项目介绍
功能设计
管理员
1、用户管理
管理员可以新增、删除管理员
管理员可以删除学生
2、自习室管理
管理员可以新增自习室、设置自习室的座位数量、开放时间，对自习室进行管理
管理员可以管理学生的预订情况、可以强制退订
3、学院班级管理
管理员可以新增、修改、删除学院、班级(实际上这部分数据应该来源于教务系统)
4、个人管理
管理员可以对自己信息进行修改
学生
1、自习室管理
学生可以查看自习室座位的预定情况并进行预定
学生可以查看自己的预定情况，并退订
2、个人信息管理
学生可以修改自己的用户信息

环境要求
1.运行环境：最好是java jdk1.8,我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA,Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境：Tomcat7.x,8.X,9.x版本均可
4.硬件环境：windows7/8/10 4G内存以上；或者Mac OS;
5.是否Maven项目：是；查看源码目录中是否包含pom.xml;若包含，则为maven项目，否则为非maven.项目
6.数据库：MySql5.7/8.0等版本均可；
技术栈
-
MySQL5.7
-
Idea2020.3
-
SpringBoot、Mybatis-plus、thymeleaf
-
layui、jquery、xadmin
使用说明
1.使用Navicati或者其它工具，在mysql中创建对应sq文件名称的数据库，并导入项目的sql文件；
2.使用IDEA/Eclipse/MyEclipse导入项目，修改配置，运行项目；
3.将项目中config-propertiesi配置文件中的数据库配置改为自己的配置，然后运行；
