教材管理系统
一、项目演示
基于SSM的教材管理系统
二、项目介绍
有三个角色
1、管理员
功能模块：用户管理、教材录入、供应商录入、教材入库、所有付款记录、教材热度分析
管理员可以增删改查教材、教材商、入库教材、用户（用户包括学生和教师）可以对教材商、教材进行excel的导入导出操作
2、教师
功能模块：教师领取教材、教师可以领取入库的教材，可以退还教材
3、学生
功能模块:学生领取教材、学生的教材、学生付款记录、学生只能在对应的教师那里领取教材，并且可以退还教材、查询自己已经领取的教材，并且对已领教材付款。
语言：java
框架：Spring、SpringMVC、Mybatis、layui、jquery、bootstrap
数据库：MySQL
三、系统部分功能截图
四、部分代码展示
