Akka集群配置

Question

我得到了这个错误：

[ERROR] [05/04/2018 11:21:26.747] [default-akka.actor.default-dispatcher-19]

当尝试创建(仅限本地) akka集群时。我在application.conf中将我的配置精简为几行：

akka {
    actor {
        provider = "akka.cluster.ClusterActorRefProvider"
    }
    cluster {
        seed-nodes = ["akka.tcp://ClusterSystem@127.0.0.1:2552"]
    }
}

并在启动ActorSystem时出现错误：

fun main(args: Array<String>) {
    ActorSystem.create()
}

我使用的是akka版本2.5.12和scala版本2.12。

Answer 1

所以我在我的maven pom中加入了com.twitter chill-akka版本的0.9.2。这包括com.typesage config版本的1.2.1。com.typesafe.akka akka-actor-typed version 2.5.12需要的版本是1.3.2

所以现在我的maven include看起来像这样：

<dependency>
    <groupId>com.twitter</groupId>
    <artifactId>chill-akka_${scala.version}</artifactId>
    <version>0.9.2</version>
    <exclusions>
        <exclusion>
            <groupId>com.typesafe</groupId>
            <artifactId>config</artifactId>
        </exclusion>
    </exclusions>
</dependency>
