Java Online Exam在線考試系統(tǒng)的實現(xiàn)
更新時間：2021年11月23日 15:48:23 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+springboot+vue+jsp+mysql+maven實現(xiàn)Online Exam在線考試系統(tǒng),大家可以在過程中查缺補漏，提升水平
一、項目簡述
本系統(tǒng)主要實現(xiàn)的功能有： 學生以及老師的注冊登錄，在線考試，錯題查詢，學生管理，問題管理，錯題管理，錯題查詢，分數(shù)查詢，試卷管 理，人工組卷。自動組卷，教師，班級，統(tǒng)計等等管理功能。
二、項目運行
環(huán)境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
項目技術： VUE+Springboot+ SpringMVC + MyBatis + ThymeLeaf + JavaScript + JQuery + Ajax + maven等等
