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+Springboot+Maven+mybatis+Vue+Mysql實(shí)現(xiàn)學(xué)生管理系統(tǒng),大家可以在過程中查缺補(bǔ)漏，提升水平

一、項(xiàng)目簡述

本系統(tǒng)功能包括：學(xué)生管理，教師管理，課程管理，成績管理，系統(tǒng)管理等等。

二、項(xiàng)目運(yùn)行

環(huán)境配置：

Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX（Webstorm也行）+ Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）。

項(xiàng)目技術(shù)：

Springboot + Maven + mybatis+ Vue 等等組成，B/S模式 + Maven管理等等。
