**基于Spring Boot的家庭数字记忆智能管理与分享系统设计与实现**

随着家庭数字照片和视频数量的爆发式增长，传统存储方式面临分类混乱、检索困难、隐私泄露等问题。本文设计并实现了一个基于Spring Boot的家庭影像管理系统，通过人工智能与智能分类技术，构建安全、智能、便捷的家庭数字记忆管理平台。

### 一、系统架构设计

系统采用分层微服务架构，兼顾多媒体处理性能与家庭使用的易用性，确保数据安全与隐私保护。

**技术架构**：

- 后端框架：Spring Boot 2.7 + Spring Cloud + Spring Security

- 图像处理：OpenCV 4.5 + TensorFlow Lite（移动端AI）

- 数据存储：MySQL 8.0（元数据）+ MinIO（对象存储）+ Redis 7.0（缓存）

- 搜索引擎：Elasticsearch 7.17（内容检索）

- 人脸识别：FaceNet + ArcFace（人脸识别模型）

- 前端框架：Vue 3 + Vite + Element Plus

- 移动端：Flutter（跨平台应用）

**核心功能模块**：

1. 智能图像分类与人脸识别

2. 时空记忆地图与故事线构建

3. 隐私保护与家庭共享管理

4. 智能相册与回忆推送

5. 跨设备同步与备份管理
