利用javamail保存邮件附件时遇到的问题，解决了立刻给分

给你一个代码吧：
public String[] getpart(int i){
        int            m  = 0              ;
        String[] partname = null           ;

    try{
           folder.open(Folder.READ_WRITE);//READ_ONLY为打开方式
   message=folder.getMessages();
           int count=folder.getMessages().length;
           Object out_content = message[i].getContent();
           if (!(out_content instanceof Multipart)){//不是复合邮件体，既是带附件。
              partname = new String[0];
              return partname;
           }
           mp = (Multipart)out_content;
            m = mp.getCount();
          if (ispart(i)){

                                  }
                          try{
                                   int chunk = part.getSize();//获得附件的大小，不一定很准确。
                                   System.out.println("chunk=="+chunk);
                                   byte [] buffer = new byte[chunk];
                                   InputStream instream = part.getInputStream();
                                   instream.read(buffer,0,chunk);
                                   myFileoutputstream.write(buffer,0,chunk);
                                   instream.close();
                                   myFileoutputstream.close();
                               }catch(Exception e){
                                    setInfo("取得附件时异常："+e.toString());
                                    System.out.println("取得附件时异常："+e.toString());
                              }
                     }
                 }        }     return partname;
  }这是我处理附件是用到的。
看看对你有帮助吗？

用JAVA的类：com.sun.mail.util.* ,有对UUEncode编码方式解码的类！
你自己找找吧！
还有一个包里也有：sun.misc.*!
你自己找一下吧！
我也遇到过这个问题，通过
String str=new String(xxx.getBytes(),"gb2312");解决了：最是中文的附件名称我没有转换过来，好像是javamail内部机制的问题！
我把文件名称用系统时间+附件编号,
我的QQ：24560795, 多交流！
哦，是个windowsxp pro的图片
总算开完会了我没明白你的意思，是不是要把一个email文件的附件读取出来？
如果是，继续：
首先你必须有一个 Message，可能是从pop3收下来的，也可以是从文件读出来的：
FileInputStream in = new FileInputStream(""yourmail.eml");
MimeMessage = new MimeMessage(session,in);
呵呵，现在就有一封email了，然后是把它发出去或者读取它的各个部分
别忘了判断是否是Multipart，如果是那么就获取多个part，一个一个保存。
失败..
用setDataHandler方法和setFilename方法都试过了，读取eml得到的message居然不是multipart的，可是我输出message的内容的确包含附件内容。正文和附件之间有三个0D0A，也没问题啊，不知道哪里有毛病，我再看看协议去。
这类邮件类型为：text/plain，我现在已经解决了这个问题，如果谁有什么类似的问题可以问我，如果我知道答案会尽量帮忙的。过几天我整理一下这个东西放上来，谢谢大家了。
简单总结一下：
1，得到其中的一个区块（附件）的偏移量以及该区块的大小；
2，得到一个InputStream: MimeMessage.getInputStream()；指到要保存区块的受部，InputStream.skip(long)；
3，构建一个UUDecoderStream：new UUDecoderStream(InputStream)；
4，得到附件的名字并保存附件：UUDecoderStream.getName()，最好使用new String(String.getBytes("iso-8859-1"))变换一下而得到原始名字；保存就相对简单了:
FileOutputStream out = new FileOutputStream(String);
int a = 0;
while((a = UUDecoderStream.read()) != -1)
out.write(a);
a.close();
5，回到第一步处理下一个附件，直到没有附件后退出。这就是这类邮件的处理办法，不是很复杂，如果谁有什么问题可以发邮件给我：[email protected]，不一定会回复的，呵呵个人意见，仅供参考。
