基于javaweb+jsp的网上商城系统(java+jsp+servlet+mysql+ajax)

一、项目简述（+需求文档+PPT）

功能： 主页显示热销商品；所有商品展示，可进行商品搜索；点 击商品进入商品详情页，显示库存，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，订单重复提交给予响 应，库存不足或商品下架给予响应。后台管理：（修改密码 等），商品管理（商品批量添加、上下架、库存维护等）， 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等等。
