问题在于：

@ResponseBody  // 这里去掉
        @RequestMapping(params = "method=uploadFile")
        public void uploadFile(@RequestParam("file") List<MultipartFile> file, 
        	HttpServletRequest request, 
        	HttpServletResponse response // 添加
        ) {
    
            response.setContentType("text/html;chartset=UTF-8");  // 添加
            response.setCharacterEncoding("UTF-8"); // 添加
            //把文件放在部署路径下的用户ID文件夹中
            String webPath = request.getSession().getServletContext().getRealPath("/");
    
            String filePath = "uploaddir/";
    
            File dir = new File(webPath+filePath);
            if (!dir.exists()) {
                dir.mkdirs();
            }
    
            List<Map<String,Object>> resultList = new ArrayList<>();
            Map<String, Object> result = null;
            Map<String, Object> resultmap = new HashMap<>();
            try {
                for(MultipartFile myfile : file){
    
                    String filename = getFilename(myfile.getOriginalFilename());
                    String newFileName = System.currentTimeMillis() + filename.substring(filename.lastIndexOf("."));
                    String uuid= AppUtil.getUUID();
                    //上传文件
                    File tfile = new File(webPath+filePath, newFileName);
                    myfile.transferTo(tfile);
                    //将文件名和文件路径返回
                    result = new HashMap<String, Object>();
                    result.put("ID", uuid);// 文件添加一个ID
                    result.put("filename", filename);//原文件名
                    result.put("newFileName", newFileName);//新文件名
                    result.put("filepath", filePath + newFileName);//文件全路径
                    result.put("fullfilepath", webPath+filePath + newFileName);//文件全路径
    
                    resultList.add(result);
                }
                resultmap.put("success", "1");
                resultmap.put("list", resultList);
                response.getWriter().write(JSON.toJSONString(resultList)); // 添加
            } catch (IOException e) {
                resultmap.put("success", "0");
                logger.error(e.getMessage());
            }
            String str = JSON.toJSONString(resultmap, SerializerFeature.DisableCircularReferenceDetect);
            logger.debug("结果：{}", str);// debug 输出结果
    //        return str;   //  不能有返回值
        }

ajaxfileupload 不需要改什么东西
