У меня есть мой первый actor01.scala, как показано ниже:
import akka.actor.Actor
import akka.actor.ActorSystem
import akka.actor.Props
class HelloActor extends Actor{
override def receive = {
case "hello" => println("hello received")
case _ => println("other messages")
}
}
object actor01 extends App{
val system = ActorSystem("actor01")
val helloActor = system.actorOf(Props[HelloActor],name="myActor")
helloActor!"msg"
helloActor!"hello"
}
А мой pom.xml уже импортировал акку:
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<encoding>UTF-8</encoding>
<scala.version>2.11</scala.version>
<scala.compat.version>2.11</scala.compat.version>
</properties>
<dependency>
<groupId>com.typesafe.akka</groupId>
<artifactId>akka-actor_${scala.version}</artifactId>
<version>2.5.14</version>
</dependency>
Так что внутри intellij я компилирую и запускаю эту программу, я получил кучу исключений. Я хотел бы знать, если это ошибка кодирования или Maven репозиторий несоответствие?
