基于SpringBoot的在线学习交流系统介绍
基于SpringBoot的在线学习交流系统是一个功能完善的教育管理平台，采用当前主流的Java技术栈进行开发，后端基于Spring Boot框架整合Spring、SpringMVC和MyBatis实现业务逻辑处理，前端采用Vue.js配合ElementUI组件库构建现代化用户界面，数据存储使用MySQL数据库，整体采用B/S架构模式确保系统的稳定性和可维护性。该系统涵盖了完整的在线教育生态链，包括系统主页展示、教师信息管理、学生信息维护、课程分类整理、学习资源共享、学习数据分析、学生成绩统计、举报记录处理等核心功能模块，同时集成了试题库管理、论坛分类讨论、试题智能管理、敏感词过滤、学习交流互动、反馈建议收集等增值服务，更重要的是系统还提供了完善的课程测试管理、系统后台管理以及考试管理等功能，形成了从课程发布、学习跟踪、在线测试到成绩评定的完整学习闭环，不仅能够满足教师的教学管理需求，也为学生提供了便捷的学习交流平台，通过论坛功能促进师生互动和学生之间的学术讨论，通过智能化的学习分析功能帮助教师了解学生学习进度，为个性化教学提供数据支撑，整个系统界面友好、操作简便、功能齐全，是计算机专业学生毕业设计的优质选择。
