Google App Engine (Java)에서 인라인 이미지가 포함 된 이메일을 보내려고합니다. 내 코드는 다음과 같습니다.Google App Engine (Java)에서 인라인 이미지가있는 이메일 보내기

public void send(RecepientInfo[] toAddress, String subject, Attachment[] attachements) throws MessagingException, IOException { 
    try { 
     MimeBodyPart textPart = new MimeBodyPart(); 
     MimeBodyPart htmlPart = new MimeBodyPart(); 
     Multipart mp = new MimeMultipart(); 

     msg = new MimeMessage(session); 
     msg.setFrom(utils.getSenderInfo()); 
     for (RecepientInfo address : toAddress) { 
      msg.addRecipient(address.getType(), address.getAddress()); 
     } 
     msg.setSubject(subject); 
     Template textTpl = cfg.getTemplate("text.ftl"); 
     Template htmlTpl = cfg.getTemplate("html.ftl"); 
     StringWriter swText = new StringWriter(); 
     StringWriter swHtml = new StringWriter(); 
     textTpl.process(parameters, swText); 
     htmlTpl.process(parameters, swHtml); 
     String html = swHtml.toString(); 
     String text = swText.toString(); 
     textPart.setText(text, "text/plain"); 
     htmlPart.setContent(html, "text/html"); 
     mp.addBodyPart(textPart); 
     mp.addBodyPart(htmlPart); 

     if (attachements != null) { 
      for (Attachment item : attachements) { 
       mp.addBodyPart(getImageMultiPart(item.base64Content.getBytes(), item.mimeType, item.contentId, item.fileName, MimeBodyPart.INLINE)); 
      } 
     } 

     msg.setContent(mp); 
     Transport.send(msg); 
     if (Constants.IS_DEV_MODE) { 
      System.out.println(text); 
     } 
    } catch (TemplateException te) { 
     throw new IOException(te); 
    } 
} 

private BodyPart getImageMultiPart(byte[] base64EncodedImageContentByteArray, String mimeType, String contentId, String fileName, String bodyPart) throws MessagingException { 
    InternetHeaders headers = new InternetHeaders(); 
    headers.addHeader("Content-Type", mimeType); 
    headers.addHeader("Content-Transfer-Encoding", "base64"); 
    MimeBodyPart imagePart = new MimeBodyPart(headers, base64EncodedImageContentByteArray); 
    imagePart.setDisposition(bodyPart); 
    if (contentId != null) { 
     imagePart.setContentID("<" + contentId + ">"); 
    } 
    if (fileName != null) { 
     imagePart.setFileName(fileName); 
    } 
    return imagePart; 
} 

하지만이 메일을 보내하려고 할 때,이 같은 약간의 오차가 점점 오전 :

솔루션은 바보입니다.

내가 setFileName으로 설정하면 적절한 확장자를 가진 문자열을 전달해야했습니다.

그래서 대신

imagePart.setFileName(fileName); 

내가 가지고 사용하는

imagePart.setFileName(fileName + "." + mimeType.substring(mimeType.indexOf("/") + 1));
