Java畢業(yè)設計實戰(zhàn)之在線蛋糕銷售商城的實現(xiàn)

更新時間：2022年01月24日 16:06:21 作者：OldWinePot

這是一個使用了java+JSP+Springboot+maven+mysql+ThymeLeaf+FTP開發(fā)的在線蛋糕銷售商城，是一個畢業(yè)設計的實戰(zhàn)練習，具有線上蛋糕商城該有的所有功能，感興趣的朋友快來看看吧

一、項目簡述

功能：主頁顯示商品；所有蛋糕商品展示，可進行商品搜索；點擊商品進入商品詳情頁，具有立即購買功能，可增減購買商品數(shù)量亦可手動輸入，熱銷商品展示。立即購買進入確認訂單頁面，可選擇已經(jīng)添加的地址，亦可新增地址。可選擇購買哪些商品，可刪除不需要的商品。點擊結(jié)算進入確認訂單頁面，確認后提交訂單。后臺管理：(修改密碼等)，商品管理（商品批量添加、上下架等），訂單管理。

二、項目運行

環(huán)境配置：

Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）

項目技術：

JSP +Springboot+ SpringMVC + MyBatis + ThymeLeaf + FTP+ JavaScript + JQuery + Ajax + maven等等

登錄控制層：

@WebServlet(name = "user_login",urlPatterns = "/user_login")
public class UserLoginServlet extends HttpServlet {
    private UserService uService = new UserService();
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String ue = request.getParameter("ue");
        String password = request.getParameter("password");
        User user = uService.login(ue, password);
        if(user==null) {
            request.setAttribute("failMsg", "用戶名、郵箱或者密碼錯誤，請重新登錄！");
            request.getRequestDispatcher("/user_login.jsp").forward(request, response);
        }else {
            request.getSession().setAttribute("user", user);
            request.getRequestDispatcher("/user_center.jsp").forward(request, response);
        }
    }
 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 
    }
}

商品信息列表：

@WebServlet(name = "goods_List",urlPatterns = "/goods_list")
public class GoodsListServlet extends HttpServlet {
    private GoodsService gService=new GoodsService();
    private TypeService tService=new TypeService();
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 
    }
 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        int id=0;
        if(request.getParameter("typeid")!=null)
        {
            id=Integer.parseInt(request.getParameter("typeid"));
        }
        int pageNumber=1;
        if(request.getParameter("pageNumber")!=null) {
            try {
                pageNumber=Integer.parseInt(request.getParameter("pageNumber"));
            }
            catch (Exception e)
            {
 
            }
 
        }
        Type t=null;
        if(id!=0)
        {
            t=tService.selectTypeNameByID(id);
        }
        request.setAttribute("t",t);
        //List<Goods> list=gService.selectGoodsByTypeID(id,1,8);
        //request.setAttribute("goodsList",list);
        if(pageNumber<=0)
            pageNumber=1;
        Page p=gService.selectPageByTypeID(id,pageNumber);
 
        if(p.getTotalPage()==0)
        {
            p.setTotalPage(1);
            p.setPageNumber(1);
        }
        else {
            if(pageNumber>=p.getTotalPage()+1)
            {
                p=gService.selectPageByTypeID(id,p.getTotalPage());
            }
        }
 
        request.setAttribute("p",p);
        request.setAttribute("id",String.valueOf(id));
        request.getRequestDispatcher("/goods_list.jsp").forward(request,response);
    }
}

管理員訂單服務類：

@WebServlet(name = "admin_order_list",urlPatterns = "/admin/order_list")
public class AdminOrderListServlet extends HttpServlet {
    private OrderService oService = new OrderService();
    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        int status = 0;
        if(request.getParameter("status") != null) {
            status=Integer.parseInt(request.getParameter("status") ) ;
        }
        request.setAttribute("status", status);
        int pageNumber = 1;
        if(request.getParameter("pageNumber") != null) {
            try {
                pageNumber=Integer.parseInt(request.getParameter("pageNumber") ) ;
            }
            catch (Exception e)
            {
 
            }
        }
        if(pageNumber<=0)
            pageNumber=1;
        Page p = oService.getOrderPage(status,pageNumber);
        if(p.getTotalPage()==0)
        {
            p.setTotalPage(1);
            p.setPageNumber(1);
        }
        else {
            if(pageNumber>=p.getTotalPage()+1)
            {
                p = oService.getOrderPage(status,pageNumber);
            }
        }
 
        request.setAttribute("p", p);
        request.getRequestDispatcher("/admin/order_list.jsp").forward(request, response);
    }
}
