如何使用javamail api更快地发送邮件

Question

在我的场景中，我使用jasper报告生成了一个pdf。我已经发送邮件给我的上司并附上pdf但邮件发送过程需要一分多钟。那么我用一秒钟发送邮件的方法，你可以使用javamail api帮助编写任何编码格式。在这里，我已经为您提供了输入邮件发送编码结构。感谢

public boolean sendMailForVacation(String subject, String bodyContent,String emailAddress,byte[] pdfFile,String pdfFileName,String company){
          boolean isMailsent=false;
          final String SMTP_HOST= getText("email.smtp.host");
          final String SOCKET_FACTORY_PORT= getText("email.socket.factory.port");
             final String SMTP=getText("email.smtp.port"); 
          final String MAIL_USER_EMAIL_ADDRESS=getText("email.username");
          final String MAIL_USER_PASSWORD= getText("email.password");
          final String EMAIL_FROMNAME= company;//getText("email.fromname");
          try{
           Properties props = new Properties();
           props.put("mail.smtp.host", SMTP_HOST);
           props.put("mail.smtp.socketFactory.port",SOCKET_FACTORY_PORT);
           props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
           props.put("mail.smtp.auth", "true");
           props.put("mail.smtp.port", SMTP);
           Authenticator auth = new SMTPAuthenticator(MAIL_USER_EMAIL_ADDRESS, MAIL_USER_PASSWORD);
              Session session = Session.getInstance(props, auth);
           Message message = new MimeMessage(session);
           InternetAddress from = new InternetAddress(MAIL_USER_EMAIL_ADDRESS,EMAIL_FROMNAME);  
           message.setFrom(from);
           message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(emailAddress));
           message.setSubject(subject);
           MimeMultipart multipart = new MimeMultipart("related");
                  BodyPart messageBodyPart = new MimeBodyPart();
                  messageBodyPart.setContent(bodyContent, "text/html");
                  multipart.addBodyPart(messageBodyPart);
                      messageBodyPart = new MimeBodyPart();
                      ByteArrayDataSource baDS=new ByteArrayDataSource(pdfFile,"application/pdf");//application/vnd.ms-excel  
                      messageBodyPart.setDataHandler(new DataHandler(baDS));  
                      messageBodyPart.setFileName(pdfFileName); 
                      multipart.addBodyPart(messageBodyPart);
                      message.setContent(multipart);
                      Transport.send(message);
                      isMailsent=true;
          }catch(Exception e){
           LOGGER.error(e);
          }
          return isMailsent;
         }
