MinIo file system tool class in Java
1. Preparations
<!--minio pom-->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>7.1.0</version>
</dependency>
#minio相关配置
minio:
endpoint: http://127.0.0.1:9000
accessKey: minioadmin
secretKey: minioadmin
bucketName: icloud-test
#存储文件夹
folder: cloudRecording/
2. Tool class method
2.1: When uploading, you can set the contentType type purpose of the file
2.2: Set global access policy
因为默认是桶的权限是private,那么就在公网上不能正常访问了.一种方式是通过web端中手动设置.第二种方式就是代码手动设置.
如果不需要公网访问,那么取消即可.
