摘要本文设计并实现了高校作业提交与在线批改系统。系统面向管理员、教师与学生三类角色覆盖课程班级管理、作业发布、在线提交与版本追溯、教师批改与迟交自动扣分、学生互评、成绩查询、公告消息及基于火山方舟AI大模型的辅助批改、学情总结与作业要求润色等功能。采用 Spring Boot、MyBatis-Plus、JWT、Vue 3、Element Plus、MySQL 等技术完成前后端分离实现。需求分析明确多角色权限边界与作业全流程系统设计给出总体架构、数据库表结构与 REST 接口并对迟交扣分、提交版本追溯、AI 辅助教学等重点给出实现说明。经功能与流程测试主要业务可闭环运行能够支撑高校课程作业数字化管理与答辩演示。需求分析明确管理员、教师、学生的权限边界与核心业务流程系统设计给出总体架构、数据库表结构与REST接口划分并对系统重点业务模块的实现思路进行说明。经功能与流程测试验证主要业务可闭环运行能够支撑高校作业提交与在线批改系统的演示与应用需求为同类信息化系统建设提供参考。技术栈 Spring Boot 3 MyBatis-Plus MySQL Vue 3 Element Plus AI大模型数据库表14张创新点迟交自动扣分、提交版本追溯、AI大模型辅助批改与学情润色演示视频高校作业提交与在线批改系统文末获取联系文末获取联系作者介绍专注计算机编程个人开发坚持原创非工作室源码全网唯一。✅技术主流SpringBoot Vue 前后端分离MySQLAI大模型可本地运行✅配套资料源码 数据库 实验报告/论文 答辩 PPT部署演示远程调试问题解答技术范围SpringBoot、Vue、数据可视化、小程序、HLMT、Nodejs、uni-app、MySQL数据库、ElementUi等设计与开发。适用范围软件工程、软件技术、计算机科学与技术、大数据、云计算、JavaWeb开发、JavaEE、Java、Web应用开发、动态网页设计、小程序的毕设参考开发文档创新点说明、功能需求分析、数据库表结构设计、后端接口设计、创新点代码分析功能展示学生学生功能菜单名称1首页2作业中心3公告通知4提交记录5成绩查询6作业互评7系统消息教师教师功能菜单名称功能描述1数据统计查看学生、教师、作业、提交与迟交等汇总指标及图表把握教学运行概况。2作业管理发布与编辑作业要求、截止时间、满分与迟交规则支持 AI 润色作业要求。3学情分析按作业生成班级学情总结展示提交、批改、迟交与成绩统计及 AI 分析结论。4提交批改查看学生提交与版本历史参考互评后在线评分、填写评语批注可调用 AI 批改建议。5互评管理下达互评任务、查看互评结果为教师批改提供同伴评价参考。管理员管理员功能菜单名称1数据统计2班级管理3作业管理4学情分析5提交批改6提交规则7互评管理8公告管理9教师管理10学生管理11管理员账号数据库及架构系统数据库设计为数据库设计SET NAMES utf8mb4;
