Controller层：
@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：图片表单提交，所以不能用@RequestBody接收参数，可以用对象接收。
