Java项目:教材管理系统(java+SSM+jsp+mysql+maven)

源码获取：博客首页 "资源" 里下载！

一、项目简述

功能包括： 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。xcel的导入 导出操作。教U阿以领取入库的教材，可以退还教材。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等等。

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)

项目技术： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。
