Java 实战项目锤炼之在线蛋糕商城系统的实现
一、项目简述
功能: 主页显示热销商品;所有蛋糕商品展示,可进行商品搜 索;点击商品进入商品详情页,具有立即购买和加入购物 车功能,可增减购买商品数量亦可手动输入(同时验证库 存),热销商品展示。立即购买进入确认订单页面,可选择 已经添加的地址,亦可新增地址。(同时验证库存),可选 择购买哪些商品,可删除不需要的商品。点击结算进入确 认订单页面,确认后提交订单。后台管理:(修改密码 等),商品管理(商品批量添加、上下架等),订单管理。
二、项目运行
环境配置: Jdk1.8 + Tomcat8.5 + mysql + Eclispe ( IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
项目技术: JSP + C3P0+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload
用户登录模块代码:
用户登录模块: @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", "用户名、邮箱或者密码错误,请重新登录!"); 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 { } }
管理员添加用户代码:
管理员添加用户: @WebServlet(name = "admin_user_add",urlPatterns = "/admin/user_add") public class AdminUserAddServlet extends HttpServlet { private UserService uService = new UserService(); /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { User user = new User(); try { BeanUtils.copyProperties(user, request.getParameterMap()); } catch (IllegalAccessException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (InvocationTargetException e) { // TODO Auto-generated catch block e.printStackTrace(); } if(uService.register(user)) { request.setAttribute("msg", "客户添加成功!"); request.getRequestDispatcher("/admin/user_list").forward(request, response); }else { request.setAttribute("failMsg", "用户名或邮箱重复,请重新填写!"); request.setAttribute("u",user); request.getRequestDispatcher("/admin/user_add.jsp").forward(request, response); } } }
