1.开启邮箱服的POP3/IMAP/SMTP 服务
1.打开网页QQ邮箱，找到设置---->账户—>服务，开启服务。
注意：要用QQ登录的邮箱，微信登录邮箱会出问题
2.导入工具包

dependency>
3.代码编写
在application.yml配置信息
Email:
host: smtp.qq.com
username: 填你的邮箱
password: 填授权码
port: 587
编写一个service类

新建controller类，进行测试
@RestController
public class SendCodeController {
@Autowired
private EmailService emailService;
@GetMapping("/sendCode")
public String sendCode(String email) throws MessagingException {
System.out.println("11111");
emailService.sendCode(email);
return "发送成功";
}
}
发送请求，进行测试
功能成功实现
