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-plus

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

系统主要分为两个角色：管理员和普通用户。

1.普通用户(小程序)：登录、注册、首页、搜索图书、借阅、收藏、图书分类、座位查询与预订、我的收藏、借阅查询、退出登录等功能。

2.管理员(后台)：登录、首页、用户管理、图书分类、借阅管理、图书管理、阅览室管理、座位管理、收藏管理、系统管理(管理员管理、角色管理、菜单管理、系统日志)、退出登录、修改密码等功能的管理
