Java 实战练手项目之校园超市管理系统的实现流程
更新时间：2021年11月17日 08:55:40 作者：OldWinePot
读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实战中才能获得能力的提升，本篇文章手把手带你用java+SSM+Mysql+Maven+Bootstrap实现一个校园超市管理系统,大家可以在过程中查缺补漏，提升水平
前端模板框架为Bootstrap,系统分为前台和后台。后台主要为管理员角色，功能有：商品类型管理、商品管理、订单管理、会员管理、管理员管理等。前台用户功能有：登录、注册、查看商品、加入购物车、付款、查看订单、个人中心等。该系统总共9张表
运行环境：windows/linux、jdk1.8、mysql5.x、maven3.5\3.6、tomcat7.0
