xheditor-文件上传-Spring3 MVC-支持html5-application/octet-stream
xheditor1.1.5 版本文件上传使用html5-application/octet-streamSpring3 MVC之前写的上传程序无法支持
@RequestMapping(value = "/upload") public String uploadFile(Model m, MultipartHttpServletRequest request) throws IOException { String path = UploadController.class.getResource("/").getPath().split("WEB-INF") + "upload/"; Iterator<String> iterator = request.getFileNames(); while (iterator.hasNext()) { String next = iterator.next(); List<MultipartFile> files = request.getFiles(next); for (int i = 0; i < files.size(); i++) { if (!files.get(i).isEmpty()) { byte[] bytes = files.get(i).getBytes(); String uploadFile = UploadUtils.generateFilename(path, UploadUtils.getExtension(files.get(i).getOriginalFilename(), "jpg")); File file = new File(uploadFile); FileOutputStream fos = new FileOutputStream(file); fos.write(bytes); fos.close(); m.addAttribute("url", uploadFile.replace(path, "/upload")); m.addAttribute("local", uploadFile); } } } return "upload"; }
需要改造如下：
@RequestMapping(value = "/upload", method = RequestMethod.POST) public String upload(Model m, HttpServletRequest request) throws IOException { String path = UploadController.class.getResource("/").getPath().split("WEB-INF") + "upload/"; if ("application/octet-stream".equals(request.getContentType())) { //HTML 5 上传 try { String dispoString = request.getHeader("Content-Disposition"); int iFindStart = dispoString.indexOf("filename =\"") + 10; int iFindEnd = dispoString.indexOf("\"", iFindStart); String sFileName = dispoString.substring(iFindStart, iFindEnd); int i = request.getContentLength(); byte buffer[] = new byte; int j = 0; while (j < i) { //获取表单的上传文件 int k = request.getInputStream().read(buffer, j, i - j); j += k; } if (buffer.length >= 0) { //文件是否为空 String uploadFile = UploadUtils.generateFilename(path, UploadUtils.getExtension(sFileName, "jpg")); File file = new File(uploadFile); OutputStream out = new BufferedOutputStream(new FileOutputStream(file, true)); out.write(buffer); out.close(); m.addAttribute("url", uploadFile.replace(path, "/upload")); m.addAttribute("local", uploadFile); } } catch (Exception ex) { m.addAttribute("err", ex.getMessage()); } } return "upload"; }
