Jetbrains全系列IDE使用 1年只要46元 售后保障 童叟无欺
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:
