 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;

  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;
  }
}
