项目简述

本系统功能包括：

支持单选题、多选题、判断题支持学生(student)、教师(teacher)、管理员(admin)三种角色学生：参加考试和查看我的考试教师：学生的所有权限+创建/编辑题目+创建/编辑考试管理员：教师的所有权限+管理用户。

项目运行

环境配置：

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

项目技术

Springboot + Maven + Jpa+ vue 等等组成，B/S模式 + Maven管理等等。
