Java畢業(yè)設(shè)計(jì)實(shí)戰(zhàn)之學(xué)生管理系統(tǒng)的實(shí)現(xiàn)
一、項(xiàng)目簡(jiǎn)述
本系統(tǒng)功能包括: 學(xué)生管理,教師管理,課程管理,成績(jī)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。
