Question

我有akka项目。

这是src / resources文件夹中的application-1.conf。

akka {
  loglevel="INFO"
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }
  remote {
    enabled-transports = ["akka.remote.netty.tcp"]
    netty.tcp {
     hostname = "127.0.0.1"
     port = 2552
   }
    log-sent-messages=on
    log-received-messages=on
 }
}

以下是我在文件夹src / main / scala / example7_2的软件包example7_2中的操作。

package example7_2

import akka.actor.Actor
class SimpleActor extends Actor {
  override def receive: Receive = {
    case msg => println(s"I have been created at 
    ${self.path.address.hostPort} and received message $msg")
 }

}

我有以下主要应用HelloAkkaRemoting10。

package example7_2

import akka.actor.ActorSystem
import com.typesafe.config.ConfigFactory

object HelloAkkaRemoting10 extends App {
  val actorSystem = ActorSystem("HelloAkkaRemoting1", ConfigFactory.load("application-1"))
}

当我运行应用程序时，我得到了

其他杂项详情 -

sbt version - 1.0.2 scala版本 - 2.12.3 akka版本 - 2.5.4

向我看来ConfigFactory加载错误但不确定确切的根本原因。如果我遗漏任何配置，请告诉我。

Answer 1

这似乎是sbt中的一个与Typesafe配置无关的错误，只是与Akka略有关系，我已将其归档为https://github.com/sbt/sbt/issues/3736

java.lang.ClassNotFoundException：scala.Int加载typesafe配置时出错
