如何用java做一个教务系统 基于java的教务系统

基于javaweb+jsp的教务管理系统(java+JSP+Spring+SpringBoot+layui+maven)
一、项目简述

功能包括：
三角色教师 管理员，学生教务管理系统，包括院系管理，课题综合管理，信息管理，以及差旅管理，学生选题等等。

二、项目运行

环境配置：
Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）

项目技术：

JSP +Spring + SpringBoot + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等

适用

课程设计，大作业，毕业设计，项目练习，学习演示等
