Java集成EmailService

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.util.Date;

@Component
@Slf4j
public class EmailUtils {
    @Autowired
    JavaMailSender javaMailSender;

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

    public void sendHtml(String title, String html, String to) {
        MimeMessage mailMessage = javaMailSender.createMimeMessage();
        //需要借助Helper类
        MimeMessageHelper helper = new MimeMessageHelper(mailMessage);
        try {
            helper.setFrom(username);  // 必填
            helper.setTo(to);   // 必填
//            helper.setBcc("密送人");   // 选填
            helper.setSubject(title);  // 必填
            helper.setSentDate(new Date());//发送时间
            helper.setText(html, true);   // 必填  第一个参数要发送的内容,第二个参数是不是Html格式。
            javaMailSender.send(mailMessage);
        } catch (MessagingException e) {
            log.error("发送邮件失败", e);
        }
    }

}

在controller里定义接口:

@ApiOperation(value = "邮箱验证接口")
@GetMapping("/email")
public Result sendEmail(@RequestParam String email, @RequestParam String type) {
    userService.sendEmail(email, type);
    return Result.success();
}

在业务实现层UserServiceImpl写业务逻辑

void sendEmail(String email, String type);

private static final Map<String, Long> CODE_MAP = new ConcurrentHashMap<String, Long>();

@Resource
EmailUtils emailUtils;
@Override
public void sendEmail(String email, String type) {
  String  code = RandomUtil.randomNumbers(6);
  log.info("本次验证码的code是:{}", code);
  String context = "<b>尊敬的用户:</b><br><br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;您好," +
    "Partner交友网提醒您本次的验证码是:<b>{}</b>," +
    "有效期5分钟。<br><br><br><b>Partner交友网</b>";
  String html = StrUtil.format(context, code);
  if ("REGISTER".equals(type)) {
    // 多线程异步请求
    ThreadUtil.execAsync(() -> {
      emailUtils.sendHtml("【partner交友网】邮箱注册验证",html, email);
    });
    CODE_MAP.put(code, System.currentTimeMillis());
  }
}
输入邮箱,点击发送:

在后端我们可以看到验证码为:

登录邮箱:查看邮件即可
