jspsmartupload上传文件中文乱码

  采用jspsmartupload上传文件时，如果文件名含有中文，在服务器端取得文件名是会出现乱码。如果表单项中填写了中文，一样会有乱码问题。看了下jspsmartupload的源码，改了两个地方，现在可以没有乱码问题了。
  第一个地方，修改类SmartUpload中的upload()方法
 

public void upload()
      throws SmartUploadException, IOException, ServletException
  {
      int totalRead = 0;
      int readBytes = 0;
      long totalFileSize = 0L;
      boolean found = false;
      String dataHeader = new String();
      String fieldName = new String();
      String fileName = new String();
      String fileExt = new String();
      String filePathName = new String();
      String contentType = new String();
      String contentDisp = new String();
      String typeMIME = new String();
      String subTypeMIME = new String();
      boolean isFile = false;
      m_totalBytes = m_request.getContentLength();
      m_binArray = new byte[m_totalBytes];
      for(; totalRead < m_totalBytes; totalRead += readBytes)
          try
          {
              m_request.getInputStream();
              readBytes = m_request.getInputStream().read(m_binArray, totalRead, m_totalBytes - totalRead);
          }
          catch(Exception e)
          {
              throw new SmartUploadException("Unable to upload.");
          }

      for(; !found && m_currentIndex < m_totalBytes; m_currentIndex++)
          if(m_binArray[m_currentIndex] == 13)
              found = true;
          else
              m_boundary = m_boundary + (char)m_binArray[m_currentIndex];

      if(m_currentIndex == 1)
          return;
      m_currentIndex++;
      do
      {
          if(m_currentIndex >= m_totalBytes)
              break;
          dataHeader = getDataHeader();
          m_currentIndex = m_currentIndex + 2;
          isFile = dataHeader.indexOf("filename") > 0;
          fieldName = getDataFieldValue(dataHeader, "name");
          if(isFile)
          {
              filePathName = getDataFieldValue(dataHeader, "filename");
              fileName = getFileName(filePathName);
              fileExt = getFileExt(fileName);
              contentType = getContentType(dataHeader);
              contentDisp = getContentDisp(dataHeader);
              typeMIME = getTypeMIME(contentType);
              subTypeMIME = getSubTypeMIME(contentType);
          }
          getDataSection();
          if(isFile && fileName.length() > 0)
          {
              if(m_deniedFilesList.contains(fileExt))
                  throw new SecurityException("The extension of the file is denied to be uploaded (1015).");
              if(!m_allowedFilesList.isEmpty() && !m_allowedFilesList.contains(fileExt))
                  throw new SecurityException("The extension of the file is not allowed to be uploaded (1010).");
              if(m_maxFileSize > (long)0 && (long)((m_endData - m_startData) + 1) > m_maxFileSize)
                  throw new SecurityException(String.valueOf((new StringBuffer("Size exceeded for this file : ")).append(fileName).append(" (1105).")));
              totalFileSize += (m_endData - m_startData) + 1;
              if(m_totalMaxFileSize > (long)0 && totalFileSize > m_totalMaxFileSize)
                  throw new SecurityException("Total File Size exceeded (1110).");
          }
          if(isFile)
          {
              com.jspsmart.upload.File newFile = new com.jspsmart.upload.File();
              newFile.setParent(this);
              newFile.setFieldName(fieldName);
              newFile.setFileName(fileName);
              newFile.setFileExt(fileExt);
              newFile.setFilePathName(filePathName);
              newFile.setIsMissing(filePathName.length() == 0);
              newFile.setContentType(contentType);
              newFile.setContentDisp(contentDisp);
              newFile.setTypeMIME(typeMIME);
              newFile.setSubTypeMIME(subTypeMIME);
              if(contentType.indexOf("application/x-macbinary") > 0)
                  m_startData = m_startData + 128;
              newFile.setSize((m_endData - m_startData) + 1);
              newFile.setStartData(m_startData);
              newFile.setEndData(m_endData);
              m_files.addFile(newFile);
          } else
          {
              /**
               * 原来的代码
               * String value = new String(m_binArray, m_startData, (m_endData - m_startData) + 1);
               */
            /**
             * 2009-9-17 修改 ，解决取得request的参数的中文编码问题
             */
              String value = new String(m_binArray, m_startData, (m_endData - m_startData) + 1, "utf-8");


            m_formRequest.putParameter(fieldName, value);
          }
          if((char)m_binArray[m_currentIndex + 1] == '-')
              break;
          m_currentIndex = m_currentIndex + 2;
      } while(true);
  }

  第二个地方，修改类SmartUpload中的getDataHeader()方法

private String getDataHeader()
   {
       int start = m_currentIndex;
       int end = 0;
       int len = 0;
       boolean found = false;
       while(!found)
           if(m_binArray[m_currentIndex] == 13 && m_binArray[m_currentIndex + 2] == 13)
           {
               found = true;
               end = m_currentIndex - 1;
               m_currentIndex = m_currentIndex + 2;
           } else
           {
               m_currentIndex++;
           }


       //原始代码
       //String dataHeader = new String(m_binArray, start, (end - start) + 1);
       /**
        * 2008-9-17 解决文件名的中文乱码问题
        */
       String dataHeader = null;
    try {
        dataHeader = new String(m_binArray, start, (end - start) + 1,"utf-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
       return dataHeader;
   }
