Java 文创商城系统的实现流程

Java 文创商城系统的实现流程

一、项目简述

功能：本系统分用户前台和管理员后台。 前台展示+后台管理，前台界面可实现用户登录，用户注 册，商品展示，商品明细展示，用户信息修改，密码修 改，购物车添加，商品购买，商品结算，订单查询，购物 车查询，后台管理可实现商品管理，订单管理，用户管理

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 +Spring + SpringMVC + MyBatis + html+ css + javascript + jquery + Ajax + layui+ maven等等。
