Question

我对韩国的egovframework有问题。下载文件时，恢复功能不起作用。为了进行比较，我转到了Oracle主页并比较了下载，但是在Oracle中启用了暂停恢复功能，但是在我的文件中禁用了暂停按钮。我已经编写了以下代码，这是什么问题？



@RequestMapping(value = "/cmm/fms/FileDown.do")
    public void cvplFileDownload(@RequestParam Map commandMap, HttpServletRequest request, HttpServletResponse response) throws Exception {

    String atchFileId = (String) commandMap.get("atchFileId");
    String fileSn = (String) commandMap.get("fileSn");

    //egovframework login security
    Boolean isAuthenticated = EgovUserDetailsHelper.isAuthenticated();

    if (isAuthenticated) {

        FileVO fileVO = new FileVO();
        fileVO.setAtchFileId(atchFileId);
        fileVO.setFileSn(fileSn);
        FileVO fvo = fileService.selectFileInf(fileVO);

        File uFile = new File(fvo.getFileStreCours(), fvo.getStreFileNm());
        long fSize = uFile.length();
        long start = 0;

        if (fSize > 0) {
            String mimetype = "application/x-msdownload";

            response.setHeader("Accept-Ranges", "bytes");


            if(request.getHeader("Range") != null){
                response.setStatus(HttpServletResponse.SC_PARTIAL_CONTENT);
                start = Long.parseLong(request.getHeader("Range").replaceAll("bytes=","").replaceAll("-", ""));
            }

            response.setHeader("Content-Length", new Long(fSize - start).toString());

            if(start != 0 ){
                response.setHeader("Content-Range", "bytes"
                            + new Long(start).toString()+"-"
                            + new Long(fSize - 1).toString()+"/"
                            + new Long(fSize).toString());
            }

            response.setContentType(mimetype);
            setDisposition(fvo.getOrignlFileNm(), request, response);

            BufferedInputStream in = null;
            BufferedOutputStream out = null;

            try {



                in = new BufferedInputStream(new FileInputStream(uFile));

                in.skip(start);
                byte[] b = new byte[1024];
                int i;
                while((i = in.read(b)) != -1){
                    response.getOutputStream().write(b,0,i);
                    response.flushBuffer();
                }
                in.close();
                //FileCopyUtils.copy(in, out);
                //out.flush();
            } catch (Exception ex) {
                LOGGER.debug("IGNORED: {}", ex.getMessage());
            } finally {
                if (in != null) {
                    try {
                        in.close();
                    } catch (Exception ignore) {
                        LOGGER.debug("IGNORED: {}", ignore.getMessage());
                    }
                }
                if (out != null) {
                    try {
                        out.close();
                    } catch (Exception ignore) {
                        LOGGER.debug("IGNORED: {}", ignore.getMessage());
                    }
                }
            }

        } else {
            response.setContentType("application/octet-stream");

            setDisposition(fvo.getOrignlFileNm()+"_오류", request, response);

            PrintWriter printwriter = response.getWriter();
            printwriter.println(fvo.getOrignlFileNm()+" 파일이 존재하지 않습니다.");
            printwriter.flush();
            printwriter.close();
        }
    }
}<code>

文件恢复功能在Spring中不起作用。
