HtKnowledgeFileInfo是用来存储文件的controller层@PostMapping("/uploadFile")@ResponseBodypublic AjaxResult uploadFile(@RequestParam(value="file", required=false) MultipartFile file) throws IOException{ String filePath = Global.getUploadPath(); String nameType=file.getOriginalFilename(); String Name=nameType.substring(0,nameType.lastIndexOf(".")); HtKnowledgeFileInfo fileInfo=new HtKnowledgeFileInfo(); String fileName = null; try { fileName = FileUploadUtils.upload(filePath, file, DEFAULT_ALLOWED_EXTENSION); } catch (InvalidExtensionException e) { e.printStackTrace(); } fileInfo.setFilePath(fileName); fileInfo.setFileName(Name); return toAjax(fileInfoService.insertHtKnowledgeFileInfo(fileInfo));}HTML页面 <div class="col-sm-9"> <input id="uploadFile" name="uploadFile" type="f" multiple> <input type="button" onclick="uploadFile()" value="上传"> </div>javascript代码 function uploadFile(isno) { var formData = new FormData(); formData.append('fileId',$("#fileId").val()); formData.append('fileName', $("#fileName").val()); formData.append('file', $('#file')[0].files[0]); if (typeof($('#file')[0].files[0]) != 'undefined') { $.ajax({ url: ctx + "ht/invoice/uploadFile", type: 'post', cache: false, data: formData, async: false, processData: false, contentType: false, dataType: "json", }); }}这个功能是在点击名称弹出窗口显示详细信息，但是要在这个窗口中添加一个可以上传文件的功能。如果我的方法错了想请教大佬们怎么才能实现这个功能？？？？
