当与Play 2.2.1一起使用时，带有Akka 2.3.0的Akka Persistence Cassandra引发致命的EOFException [英] Akka Persistence Cassandra with Akka 2.3.0 throwing fatal EOFException when used with Play 2.2.1

问题描述

您知道为什么在将Akka添加到我的库依赖项并执行test任务后会出现以下错误吗?

Any idea why I am getting the following error after adding Akka to my library dependencies and executing the test task?

Uncaught error from thread [reactivemongo-akka.actor.default-dispatcher-4] shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled for ActorSystem[reactivemongo]

当我执行run任务时:

我相关的build.sbt设置

scalaVersion := "2.10.3"

// Dependencies

resolvers ++= Seq(
  "Sonatype Releases" at "http://oss.sonatype.org/content/repositories/releases",
  "Krasser's Bintray" at "http://dl.bintray.com/krasserm/maven"
)

libraryDependencies ++= Seq(
  // akka
  "com.typesafe.akka" %% "akka-actor" % "2.3.0",
  "com.typesafe.akka" %% "akka-persistence-experimental" % "2.3.0",
  "com.github.krasserm" % "akka-persistence-cassandra_2.10" % "0.2",
  // dependency injection

  "org.scalacheck" %% "scalacheck" % "1.11.3" % "test"
)

// App settings

play.Project.playScalaSettings

还有我的project/plugin.sbt

resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.1")

这是在我添加了具有以下库的akka​​-persistence插件之后开始的:

This started after I added the akka-persistence plugin with the following libs:

"com.typesafe.akka" %% "akka-actor" % "2.3.0",
"com.typesafe.akka" %% "akka-persistence-experimental" % "2.3.0",
"com.github.krasserm" % "akka-persistence-cassandra_2.10" % "0.2"

我安装了Cassandra，并在本地运行它.

I installed Cassandra and I am running it locally while doing this.

即使我注释掉其中任何一行并运行sbt clean，sbt update和sbt test，我仍然会看到此错误.只有当我全部对它们发表评论后，我才能运行和测试我的应用.

Even if I comment any one of these lines out and run sbt clean, sbt update, and sbt test I still see this error. Only when I comment them all out am I able to run and test my app.

我唯一的猜测是持久性库中的Akka版本与Play2不兼容.

My only guess is that the version of Akka in the persistence library and Play2 are incompatible.

听起来不错吗?

推荐答案

播放2.2.x使用Akka2.2.x.您需要等待与Akka 2.3兼容的Play 2.3.

Play 2.2.x uses Akka 2.2.x. You'll need to wait for Play 2.3 which will be compatible with Akka 2.3.
