Java 实战练习之网上电商项目的实现

一、项目简述

本系统功能包括： 一款基于Springboot+Vue的电商项目，前后端分离项目，前台后台都有，前台商品展示购买，购物车分类，订 单查询等等，后台商品管理，订单管理，信息维护，用户管理等等。

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX (Webstorm也 行)+ Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts都支 持)。

项目技术： Springboot + Maven + Mybatis + Vue + Redis^K, B/S 模式+ Maven等等，附带支付宝沙箱环境以及支付环节代码。
