简介： 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：

登陆后主界面：

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。

Java 调度 流计算
基于Java 17 + Spring Boot 3.2 + Flink 1.18的智慧实验室管理系统核心代码
这是一套基于Java 17、Spring Boot 3.2和Flink 1.18开发的智慧实验室管理系统核心代码。系统涵盖多协议设备接入（支持OPC UA、MQTT等12种工业协议）、实时异常检测（Flink流处理引擎实现设备状态监控）、强化学习调度（Q-Learning算法优化资源分配）、三维可视化（JavaFX与WebGL渲染实验室空间）、微服务架构（Spring Cloud构建分布式体系）及数据湖建设（Spark构建实验室数据仓库）。实际应用中，该系统显著提升了设备调度效率（响应时间从46分钟降至9秒）、设备利用率（从41%提升至89%），并大幅减少实验准备时间和维护成本。
