同学好，咱们做了呀

private Result<List<ProductCategory>> getProductCategoryList(HttpServletRequest request) {
		Shop currentShop = (Shop) request.getSession().getAttribute("currentShop");
		List<ProductCategory> list = null;
		if (currentShop != null && currentShop.getShopId() > 0) {
			list = productCategoryService.getProductCategoryList(currentShop.getShopId());
			return new Result<List<ProductCategory>>(true, list);
		} else {
			ProductCategoryStateEnum ps = ProductCategoryStateEnum.INNER_ERROR;
			return new Result<List<ProductCategory>>(false, ps.getState(), ps.getStateInfo());
		}
	}
