二、项目介绍
项目描述这是一个基于SpringBootElectron框架开发的教务管理系统。首先这是一个前后端分离的项目前端采用VueElectron框架支持以Web界面访问也支持以桌面应用的形式访问。然后这项目代码简洁规范注释说明详细易于理解和学习。其次这项目功能丰富具有一个教务管理系统该有的所有功能。
项目功能此项目分为三个角色学生、老师和管理员。学生有管理个人信息、查看所有学期信息、查看个人课程和上课信息、查看个人成绩信息、查看公告信息和查看并支付个人缴费信息等等功能。老师有查看所有学生、老师和管理员信息、查看所有学院、专业和班级信息、查看所有学期信息、查看所有课程信息和查询上课信息、管理自己课程的成绩信息、查看公告信息和管理个人信息等等功能。管理员有管理所有学生、老师和管理员信息、管理所有学院、专业和班级信息、管理所有学期信息、管理所有课程信息和日程信息、查询上课信息、管理所有成绩信息、管理公告信息和管理所有缴费信息等等功能。
