项目介绍

本项目为基于WEB的教务管理系统。
主要系统功能包括：
学生管理：显示所有学生、添加学生；
课程管理：显示所有课程、添加课程；
学院管理：显示所有学院、添加学院；
专业管理：所有专业、设置专业；

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
5.数据库：MySql 5.7版本；

6.是否Maven项目: 是

技术栈

1. 后端：servlet

2. 前端：JSP+css+javascript+layui

使用说明

1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，导入成功后请执行maven clean;
maven install命令，然后运行；
3. 将项目中util/ConnectionUtil.java修改数据库信息
4. 运行项目，在浏览器中输入http://localhost:8080/student-sys 登录
