# 存储 SPI
|
|
|
|
## SPI 接口
|
|
|
|
```java
|
|
public interface ObjectStorageService {
|
|
void store(String key, InputStream content, String contentType);
|
|
InputStream retrieve(String key);
|
|
void delete(String key);
|
|
boolean exists(String key);
|
|
}
|
|
```
|
|
|
|
## 内置实现
|
|
|
|
### LocalFileStorageService
|
|
|
|
本地文件系统实现，用于开发环境。
|
|
|
|
### S3StorageService
|
|
|
|
S3 协议兼容实现，支持：
|
|
- AWS S3
|
|
- MinIO
|
|
- 阿里云 OSS
|
|
- 腾讯云 COS
|
|
- 其他 S3 兼容存储
|
|
|
|
## 配置
|
|
|
|
```bash
|
|
# 选择存储提供方
|
|
SKILLHUB_STORAGE_PROVIDER=s3
|
|
|
|
# S3 配置
|
|
SKILLHUB_STORAGE_S3_ENDPOINT=https://s3.example.com
|
|
SKILLHUB_STORAGE_S3_BUCKET=skillhub
|
|
SKILLHUB_STORAGE_S3_ACCESS_KEY=xxx
|
|
SKILLHUB_STORAGE_S3_SECRET_KEY=xxx
|
|
```
|
|
|
|
## 自定义实现
|
