网硕互联帮助中心大家好，我是Java1234_小锋老师，分享一套锋哥原创的LLM大模型 基于Spring AI 2.0的RAG AI智能办公OA系统(SpringBoot4+Vue3) 。
项目介绍
随着大语言模型（Large Language Model，LLM）技术的快速落地，企业办公自动化（Office Automation，OA）系统正从“表单驱动”转向“对话驱动”。传统OA虽然能够完成请假、报销、审批等流程，但员工仍需记忆制度条款、手工填写大量字段，并反复在多个菜单之间查询单据进度，沟通成本高、体验割裂。针对这一问题，本文设计并实现了一套面向大学与中小企业场景的AI智能办公OA系统，题目为“LLM大模型 基于Spring AI 2.0的AI智能办公OA系统”。
系统采用前后端分离架构。后端以 Java 17 为开发语言，基于 Spring Boot 4.0.8 构建 Web 服务，持久层使用 MyBatis-Plus 访问 MySQL 8 数据库 db_ai_oa；前端采用 Vue 3 + Vite + Element Plus + Pinia 实现响应式管理界面，工作台使用 ECharts 展示统计图表。智能能力以 Spring AI 2.0.1 为核心，通过 OpenAI 兼容接口对接阿里云百炼大模型：对话模型选用 qwen3.8-27b，嵌入模型选用 text-embedding-v4（维度 2048），向量检索使用 Redis Stack 的 RediSearch 模块，索引算法为 HNSW，距离度量为余弦相似度。
在业务层面，系统实现管理员、总经理、部门经理、普通员工四类角色的权限隔离。办公流程覆盖部门与员工管理、请假与报销两级审批、公告发布和个人中心。其中请假超过 3 天、报销超过 5000 元需总经理终审；部门经理本人请假直接进入总经理节点。在智能层面，系统提供三类核心能力：其一，自然语言智能填写请假单，模型将“下周三请一天事假”解析为结构化草稿，并调用假期余额工具给出扣薪提示；其二，企业知识库 RAG 问答，管理员可上传 txt、doc、pdf、markdown 制度文件，经 Tika 解析、Token 切片后写入向量库，回答时强制标注出处；其三，多轮对话助手结合 Chat Memory 与 Tool Calling，可查询真实请假/报销审批进度，避免大模型幻觉。
测试表明，系统功能完整、角色权限正确、审批阈值规则生效，AI 填单与制度问答能够稳定返回结构化结果和可追溯出处。本文工作验证了 Spring AI 2.0 在国产办公系统中的工程可行性，对同类毕业设计与企业信息化升级具有参考价值。
