基于Javaweb实现实验室设备管理系统

基于Javaweb实现实验室设备管理系统

 项目编号：BS-XX-013

本项目基于JSP/Servlet技术实现开发，开发工具采用IDEA或ECLIPSE，数据库采用MYSQL数据库。

首次使用，需要进入src/com/util/DBOK 修改数据库的相关信息，系统设置mysql的用户名为root,密码为root,可以根据需要修改为自己的账户信息。

实验室设备管理系统主要包含两个用户角色，一个是超级管理员，可以进行系统的各种管理工作，一个是普通管理员，主要进入系统进行相应的信息查看工作。系统的主要功能包含有：登陆用户的信息修改，系统用户管理，使用设备的用户信息管理，实验设备管理，设备借出管理，设备维修管理，共建记录管理，实验室设备统计（图形报表的形式展示），注销退出，登陆系统。

下面就部分功能进行功能展示：

用户登陆：

登陆后主界面：

系统用户管理：

用户信息管理：

设备信息管理：

设备借出管理：

设备维修管理：

共建记录管理：

实验室设备统计：

以上是展示的系统部分功能，此项目功能完整，运行无误，比较适合毕业设计使用。

核心代码：
