一、项目介绍

教务管理系统基于Spring+SpringMVC+Mybatis开发，功能和学生成绩管理系统，学生选课管理系统类似，也可以做学生成绩管理系统，学生选课管理系统。系统分为管理员，教师，学生三种角色。

管理员功能如下：

• 课程管理
• 学生管理
• 教师管理

教师功能如下：

• 我的课程
• 成绩打分

学生功能如下：

• 查看课程
• 选课
• 退课
• 查看成绩

二、技术框架

• 后端：Spring，Springmvc，Mybatis
• 前端：bootstrap

三、安装教程

1. 用idea打开项目
2. 在idea中配置jdk环境
3. 配置maven环境并下载依赖
4. 配置tomcat8.0
5. 新建数据库，导入数据库文件
6. 在mysql.properties文件中将数据库账号密码改成自己本地的
7. 启动运行， 管理员账号密码 admin/123456，教师账号密码 1001/123456，学生账号密码 10001/123456
