功能说明

基于javaweb+mysql的JSP+Servlet在线蛋糕商城系统(java+jsp+jdbc+mysql)

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
