> ### 前言 ###

基于springboot自动排课系统有三大用户：

学生：首页、教师信息、课程信息、公告信息、个人中心、后台管理。

管理员：首页、个人中心、学生管理、教师管理、班级信息管理、专业信息管理、教师信息管理、课程信息管理、排课信息管理、系统管理。

教师：首页、个人中心、课程信息管理、排课信息管理。

> ### 前台首页 ###

进入首页首先可以看到有首页、教师信息、课程信息、公告信息、个人中心、后台管理。![59fd2f68e05e4bec93e63e6818742e29.png][]

在教室信息中我们可以看到有教室信息![aa785d3243ee41d6a8ad4d8d35e6e3a9.png][]

查看教室详情信息![5596539743c341248653a9730e8c91c3.png][]

学生登录注册页面。![3cabf775426d4a3699cbc16bbdaaf483.png][]

在个人中心，学生可以查看自己的信息并且选择修改![ac1bedadeea84907b3bdad86652d56d1.png][]

> ### 管理员功能 ###

管理员和教师登录页面功能
