend.service.IMailService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 郵箱業務 前端控制器
 * @author zzw
 * @date 2022-01-14
 */
@Api(tags = "郵箱業務管理")
@RestController
@RequestMapping("/mail")
public class MailController {

    @Autowired
    private IMailService mailService;

    /**
     * 獲取重置密碼的驗證碼
     */
    @ApiOperation(value = "獲取重置密碼的驗證碼", notes = "獲取重置密碼的驗證碼", httpMethod = "GET")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "staffNumber", value = "用戶編號(賬號)", required = true, paramType = "form"),
            @ApiImplicitParam(name = "mailAddress", value = "郵箱地址", required = true, paramType = "form"),
    })
    @GetMapping("/getCode")
    public ServerResponse getCode(String staffNumber,String mailAddress){
        return mailService.getCode(staffNumber,mailAddress);
    }
}

4. ServiceImpl層

import java.util.concurrent.TimeUnit;

/**

@Service
public class MailServiceImpl implements IMailService {

    @Autowired
    private PersStaffMapper persStaffMapper;

    @Autowired
    private MailCodeConfig mailCodeConfig;

    @Autowired
    private RedisCache redisCache;

    @Autowired
    private JavaMailSender mailSender;

    @Value("${spring.mail.username}")
    private String mailUserName;

    /**
     * 獲取重置密碼的驗證碼
     *
     * @param staffNumber 用戶賬號
     * @param mailAddress 用戶郵箱
     * @return
     */
    @Override
    public ServerResponse getCode(String staffNumber, String mailAddress) {
        // 非空校驗
        if (null == staffNumber || "".equals(staffNumber)) return ServerResponse.createByErrorMessage("賬號不能為空!");
        if (null == mailAddress || "".equals(mailAddress)) return ServerResponse.createByErrorMessage("郵箱不能為空!");

        // 賬號存在校驗
        PersStaff persStaff = persStaffMapper.selectPersStaffByStaffNumber(staffNumber);
        if (null == persStaff) return ServerResponse.createBySuccessMessage("賬號不存在!");
        if (!persStaff.getEmail().equals(mailAddress)) return ServerResponse.createByErrorMessage("輸入郵箱和預留郵箱不一致!");

        String verifyCode = redisCache.getCacheObject(Constants.MAIL_CODE_KEY + staffNumber);
        if (verifyCode == null) {
            verifyCode = String.valueOf(new Random().nextInt(899999) + 100000);//生成短信驗證碼
        }
        Integer overtime = mailCodeConfig.getOvertime(); // 過期時間
        // 驗證碼存入redis並設置過期時間
        redisCache.setCacheObject(Constants.MAIL_CODE_KEY + staffNumber, verifyCode, overtime, TimeUnit.MINUTES);

        // 編寫郵箱內容
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("<html><head><title></title></head><body>");
        stringBuilder.append("您好<br/>");
        stringBuilder.append("您的驗證碼是:").append(verifyCode).append("<br/>");
        stringBuilder.append("您可以復制此驗證碼並返回至科研管理系統找回密碼頁面,以驗證您的郵箱。<br/>");
        stringBuilder.append("此驗證碼只能使用一次,在");
        stringBuilder.append(overtime.toString());
        stringBuilder.append("分鍾內有效。驗證成功則自動失效。<br/>");
        stringBuilder.append("如果您沒有進行上述操作,請忽略此郵件。");
        MimeMessage mimeMessage = mailSender.createMimeMessage();

        // 發件配置並發送郵件
        try {
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
            //這里只是設置username 並沒有設置host和password,因為host和password在springboot啟動創建JavaMailSender實例的時候已經讀取了
            mimeMessageHelper.setFrom(mailUserName);
            // 用戶的郵箱地址
            mimeMessageHelper.setTo(mailAddress);
            // 郵件的標題
            mimeMessage.setSubject("郵箱驗證-科研管理系統");
            // 上面所拼接的郵件內容
            mimeMessageHelper.setText(stringBuilder.toString(), true);
            mailSender.send(mimeMessage);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
        return ServerResponse.createBySuccessMessage("獲取驗證碼成功,請查看移步您的郵箱" + mailAddress + "查看驗證碼!");
    }
}

5. 修改密碼controller

/**
     * 驗證碼重置密碼
     */
    @ApiOperation(value = "驗證碼重置密碼", notes = "驗證碼重置密碼", httpMethod = "POST")
    @PostMapping("/codeUpdatePwd")
    public ServerResponse codeUpdatePwd(@RequestBody CodeUpdatePwdVo codeUpdatePwdVo){
        return persStaffService.codeUpdatePwd(codeUpdatePwdVo);
    }

6. 修改密碼ServiceImpl

 /**
     * 驗證碼重置密碼
     *
     * @param codeUpdatePwdVo
     * @return
     */
    @Override
    public ServerResponse codeUpdatePwd(CodeUpdatePwdVo codeUpdatePwdVo) {
        String staffNumber = codeUpdatePwdVo.getStaffNumber();
        String code = codeUpdatePwdVo.getCode();
        String loginPassword = codeUpdatePwdVo.getLoginPassword();
        // 非空校驗
        if (null == staffNumber || "".equals(staffNumber)) return ServerResponse.createByErrorMessage("賬號不能為空!");
        if (null == code || "".equals(code)) return ServerResponse.createByErrorMessage("驗證碼不能為空!");
        if (null == loginPassword || "".equals(loginPassword)) return ServerResponse.createByErrorMessage("密碼不能為空!");

        // 賬號存在校驗
        PersStaff persStaff = persStaffMapper.selectPersStaffByStaffNumber(staffNumber);
        if (null == persStaff) return ServerResponse.createBySuccessMessage("賬號不存在!");

        // 驗證碼過期校驗
        String cacheCode = redisCache.getCacheObject(Constants.MAIL_CODE_KEY + staffNumber); // 獲取緩存中該賬號的驗證碼
        if (cacheCode == null) {
            return ServerResponse.createByErrorMessage("驗證碼已過期,請重新獲取!");
        }

        // 驗證碼正確性校驗
        if (!cacheCode.equals(code)) {
            return ServerResponse.createByErrorMessage("驗證碼錯誤!");
        }

        // 修改密碼
        int result = 0;
        try {
            result = persStaffMapper.updatePwdByStaffNumber(staffNumber, PasswordStorageUtil.createHash(codeUpdatePwdVo.getLoginPassword()));
        } catch (PasswordStorageUtil.CannotPerformOperationException e) {
            return ServerResponse.createByErrorMessage("密碼加密時發生錯誤");
        }
        if (result > 0) {
            // 將驗證碼過期
            redisCache.expire(Constants.MAIL_CODE_KEY + staffNumber, 0);
            return ServerResponse.createBySuccessMessage("密碼充值成功!請牢記您的密碼!");
        }

        return ServerResponse.createByErrorMessage("未知錯誤,密碼修改失敗,請重試!");
    }
