Friends who are interested in the solution of downloading Chinese files in springmvc can follow the editor's train of thought to read it deeply. I hope it will be helpful to you after reading. Let's follow the editor to learn more about the solution of downloading Chinese files with underlined names in springmvc.

Springmvc download Chinese file name is underlined

In the springboot project, when downloading a file, the file stream is written to body by encapsulating ResponseEntity. This way of downloading the file causes the downloaded file name to be displayed as an underscore in the form of the body.

This problem is easy to solve.

Directly define the encoding format of the entered file name to GBK format

The code is as follows

Public static ResponseEntity export (File file) throws UnsupportedEncodingException {if (file = = null) {return null;} / / encodes the file name String fileName = new String (file.getName (). GetBytes ("GBK"), "ISO-8859-1"); HttpHeaders headers = new HttpHeaders (); headers.add ("Cache-Control", "no-cache, no-store, must-revalidate") Headers.add ("Content-Disposition", "attachment; filename=" + fileName); headers.add ("Pragma", "no-cache"); headers.add ("Expires", "0"); headers.add ("Last-Modified", new Date (). ToString ()); headers.add ("ETag", String.valueOf (System.currentTimeMillis () Return ResponseEntity .ok () .headers (headers) .contentLength (file.length ()) .contentType (MediaType.parseMediaType ("application/octet-stream")) .body (new FileSystemResource (file));} when java generates a file name, the Chinese characters become underlined? Public static void exportToExcel (String uid, String name, String htmlText, HttpServletRequest request, HttpServletResponse response) {htmlText = htmlText.replaceFirst (","); htmlText = htmlText.replaceAll ("", "); htmlText = htmlText.replaceFirst (", "); try (OutputStream out = response.getOutputStream ()) {String fileName = name+" _ "+ DateUtils.getNow (" yyyyMMddHHmmss ") / / fileName = new String (fileName.getBytes (), "utf-8") + ".xls"; if ("large" .equals (htmlText)) {ReportingPo report = reportingService.getByUid (uid); Map formParameters = generationService.getFormParameters (request.getParameterMap (), report.getDataRange ()); ReportTable reportTable = generationService.getReportTable (report, formParameters); htmlText = reportTable.getHtmlText () } / / response.reset (); response.addHeader ("Content-Disposition", "attachment;filename=" + new String (fileName.getBytes ("utf-8"), "iso-8859-1") + ".xls"); / / response.setHeader ("Content-Disposition", String.format ("attachment;filename=% s", fileName)); response.setContentType ("application/vnd.ms-excel; charset=utf-8") Response.setCharacterEncoding ("utf-8"); response.addCookie (new Cookie ("fileDownload", "true")); / / out.write (new byte [] {(byte) 0xEF, (byte) 0xBB, (byte) 0xBF}); / / generate utf8 file out.write (htmlText.getBytes ("utf-8")) with bom; out.flush () } catch (Exception ex) {throw new RuntimeException (ex);}} pay attention to the two codes new String (fileName.getBytes ("utf-8"), "iso-8859-1") + ".xls" for downloading Chinese files in springmvc. This is the end of the solution. I hope the above content can improve everyone. If you want to learn more knowledge, please pay more attention to the editor's updates.
