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) {

}
}
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> 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());
}
}
