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=#这里配置你的邮箱spring.mail.username=XXX@spring.mail.password=开启smtp时候的授权码spring.mail.default-encoding=utf-8spring.mail.port=465spring.mail.protocol=smtpsspring.mail.properties.mail.smtp.socketFactory.class=.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.mon.BusiException;import com.qiyuan.qyframe.base.util.RedisUtil;import lombok.extern.slf4j.Slf4j;import mons.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@Servicepublic class EmailService {@Value("${spring.mail.host}")private String host;@Value("${spring.mail.username}")private String username;@Value("${spring.mail.password}")private String password;@Autowiredprivate RedisUtil redisUtil;@Autowiredprivate 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
