SpringBoot+Redis+QQ邮箱实现验证码发送及缓存

目录

1.开启服务：POP3/SMTP服务

 获取授权码​

2.添加maven依赖

3.在application.properties中进行配置

4.Service层

MsmService

实现类：MsmServiceImpl

5.Controller层

MsmController

6.测试结果

 成功收到邮件

redis中存储成功

注：如果有小伙伴不需要使用redis或者暂时用不到redis，下面我对代码需要修改的地方已经进行了说明，进行改正即可。

     org.springframework.boot
     spring-boot-starter-mail

username为发件者邮箱

password为刚刚获得的授权码

host为 SMTP 服务器地址，可以不用更改

#邮箱发件人及授权码信息
spring.mail.default-encoding=UTF-8
spring.mail.username=18*******221@qq.com
spring.mail.password=fxc**********ed
spring.mail.host=smtp.qq.com


#下面是redis的配置，如果用不到可以不用配置，这里只是用作缓存
spring.redis.host=192.1**.1*.251
spring.redis.port=6379
spring.redis.database= 0
#redis配置密码则添加，没有则无需配置
spring.redis.password=aA6dD4
spring.redis.timeout=1800000

        String text = "您的验证码为：" + code + ",5分钟内有效,请勿泄露给他人。";
        message.setText(text);
        // 发送邮件
        try {
            javaMailSender.send(message);

@RestController
@RequestMapping("edumsm")
@CrossOrigin
public class MsmController {
    @Autowired
    private MsmService msmService;
    
    //*不用redis可以删去该自动装配
    @Autowired
    private RedisTemplate redisTemplate;

    @RequestMapping("sendEmail/{emailReceiver}")
    public Result sendSimpleMail(@PathVariable("emailReceiver") String emailReceiver) {
        //从Redis中获取code
        String code = redisTemplate.opsForValue().get(emailReceiver);
        if (!StringUtils.isEmpty(code)){
            return Result.ok();
        }
        code= RandomUtil.getSixBitRandom();
        // 构建一个邮件对象
        Boolean mail = msmService.sendMail(code, emailReceiver);
        if (mail){
            //设置有效时间,这里是5分钟，*不用redis可以删去该行
            redisTemplate.opsForValue().set(emailReceiver,code,5, TimeUnit.MINUTES);
            return Result.ok();
        }
        return Result.error().message("邮件发送失败");
    }

}

以上的Result为结果集

        return r;
    }

    private Result() {
