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());
}
