Java如何实现女装商城系统

这篇文章将为大家详细讲解有关Java如何实现女装商城系统，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

一、项目简述功能

javaweb 网上商城系统，前台＋后台管理，用户注册，登录，上哦展示，分组展示，搜索，收货地址管理，购物车管理，添加，购买，个人信息修改。订单查询等等，后台商品管理，分类管理，库存管理，订单管理，用户管理，信息修改等等．

二、项目运行

环境配置： Jdk1.8 + Tomcats . 5 + mysql + Eclispe ( IntelliJ IDEA ，Eclispe , MyEclispe , sts 都支持）

项目技术： JSP + Spring + SpringMVC + MyBatis + html + cSS + Javascript + JQuery + Ajax + layui + maven 等等。
