文末获得源码

 项目编号：BS-XX-215

一，环境介绍

语言环境：Java:  jdk1.8

数据库：Mysql: mysql5.7

应用服务器：Tomcat:  tomcat8.5.31

开发工具：IDEA或eclipse

开发技术：Springboot和Vue

二，项目简介

项目基于Springboot和Vue开发实现了一套学校自习室预约管理平台。用户角色分为学生和管理员两类，学生注册登录后可以在线查看自习室、在校预约和举报、查看公告、在线交流、个人中心信息管理等；管理员登录可以进行学生管理、班级管理、自习室管理、预约管理、座位管理、签到管理、暂时离开管理和系统管理等模块。
