基于java教室设备管理系统

项目获取请看文章最底下官网

教室设备管理系统是基于java编程语言和mysql数据库，ssh框架，bs的架构开发，系统主要分为学生，教师，管理员三个角色，其中学生可以登录系统，查看个人信息，在线借用教室设备；教师可以预约教师和借用教室设备；管理员可以对用户，教室，设备，通知信息进行管理，查看用户的预约信息。本设计适合作为java毕业设计和java课程设计来参考和学习。

一.技术环境

JDK版本：1.8
IDE工具：eclipse
数据库: mysql 5.6
编程语言: Java
tomcat: 8.0
框架：ssh
详细技术：HTML+CSS+JS+JSP+JAVA+SSH+MYSQL
