页面效果：

访问：http://localhost:9999/webuploader

后台java代码：

    private static String FILENAME = "";


    @Value("${xdja.upload.file.path}") private String decryptFilePath; @Value("${xdja.upload.file.path.temp}") private String decryptFilePathTemp; @GetMapping("/webuploader") public String webuploader() { return "webupload"; } /** * 分片上传 * * @return ResponseEntity<Void> */ @PostMapping("/upload") @ResponseBody public ResponseEntity<Void> decrypt(HttpServletRequest request, @RequestParam(value = "file", required = false) MultipartFile file, Integer chunks, Integer chunk, String name, String guid) throws IOException { boolean isMultipart = ServletFileUpload.isMultipartContent(request); if (isMultipart) { if (file == null) { throw new ServiceException(ExceptionEnum.PARAMS_VALIDATE_FAIL); } System.out.println("guid:" + guid); if (chunks == null && chunk == null) { chunk = 0; } File outFile = new File(decryptFilePathTemp+File.separator+guid, chunk + ".part"); if ("".equals(FILENAME)) { FILENAME = name; } InputStream inputStream = file.getInputStream(); FileUtils.copyInputStreamToFile(inputStream, outFile); } return ResponseEntity.ok().build(); } /** * 合并所有分片 * * @throws Exception Exception */ @GetMapping("/merge") @ResponseBody public void byteMergeAll(String guid) throws Exception { System.out.println("merge:"+guid); File file = new File(decryptFilePathTemp+File.separator+guid); if (file.isDirectory()) { File[] files = file.listFiles(); if (files != null && files.length > 0) { File partFile = new File(decryptFilePath + File.separator + FILENAME); for (int i = 0; i < files.length; i++) { File s = new File(decryptFilePathTemp+File.separator+guid, i + ".part"); FileOutputStream destTempfos = new FileOutputStream(partFile, true); FileUtils.copyFile(s, destTempfos); destTempfos.close(); } FileUtils.deleteDirectory(file); FILENAME = ""; } } }

经过测试1.35G 分片上传大概需要30s
