根据goodsId获得相关商品的列表

List<Goods> goodsList = goodsDetailService.getGoodsListByproductId(productId);
        for (Goods goods2 : goodsList) {
            GoodsStand gs = goodsDetailService.getGoodsStandByGoodsId(goods2.getGoodsId());
            String stand = "";
            if (gs != null) {
                String[] ids = gs.getStandValueIds().split(",");
                String[] standNames = gs.getProductStandardNames().split(",");
                String[] standType = gs.getStandardTypes().split(",");
                if (gs.getStandardValues() != null) {
                    String[] standValues = gs.getStandardValues().split(",");
                }
                String[] valueNames = gs.getStandardValueNames().split(",");
                for (int i = 0; i < ids.length; i++) {
                    // stand+=(standNames[i]+":");
                    stand += (valueNames[i] + " ");
                }
                isStand = true;
            }
            goods2.setStand(stand);
            // System.out.println(stand);
        }
