Java 實戰(zhàn)練手項目之校園超市管理系統(tǒng)的實現(xiàn)流程
更新時間：2021年11月17日 08:55:40 作者：OldWinePot
讀萬卷書不如行萬里路，只學書上的理論是遠遠不夠的，只有在實戰(zhàn)中才能獲得能力的提升，本篇文章手把手帶你用java+SSM+Mysql+Maven+Bootstrap實現(xiàn)一個校園超市管理系統(tǒng),大家可以在過程中查缺補漏，提升水平
前端模板框架為Bootstrap,系統(tǒng)分為前臺和后臺。后臺主要為管理員角色，功能有：商品類型管理、商品管理、訂單管理、會員管理、管理員管理等。前臺用戶功能有：登錄、注冊、查看商品、加入購物車、付款、查看訂單、個人中心等。該系統(tǒng)總共9張表
運行環(huán)境：windows/linux、jdk1.8、mysql5.x、maven3.5\3.6、tomcat7.0
