【邮箱验证码】springboot 使用邮箱服务发送验证码 ，在阿里云服务器端口的配置

1、我们需要登录邮箱开通邮箱授权码

2、然后需要pom需要引入spring-boot-starter-mail

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>2.6.4</version>
    </dependency>

需要在配置文件 application.properties里面添加

<!-- 邮箱验证 -->
#163邮箱
spring.mail.host=smtp.163.com
#这里配置你的邮箱
spring.mail.username=XXX@163.com
spring.mail.password=开启smtp时候的授权码
spring.mail.default-encoding=utf-8
spring.mail.port=465
spring.mail.protocol=smtps
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

如果这里指定465端口，该端口和项目服务端口不冲突。邮件发送协议必须是smtps 不指定发送邮件时会报错，所以必须指定protocol配置为smtps

逻辑代码

上边pom的spring-boot-starter-mail引入后你能使用

JavaMailSender 是mail包提供的

package com.qiyuan.qyframe.base.service;

import com.qiyuan.qyframe.base.common.BusiException;
import com.qiyuan.qyframe.base.util.RedisUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import java.util.Random;

@Slf4j
@Service
public class EmailService {
    
    

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

    @Autowired
    private RedisUtil redisUtil;
    @Autowired
    private JavaMailSender sender;

   
    public void sendEmailCode(String email) {
    
    
        if (StringUtils.isBlank(email)) {
    
    
            throw new BusiException("请输入正确的邮箱账号");
        }
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(username);
        message.setTo(email);
        message.setSubject("验证码");
        String verificationCode = String.valueOf(new Random().nextInt(899999) + 100000);
        //System.out.println(verificationCode);
        message.setText("尊敬的用户你好，你所收到的验证码: " + verificationCode);

        sender.send(message);
        //将验证码放入Redis中,并定时五分钟，五分钟后删除
        redisUtil.set(email, verificationCode, 5 * 60);

    }
}

然后你就可以在你的业务代码中调上边封装的EmailService了

	@AnonymousAccess
    @RequestMapping(value = "/emailCode", method = RequestMethod.POST)
    public ResponseData emailCode(String email) {
    
    
        String errMsg = "";
        try {
    
    
            emailService.sendEmailCode(email);

        } catch (BusiException e) {
    
    
            errMsg = e.getMessage();
            log.error("PhoneCodeController-emailCode occur BusiException", e);
            return ResponseDataUtil.buildSuccess(ResultEnums.ERROR.getCode(), errMsg);
        } catch (Exception e) {
    
    
            //异常信息
            errMsg = "系统错误";
            log.error("PhoneCodeController-emailCode occur Exception", e);
            return ResponseDataUtil.buildSuccess(ResultEnums.ERROR.getCode(), errMsg);
        }
        return ResponseDataUtil.buildSuccess(ResultEnums.SUCCESS.getCode(), "操作成功");

    }

流程大概就这些啦，应该没啥问题了，搞定
