使用S3 Java SDK与S3兼容存储(minio)通信

Question

我正在尝试使用aws-sdk-java AwsS3client与minio存储进行通信.从CLI我可以做到:

aws --profile=minioplay  --endpoint-url https://play.minio.io:9000 s3 cp logback.xml s3://miniohstest-jixusroqeb --debug

因此使用非默认配置文件和自定义端点.不知道如何从java sdk执行此操作(我能够吗？).我粗略地将上面的awscli命令翻译成这个scala片段:

val cred = ...
val endpoint = "https://play.minio.io:9000"
val client = AmazonS3ClientBuilder
      .standard()
      .withCredentials(cred)
      .withEndpointConfiguration(
        new EndpointConfiguration(
          endpoint,
          AwsHostNameUtils.parseRegion(endpoint, AmazonS3Client.S3_SERVICE_NAME)
        )
      )
      .build()

使用上面的客户端我只能做出非常简单的请求,例如:

client.listBuckets().asScala.foreach(println(_))

哪个有效.但是当我尝试做一些先进的事情时,例如:

val listRequest = new ListObjectsRequest()
      .withBucketName("miniohstest-jixusroqeb")
      //.withPrefix(r.getURI.getPath)
      //.withDelimiter(delimiter)

val res = client.listObjects(listRequest)
res.getObjectSummaries.forEach(x => println(x.getKey))

它抛出以下异常:

Exception in thread "main" com.amazonaws.SdkClientException: Unable to execute HTTP request: miniohstest-jixusroqeb.play.minio.io
    at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleRetryableException(AmazonHttpClient.java:1114)
    at com.amazonaws.http.AmazonHttpClient$RequestExecutor.executeHelper(AmazonHttpClient.java:1064)
    at com.amazonaws.http.AmazonHttpClient$RequestExecutor.doExecute(AmazonHttpClient.java:743)

我究竟做错了什么？

我通过设置解决了这个withPathStyleAccessEnabled(true).
