简介:分享计算机知识、学习路线、系统源码及教程
文末获取源码
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
- 用idea打开项目
- 在idea中配置jdk环境
- 配置maven环境并下载依赖
- 配置tomcat8.0
- 新建数据库,导入数据库文件
- 在mysql.properties文件中将数据库账号密码改成自己本地的
- 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
