创建一个Controller类
@RestController
@RequestMapping("/email")
public class EmailController {
@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;
@RequestMapping("sendEmail")
public String sendSimpleMail(@RequestParam(value = "emailReceiver") 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);
return "发送成功";
} catch (MailException e) {
e.printStackTrace();
}
return "发送失败";
}
}
