电商商城定制开发网上蛋糕商城JSP页面

电商商城定制开发首先是一个注册页面：

视图如下：

（不知道为什么在注册页面不显示头标题，是不是没有把CSS加进去？）

注册完之后点击注册后进入登录界面

登录界面为：

 代码为：

  1. <%@ page language="java" contentType="text/html; charset=UTF-8"
  2.     pageEncoding="UTF-8"%>

这个页面用的头部和尾部也是上面的那两个代码；

之后输入用户名和密码，因为没有与数据库连接，此时还只能用自定义一个用户名和密码来进行判断是否正确，正确的话进入购买界面，失败会提醒用户名或者密码错误，会提醒重新登录，如果成功的话会弹出

 然后3秒后跳转到购买首页，会让选择购买蛋糕还是退出登录，点击购买蛋糕会出现，点击购买就会提醒购买了什么蛋糕；

具体代码如下：

蛋糕的一个封装代码：

 

  1. package test;
  2. public class Cake {
  3.     private static final long serialVersionUID = 1L;
  4.     private String id;
  5.     private String name;
  6.     public Cake() {
  7.     }
  8.     public Cake(String id, String name) {
  9.         this.id = id;
  10.         this.name = name;
  11.     }
  12.     public String getId() {
  13.         return id;
  14.     }
  15.     public void setId(String id) {
  16.         this.id = id;
  17.     }
  18.     public String getName() {
  19.         return name;
  20.     }
  21.     public void setName(String name) {
  22.         this.name = name;
  23.     }
  24. }

 蛋糕的选择代码：

  1. package test;
  2. import java.util.Collection;
  3. import java.util.LinkedHashMap;
  4. import java.util.Map;
  5. public class CakeDB {
  6.     private static Map<String, Cake> cake = new LinkedHashMap<String, Cake>();
  7.     static {
  8.         cake.put("1", new Cake("1", "A类蛋糕"));
  9.         cake.put("2", new Cake("2", "B类蛋糕"));
  10.         cake.put("3", new Cake("3", "C类蛋糕"));
  11.         cake.put("4", new Cake("4", "D类蛋糕"));
  12.         cake.put("5", new Cake("5", "E类蛋糕"));
  13.     }
  14.     // 获得所有的蛋糕
  15.     public static Collection<Cake> getAll() {
  16.         return cake.values();
  17.     }
  18.     // 根据指定的id获蛋糕
  19.     public static Cake getCake(String id) {
  20.         return cake.get(id);
  21.     }
  22. }

判断是否购买蛋糕代码：

  12.             throws ServletException, IOException {
  13.         resp.setContentType("text/html;charset=utf-8");
  14.         PrintWriter out = resp.getWriter();
  15.         // 变量cart引用用户的购物车
  16.         List<Cake> cart = null;
  17.         // 变量pruFlag标记用户是否买过商品
  18.         boolean purFlag = true;
  19.         // 获得用户的session
  20.         HttpSession session = req.getSession(false);
  21.         // 如果session为null，purFlag置为false
  22.         if (session == null) {
  23.             purFlag = false;
  24.         } else {
  25.             // 获得用户购物车
  26.             cart = (List) session.getAttribute("cart");
  27.             // 如果用的购物车为null，purFlag置为false
  28.             if (cart == null) {
  29.                 purFlag = false;
  30.             }
  31.         }
  32.         /*
  33.          * 如果purFlag为false，表明用户没有购买蛋糕  重定向到ListServlet页面
  34.          */
  35.         if (!purFlag) {
  36.             out.write("对不起！您还没有购买任何商品！<br>"+"<a href='CakeDB.java'>重新购买---</a>"+"<a href='CakeDB.java'>或重新登录</a>");
  37.         } else {
  38.             // 否则显示用户购买蛋糕的信息
  39.             out.write("您购买的蛋糕有：<br>");
  40.             double price = 0;
  41.             for (Cake cake : cart) {
  42.                 out.write(cake.getName() + "<br>");
  43.             }
  44.         }
  45.         //response.sendRedirect("/JSP/LastAccessServlet1")
  46.     }
  47. }
