二、部分功能展示

☀️首页☀️

 ☀️商品展示☀️

  ☀️项目结构展示☀️

三、部分代码设计

3.1.商品推荐

  1. @WebServlet(name = "admin_goods_list",urlPatterns = "/admin/goods_list")
  2. public class AdminGoodsListServlet extends HttpServlet {
  3.     private GoodsService gService = new GoodsService();
  4.     /**

  6.      */
  7.     protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  8.         int type = 0;//推荐类型
  9.         if(request.getParameter("type") != null) {

  11.         }
  12.         int pageNumber = 1;
  13.         if(request.getParameter("pageNumber") != null) {
