Java 實(shí)戰(zhàn)練手項(xiàng)目之校園超市管理系統(tǒng)的實(shí)現(xiàn)流程
更新時(shí)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(xué)書上的理論是遠(yuǎn)遠(yuǎn)不夠的，只有在實(shí)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(shí)現(xiàn)一個(gè)校園超市管理系統(tǒng),大家可以在過程中查缺補(bǔ)漏，提升水平
前端模板框架為Bootstrap,系統(tǒng)分為前臺(tái)和后臺(tái)。后臺(tái)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(huì)員管理、管理員管理等。前臺(tái)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(gè)人中心等。該系統(tǒng)總共9張表
運(yùn)行環(huán)境：windows/linux、jdk1.8、mysql5.x、maven3.5\3.6、tomcat7.0
