项目介绍

本系统分为三个角色：管理员、老师和学生
管理员功能如下：登录、班级信息管理、教师信息管理、教室信息管理、课程录入、课程排课、用户管理、专业信息管理、自动排课
老师功能如下：登录，查询排课
学生功能如下：登录，查询排课

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.是否Maven项目: 否；

6.数据库：MySql 5.7/8.0等版本均可；

技术栈

1. 后端：Spring Struts Hibernate

2. 前端：JSP+css+javascript+jQuery

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，配置项目；
3.将项目中WebRoot/WEB-INF/applicationContext.xml配置文件中的数据库配置改为自己的配置，然后运行；
4.登录地址：http://localhost:8080/schedule/login.jsp

5、登录账号：管理员 admin/123 老师 ls/123 学生 xs/123
