微信小程序实现图书管理系统

作者主页：编程指南针

简介：Java领域优质创作者、CSDN博客专家 Java项目、简历模板、学习资料、面试题库、技术互助

文末获取源码

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
