|
||||
##### 资源接口 |
||||
|
||||
resourcesController 资源上传 uploadFile / 下载 deleteResource / 预览 readFile |
||||
|
||||
用minio 作为资源管理 |

|
||||
```java |
||||
minio: |
||||
endpoint: http://39.106.16.162:9090 #MinIO服务所在地址 |
||||
bucketName: teaching # 存储桶名称 |
||||
accessKey: minioadmin # 访问的key |
||||
secretKey: minioadmin # 访问的秘钥 |
||||
``` |
||||
|

minioutils 工具类 |
