Controller调用代码

    @RequestMapping(value="/exportDeliveryTradeQuery")
    public ModelAndView exportDeliveryTradeQuery(HttpServletRequest request, HttpServletResponse response,@ModelAttribute DeliveryTradeQuery query,ModelMap model){

        DeliveryTradeQueryExportExcel excel = new DeliveryTradeQueryExportExcel();
        BasicUserInfo basicUserInfo = SSOUtil.getUserInfo(request, response, false);
        String userId = basicUserInfo == null ? "" : basicUserInfo.getUserId();
        return new ModelAndView(excel,"data",list)
                .addObject("deliveryType", query.getDeliveryType())
                .addObject("isWsAccount", merchantService.isWsAccount(userId));
    }
