文件无法删除.file在java tm SE库中打开

Question

尝试上传压缩的多部分文件。写在特定的位置。但无法删除该文件。解压后..尝试使用fileObj.delete但没有用!!

只是示例代码：

 DiskFileItemFactory factory = new DiskFileItemFactory();
        factory.setSizeThreshold(maxMemSize);

        // Create a new file upload handler
        ServletFileUpload upload = new ServletFileUpload(factory);
        upload.setSizeMax(maxFileSize);
        List fileItems = upload.parseRequest(request);

        // Process the uploaded file items
        Iterator i = fileItems.iterator();
        while (i.hasNext()) 
        {
            FileItem fi = (FileItem) i.next();
            if (!fi.isFormField())
            {
                fileName = FilenameUtils.getName(fi.getName());
                String contentType = fi.getContentType();
                long sizeInBytes = fi.getSize();
                logger.info("File name is::"+fileName);
                logger.info("content type is ::"+ contentType);
                logger.info("size is::"+sizeInBytes);

                // Write the file

                fileObj = new File(dirObj, clientFileName+".zip");
                fi.write(fileObj);
  return fileObj;

完成后，您必须关闭该文件。 Windows不允许删除打开的文件。
