本研究旨在设计并实现一个基于Java, Spring Boot和HTML的实验室预约管理系统,以解决实验室资源分配不均、管理混乱和预约流程繁琐等问题。系统采用B/S架构设计,后端使用Spring Boot框架进行开发,前端使用HTML进行页面设计,实现了用户登录、实验室预约、查看预约状态以及管理员对实验室的管理等功能。
首先,系统通过Spring Boot实现了快速开发和部署,简化了项目的配置和管理。同时,利用Spring Boot的自动装配特性,方便地集成了MyBatis、MySQL数据库等技术,实现了数据持久化存储。
其次,系统前端采用HTML进行页面设计,结合CSS和JavaScript实现了友好的用户界面。用户可以通过网页进行实验室预约,查看预约状态,取消预约等操作。同时,系统提供了管理员角色,管理员可以对实验室进行管理,如添加、修改实验室信息,查看所有预约记录等。
最后,系统采用了分层架构设计,将业务逻辑层、数据访问层和表示层分离,降低了模块间的耦合度,提高了代码的可维护性和可扩展性。此外,系统还实现了权限控制和异常处理机制,保证了系统的安全性和稳定性。
总之,本研究设计的基于Java, Spring Boot和HTML的实验室预约管理系统,不仅解决了实验室资源分配和管理的问题,还为用户提供了便捷的预约服务,具有较高的实用价值和推广前景。
实现的功能
管理员、教师、学生三种角色;
管理员:用户管理(学生管理、教师管理)、实验室管理、教务管理(班级管理、课程管理)、预约(个人预约、教师预约、预约列表、审核列表);
学生:实验室列表、预约(我的预约、个人预约);
教师:班级管理、实验室列表、预约(教师预约、我的预约)。
用户在预约的时候可以看到实验室的预约人数状态是否满了,也可以在实验室列表查看预约状态。
使用的技术
后端:JAVA开发语言,SpringBoot框架,MySql数据库,Maven;
前端:layUI框架、HTML页面。
