        pagequeryutil pageutil = new pagequeryutil(params);
        request.setattribute("pageresult", newbeemallgoodsservice.searchnewbeemallgoods(pageutil));
        return "mall/search";
    }
 
    @getmapping("/goods/detail/{goodsid}")
    public string detailpage(@pathvariable("goodsid") long goodsid, httpservletrequest request) {
        if (goodsid < 1) {
            return "error/error_5xx";
        }
        newbeemallgoods goods = newbeemallgoodsservice.getnewbeemallgoodsbyid(goodsid);
        if (goods == null) {
            return "error/error_404";
        }
        newbeemallgoodsdetailvo goodsdetailvo = new newbeemallgoodsdetailvo();
        beanutil.copyproperties(goods, goodsdetailvo);
        goodsdetailvo.setgoodscarousellist(goods.getgoodscarousel().split(","));
        request.setattribute("goodsdetail", goodsdetailvo);
        return "mall/detail";
    }
 
}
