2、错误原因

String fileName = item.getName();
File remoteFile = new File(new String(item.getName().getBytes(), "GBK"));
byte[] data = item.get();
/**
  * 获取文件上传路径
  */
String uploadFolder = getServletConfig().getInitParameter("uploadFolder");
String fileFolderName = getServletContext().getRealPath(uploadFolder + "\" + remoteFile);

3、解决办法
