commons-fileUpload组件解决文件上传乱码问题

response.setContentType("text/html; charset=UTF-8");
  
  Boolean isMultipart = ServletFileUpload.isMultipartContent(request);
  PrintWriter out = response.getWriter();
  if (isMultipart) {
   FileItemFactory fileItemFactory = new DiskFileItemFactory();
   ServletFileUpload servletFileUpload = new ServletFileUpload(fileItemFactory);
   servletFileUpload.setHeaderEncoding("UTF-8");//解决http报头乱码，即中文文件名乱码
   try {
    List<FileItem> list = servletFileUpload.parseRequest(request);
    for (Iterator<FileItem> iter = list.iterator(); iter.hasNext();) {
     FileItem item = iter.next();
     if (item.isFormField()) {
       out.println(item.getFieldName());
       out.println("<br/>");
       out.println("<br/>");
       out.println(item.getString("UTF-8")); //解决表单输入输乱码。
     }
     else{
      out.println(item.getFieldName());
      out.println(item.getName());
     }
    }
   } catch (Exception e) {
    //throw new BusinessException(" 出现文件上传错误。 ");
    System.out.println(" 出现文件上传错误。 ");
   }
