获得作为winmail.dat收到的POP 3的电子邮件附件 [英] get email attatchment for POP 3 received as winmail.dat

问题描述

当我尝试从POP 3邮件中获取附件时，我将其获取为winmail.dat，而不是原始的附加文件名.如何获取原始文件名?

When I try to get attatchment from POP 3 mail, I am getting them as winmail.dat, not the original attached file name. How can I get the original file name?

for (int i = 0; i < multipart.getCount(); i++) 
        {
            BodyPart bodyPart = multipart.getBodyPart(i);

            if(!Part.ATTACHMENT.equalsIgnoreCase(bodyPart.getDisposition())) 
            {
                //do something
            }
            else
            {
                bodyPart.getFileName(); // here only get the winmail.dat
            }   
        }

推荐答案

这是Exchange设置的一部分，可悲的是，您需要使用

This is part of the Exchange Settings, and sadly you going to need to extract the original contents from the WinMail.dat using JTNEF.

"Java TNEF软件包是TNEF消息处理程序的开放源代码实现，可以将其用作命令行实用程序或集成到基于Java的邮件应用程序中以提取原始消息内容."

可以在JavaMail的第三方工具上找到.

This is found on the JavaMail's third party tools.

作为替代方案，并且看起来更简单的是 POI-HMEF

As alternative and what looks simpler is POI-HMEF

样品提取:

public void extract(String winmailFilename, String directoryName) throws Exception {
   HMEFContentsExtractor ext = new HMEFContentsExtractor(new File(winmailFilename));

   File dir = new File(directoryName);
   File rtf = new File(dir, "message.rtf");
   if(! dir.exists()) {
       throw new FileNotFoundException("Output directory " + dir.getName() + " not found");
   }

   System.out.println("Extracting...");
   ext.extractMessageBody(rtf);
   ext.extractAttachments(dir);
   System.out.println("Extraction completed");
}

还有一个示例，用于打印内容

There is also a sample for printing the contents here.
