该文档描述了一个教育系统的后端管理模块，包括管理员登录、权限设置、班级与课程管理等功能。使用Java作为后端语言，集成IDEA开发环境，前端采用Vue，数据库为Mysql，提供了相关服务层代码示例。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

1.登录界面

登录界面分为学生，教师，教务管理员三个登录界面

2. 管理员（admin）权限

2.1 管理员添加界面

通过对数据库中数据admin数据表的增删改查进行管理员的添加

2.2 管理员的添加详情

对管理员进行对应的权限信息授权，点击以后进行相对应的数据填充

2.3 管理员系管理

2.4 管理员专业管理

2.5 管理员班级管理

2.6 课程管理

3.学生登录

3.1 课表展示

3.2成绩查询

4.开发环境

java后端--------------------------------------->idea

前端--------------------------------------------->Vue

数据库------------------------------------------>Mysql

可视化工具（数据库）--------------------->navicat

4.1 操作管理员功能代码
