java端同時獲取批量上傳圖片及其他數據

Controller層：

@ResponseBody
     @RequestMapping(value = "", method = RequestMethod.POST)
     public JSONObject addTroubleTicket(HttpServletRequest request,
                                        @RequestParam(value="accessToken",required=true)String accessToken,
                                        TroubleTicket troubleTicket,
                                        @RequestParam(value="file",required=false) MultipartFile[] images) throws Exception{
        troubleTicketReportService.addTroubleTicket(troubleTicket, images, accessToken);
        return returnSuccess();
    }

ps：圖片表單提交，所以不能用@RequestBody接收參數，可以用對象接收。
