# 整个项目的架构文档

## 1. 技术选型
- 前端：Vue3 + Vite + Element Plus；移动端：小程序原生或 UniApp
- 后端：Spring Boot/Cloud；鉴权：OAuth2/OIDC；数据库：MySQL；缓存：Redis；消息队列：Kafka/Redis Stream

## 2. 总体架构图

API --> S3[File Service]
S1 --> DB[(MySQL)]
S2 --> DB
S2 --> Cache[(Redis)]
S2 --> MQ{{MQ}}
S3 --> OSS[(Object Storage)]
```

## 3. 部署视图

```

## 4. 风险与策略
- 性能瓶颈：缓存、异步化、读写分离、限流与降级
- 单点故障：多副本、健康检查、熔断与重试
- 安全漏洞：统一鉴权、输入校验、审计日志、密钥安全
