我正在尝试读取存储在s3 bucket中的application.conf。我使用bufferedsource从s3中读取，但是当我尝试使用 ConfigFactory.parseString(source.mkString).getConfig("conf") 它没有找到“conf”，它就在那里。下面是我的源代码：

import com.amazonaws.auth.DefaultAWSCredentialsProviderChain
import com.amazonaws.services.s3.model.S3Object
import com.amazonaws.services.s3.{AmazonS3Client, AmazonS3ClientBuilder, AmazonS3URI}
import scala.collection.JavaConversions._

import scala.io.{BufferedSource, Source}

object Test {
  def main(args: Array[String]): Unit = {

    import com.amazonaws.auth.BasicAWSCredentials
    val credentials = new BasicAWSCredentials("key", "secertkey")
  //  val credentialsProvider = new DefaultAWSCredentialsProviderChain()
    val s3Client = new AmazonS3Client(credentials)
    val uri: AmazonS3URI = new AmazonS3URI("s3://test-buck/conf/application.conf")
    val s3Object: S3Object = s3Client.getObject(uri.getBucket, uri.getKey)

    val source: BufferedSource = Source.fromInputStream(s3Object.getObjectContent)
    try {
      println(source.mkString)
      import com.typesafe.config.{Config, ConfigFactory}
      val rawConfig: Config = ConfigFactory.parseString(source.mkString)
      val rootConfig = rawConfig.getConfig("conf")

      println(rootConfig)
//      println(rotConfig)
    } finally {
      source.close()
    }

  }

}
我的应用程序配置如下所示

conf {

       source_data_list = ["OL", "SB","1CP"]
//some other value

 OL {
    filename = "receipts_delta_GBR_14_10_2017.csv"
    sftp_conf {
      hostname = "endpoint"
      port = "22"
      username = "ubuntu"
      pem = "pemfile"
      filetype = "csv"
      delimiter = "|"
      directory = "/home/ubuntu/data"
    }

  }
    }

我不知道我做错了什么。如果我放在资源上并尝试加载相同的应用程序配置 ConfigFactory.load("application.conf").getConfig("conf") 它按预期工作。任何线索都会有帮助。
我有个例外
