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

        Subject subject = SecurityUtils.getSubject();

        //如果获取不到用户名就是登录失败,但登录失败的话,会直接抛出异常
        subject.login(token);
