//测试上传FSN文件
    	@RequestMapping("FSNUpload")
    	@ResponseBody
    	public JSONObject imgUpload(HttpServletRequest request) throws IllegalStateException, IOException {
    		JSONObject json = TestController.uploadImg(request, PropertiesUtil.getProperty("upload.path"));
    		return json;
    	}
    
    	public  static JSONObject uploadImg(HttpServletRequest request, String imgParentDir) {
    
    		JSONObject json = new JSONObject();
    		// 将当前上下文初始化给 CommonsMutipartResolver （多部分解析器）
    		CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(
    				request.getSession().getServletContext());
    		// 检查form中是否有enctype="multipart/form-data"
    		if (multipartResolver.isMultipart(request)) {
    			// 将request变成多部分request
    			MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
    			// 获取multiRequest 中所有的文件名
    			Iterator iter = multiRequest.getFileNames();
    
    			while (iter.hasNext()) {
    				// 一次遍历所有文件
    				MultipartFile file = multiRequest.getFile(iter.next().toString());
    				if (file != null) {
    					String serverPath = request.getSession().getServletContext().getRealPath(imgParentDir);
    					// imgParentDir(/upload/good/)
    					String filePath = new Date().getTime() + file.getOriginalFilename();
    					String path = serverPath + "/" + filePath;
    					// 上传
    					try {
    						file.transferTo(new File(path));
    						json.put("imgPath", imgParentDir + filePath);
    					} catch (IllegalStateException e) {
    						e.printStackTrace();
    					} catch (IOException e) {
    						e.printStackTrace();
    					}
    				}
    
    			}
    
    		}
    		return json;
    
    	}
