//文件上传统一处理
        @RequestMapping(value = "/upload",method=RequestMethod.POST)
        @ResponseBody
        public WangEditor uploadFile(
                @RequestParam("myFile") MultipartFile multipartFile,
                HttpServletRequest request) {

                        .getRealPath("");
                InputStream inputStream = multipartFile.getInputStream();
                String contextPath = request.getContextPath();
                // 服务器根目录的路径
                String path = realPath.replace(contextPath.substring(1), "");
                // 根目录下新建文件夹upload，存放上传图片
                String uploadPath = path + "uploaded/";*/
                // 获取文件名称

                InputStream inputStream = multipartFile.getInputStream();
                String originalFilename = multipartFile.getOriginalFilename();
                String extSign = originalFilename.substring(originalFilename.lastIndexOf("."));
                String newFilename = UUID.randomUUID().toString() + extSign;
