springboot整合邮箱验证_springboot.yml中配置邮箱

前提条件

我用的是163邮箱，优先需要授权码，如何开启授权码请参考链接

1.先上pom依赖

<!--    邮箱依赖-->
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>

2.在yml设置

spring:
  mail:
    host: smtp.163.com
    default-encoding: utf-8
    password: 授权码
    username: 自己的163邮箱
    properties:
      mail:
        smtp:
          ssl: enable=true

 3.新建一个MailController.java文件

@RestController
public class MailController {
    @Value("${spring.mail.username}")
    private  String from;
 
    @Autowired
    private JavaMailSender mailSender;
 
 
    @RequestMapping("/sendmail")
    public boolean sendMimeMail(String email, HttpSession httpSession) {
        try {
            //声明一个邮件发送请求
            SimpleMailMessage mailMessage=new SimpleMailMessage();
            //调用6位随机数随机数
            String code = randomCode();
            //将随机数放入Session中
            httpSession.setAttribute("email","要发送到的邮箱");
            httpSession.setAttribute("code",code);
            //邮件验证消息
            mailMessage.setSubject("邮件验证消息");
            //收到的验证码
            mailMessage.setText("收到的验证码："+code);
            //发给谁
            mailMessage.setTo("要发送到的邮箱");
            //从哪发
            mailMessage.setFrom(from);
            //发送
            mailSender.send(mailMessage);
            return  true;
        }catch (Exception e){
            e.printStackTrace();
            return  false;
        }
    }
 
    //6位验证码
    public String randomCode(){
        StringBuilder stringBuilder = new StringBuilder();
        Random random=new Random();
        for (int i=0;i<6;i++){
            //从0-9中随机数
            stringBuilder.append(random.nextInt(10));
        }
        return stringBuilder.toString();
    }
 
}

4.调用接口

5.我是发送到QQ邮箱

 即可大功告成!
