高子歌 2023-12-07 阅读 45

1、以QQ邮箱为例,点开设置开启POP3/SMTP服务

SpringBoot整合邮箱发送验证码_spring

2、创建一个springboot项目

1)引入maven依赖

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

2)配置yml文件

spring:
  mail:
    # 配置 SMTP 服务器地址
    host: smtp.qq.com
    # 发送者邮箱
    username: 1234567@qq.com
    # 配置密码,注意不是真正的密码,而是刚刚申请到的授权码
    password: etorqsqmpsrtbada
    # 端口号465或587
    port: 587
    # 默认的邮件编码为UTF-8
    default-encoding: UTF-8
    # 配置SSL 加密工厂
    properties:
      mail:
        smtp:
          socketFactoryClass: javax.net.ssl.SSLSocketFactory
        #表示开启 DEBUG 模式,这样,邮件发送过程的日志会在控制台打印出来,方便排查错误
        debug: true

3)创建controller

package com.atguigu.msmservice.controller;
 
import com.atguigu.commonutils.R;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.web.bind.annotation.*;
 
import javax.annotation.Resource;
 
import java.util.Random;
import java.util.concurrent.TimeUnit;
 
@RestController
@RequestMapping("/messervice/email")
@CrossOrigin
public class EmailController {
    @Autowired
    private RedisTemplate<String,String> redisTemplate;
    @Resource
    private JavaMailSender javaMailSender;
 
    //读取yml文件中username的值并赋值给form
    @Value("${spring.mail.username}")
    private String from;
 
    @GetMapping("/sendEmail/{emailReceiver}")
    public R sendSimpleMail(@PathVariable String emailReceiver) {
        // 构建一个邮件对象
        SimpleMailMessage message = new SimpleMailMessage();
        // 设置邮件发送者
        message.setFrom(from);
        // 设置邮件接收者
        message.setTo(emailReceiver);
        // 设置邮件的主题
        message.setSubject("登录验证码");
        // 设置邮件的正文
        Random random = new Random();
        StringBuilder code = new StringBuilder();
        for (int i = 0; i < 6; i++) {
            int r = random.nextInt(10);
            code.append(r);
        }
        String text = "您的验证码为:" + code + ",请勿泄露给他人。";
        message.setText(text);
 
        // 发送邮件
        try {
            javaMailSender.send(message);
            //将验证码保存到redis缓存中,设置有效时间为5分钟
            redisTemplate.opsForValue().set(emailReceiver, String.valueOf(code),5, TimeUnit.MINUTES);
            return R.ok();
        } catch (MailException e) {
            e.printStackTrace();
        }
        return R.error().message("发送失败");
    }
}
