更新時間：2022年01月18日 17:14:52 作者：qq_1334611189

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+JSP+maven+Mysql實現(xiàn)一個網(wǎng)上電子書城,大家可以在過程中查缺補漏，提升水平

項目描述： spring mvc +jsp實現(xiàn)的簡單書城項目，可以在支付寶沙箱內(nèi)實現(xiàn)支付

運行環(huán)境： jdk8+tomcat9+mysql+IntelliJ IDEA

項目技術： spring+spring mvc+mybatis+jsp+maven
