發送帶有zip文件附件的電子郵件時出現ParseException？

Question

發送帶有壓縮文件附件的電子郵件時出現異常，有什么建議嗎？

引起原因：javax.mail.internet.ParseException：預期為'/'，javax.mail.internet.MimeBodyPart.updateHeaders(MimeBodyPart.java:1322）處的javax.mail.internet.ContentType。（ContentType.java:102）為null ）的javax.mail.internet.MimeBodyPart.updateHeaders（MimeBodyPart.java:1021）的javax.mail.internet.MimeMultipart.updateHeaders（MimeMultipart.java:419）的javax.mail.internet.MimeBodyPart.updateHeaders（MimeBodyPart.java： 13

private MimeBodyPart makeZipAttachment(AttachmentInfo attachmentInfo) throws IOException, MessagingException {
      ByteArrayOutputStream bos = null;
      ZipOutputStream zip = null;
      try
      {
         bos = new ByteArrayOutputStream();
         zip = new ZipOutputStream(bos);

         zip.putNextEntry(new ZipEntry(attachmentInfo.getName()));

         InputStream inputStream = attachmentInfo.getAttachment().getInputStream();
         byte[] buffer = new byte[1024];
         int len;
         while ((len = inputStream.read(buffer)) != -1) {
            zip.write(buffer, 0, len);
         }
         zip.closeEntry();
      }
      finally
      {
         if (bos != null)
            bos.close();
         if (zip != null)
            zip.close();
      }

      DataSource dataSource = new ByteArrayDataSource(bos.toByteArray(), "application/zip");
      MimeBodyPart mimeBodyPart = new MimeBodyPart();
      mimeBodyPart.setDataHandler(new DataHandler(dataSource));
      mimeBodyPart.setFileName(attachmentInfo.getName() + ".zip");
      mimeBodyPart.setHeader(CONTENT_TYPE, "application/zip");
      return mimeBodyPart;
   }

在我自己運行程序之前不能說太多，但是嘗試設置內容以及像mimeBodyPart.setContent這樣的內容
