基于微信小程序图书馆座位预约管理系统

开发工具：IDEA、微信小程序

服务器：Tomcat9.0， jdk1.8

项目构建：maven

数据库：mysql5.7

前端技术：vue、uniapp

服务端技术：springboot+mybatis

本系统分微信小程序和管理后台两部分，项目采用前后端分离

项目功能描述：

1.微信小程序：登录、注册、主页、公告、轮播图、图书馆预约(座位选择、时间选择)，图书借阅、个人中心(预约状态、扫码签到、修改密码、设置、退出登录)

2.后台管理：登录、修改密码、系统管理(用户管理、角色管理、菜单管理、组织管理)、图书馆管理、座位管理、通知管理、预约管理、借阅管理、图书管理
