ConfigFactory.parseString(source.mkString).getConfig("conf") 它没有找到“conf”,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"
    }

  }
    }

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

在com.typesafe.config.impl.SimpleConfig.findKey(SimpleConfig。java:124) 在com.typesafe.config.impl.SimpleConfig.find(SimpleConfig。java:159) 在com.typesafe.config.impl.SimpleConfig.getObject(SimpleConfig。java:218) 在com.typesafe.config.impl.SimpleConfig.getConfig(SimpleConfig。java:224) 在com.typesafe.config.impl.SimpleConfig.getConfig(SimpleConfig。java:33) 位于com.dsm.utils.Test.main(Test.scala)

实际上,您成功地读取了配置。

你的问题是因为 BufferedSource rawConfig 你得到一个空字符串。我通过将配置字符串提取到一个变量中,然后使用它来解决这个问题。

val config = source.mkString
println(s"config is: $config")
val rawConfig: Config = ConfigFactory.parseString(config)
val rootConfig = rawConfig.getConfig("conf")
println(s"rootConfig is: $rootConfig")

rootConfig is: Config(SimpleConfigObject({"OL":{"filename":"receipts_delta_GBR_14_10_2017.csv","sftp_conf":{"delimiter":"|","directory":"/home/ubuntu/data","filetype":"csv","hostname":"endpoint","pem":"pemfile","port":"22","username":"ubuntu"}},"source_data_list":["OL","SB","1CP"]}))
