基于Java实现考试管理系统

目录

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）。

项目北京it培训机构技术

springboot + maven + jpa+ vue 等等组成，b/s模式 + maven管理等等。
