篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了微信小程序实现图书管理系统相关的知识，希望对你有一定的参考价值。
项目编号：BS-XCX-001
项目描述
系统使用SSM框架开发图书管理的后台管理接口功能，小程序通过接口进行调用显示，并提供给客户相应的处理操作功能，主要包括图书的增删改查功能
运行环境
Jdk8+tomcat8+mysql5.7+eclipse或IDEA+微信小程序
项目技术(必填)
spring+spring mvc+mybatis+微信小程序
下面展示一下系统的相关功能：
发布图书
图书列表
根据相关条件进行搜索
图书修改
个人中心
信息管理
前端微信小程序工程结构
后台工程结构
