Jmail发送邮件工具类分享

 好久没更新博客了，实在是拖延症严重啊，好可怕，先更新个工具类吧，之前写的发送邮件的小工具，话不多说上代码

import lombok.extern.slf4j.Slf4j;

import java.util.Properties;

import javax.mail.*;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


@Slf4j
public class SendMailUtil {

  
  public static boolean doSendEmail(String smtpHost, final String fromUser,
  final String fromUserPassword, String userName, String emailPort, String toUser, String subject,
  String messageText) throws Exception {
    boolean flag = false;
    try {
      Properties props = new Properties();
      props.put("mail.smtp.host", smtpHost);
      props.put("mail.smtp.port", emailPort);
      props.put("mail.smtp.auth", "true");
      Session session = Session.getDefaultInstance(props, new Authenticator(){
 protected PasswordAuthentication getPasswordAuthentication() {
   return new PasswordAuthentication(fromUser, fromUserPassword);
 }});
      MimeMessage message = new MimeMessage(session);
      // 发件人
      InternetAddress from = new InternetAddress(fromUser);
      message.setFrom(from);
      // 收件人
      InternetAddress to = new InternetAddress(toUser);
      message.setRecipient(Message.RecipientType.TO, to);
      // 邮件标题
      message.setSubject(subject);
      // 邮件内容,也可以使纯文本"text/plain"
      message.setContent(messageText, "text/html;charset=GBK");
      message.saveChanges();
      Transport transport = session.getTransport("smtp");
      // smtp验证，就是你用来发邮件的邮箱用户名密码
      transport.connect(smtpHost, userName, fromUserPassword);
      // 发送
      transport.sendMessage(message, message.getAllRecipients());
      transport.close();
      flag = true;
    } catch (AddressException e) {
      log.error("地址异常:{}", e);
      throw e;
    } catch (MessagingException e) {
      log.error("消息异常:{}", e);
      throw e;
    } catch (Exception e) {
      log.error("系统异常:{}", e);
      throw e;
    }

    return flag;
  }
}
