Create folder inside a bucket in minio using JAVA SDK

Question

The Minio JAVA SDK documentation doesn't clearly articulate how to create a folder inside a bucket.

Can somebody help me on this request ?

Thanks in Advance!

Answer 1

In the objectName parameter prefix of the putObject method, you can specify a folder name. https://docs.minio.io/docs/java-client-api-reference#putObject https://github.com/minio/minio/issues/2423#issuecomment-239408168

For example:

//objectName = folderName + "/" + fileName;
minioClient.putObject(bucketName, objectName, inputStream, contentType);

Answer 2

Create the bucket if its not present. To add folder within it add it to the name of file. Eg. File name: "sample.txt", Bucket Name: "main", SubFolder: "resrc" filePath: file which you want to upload

minioClient.putObject("main", "resrc" + "/" + "sample.txt", filePath);

Answer 3

Create or check for exist.

// Create object ends with '/' (also called as folder or directory).
minioClient.putObject(
PutObjectArgs.builder().bucket("my-bucketname").object("path/to/").stream(
new ByteArrayInputStream(new byte[] {}), 0, -1).build());
