Play/Scala应用程序中未配置Akka调度程序的异常 [英] Akka dispatcher not configured exception in Play/Scala application

问题描述

我正在执行磁盘密集型操作，因此我想使用自己的线程池而不是默认线程池.

I am doing a disk intensive operation and I want to use my own thread-pool for it and not the default one.

我阅读了以下链接，并且遇到了完全相同的问题 Akka ::未配置，使用default-dispatcher的调度程序[％name％]

I read the following link, and I am facing the exact same problem Akka :: dispatcher [%name%] not configured, using default-dispatcher

但是我的配置文件略有不同，我已经尝试了建议，但是不起作用. 我在玩的application.conf具有以下内容

But my config file is slightly different, I have tried the suggestion but it not working. My application.conf in play has the following

 jpa-execution-context {
  thread-pool-executor {
    core-pool-size-factor = 10.0
    core-pool-size-max = 10
  }
}

然后在我的测试代码中执行以下操作，但出现异常.这是测试方法

And then in my test code I do the following, but I get an exception. Here is the test method

private def testContext():Future[Int]  = {
val system = ActorSystem.create()
val a = ActorSystem.create()
implicit val executionContext1 = system.dispatchers.lookup("jpa-execution-context")
Future{logger.error("inside my new thread pool wonderland");10}{executionContext1}

}

这里是个例外:

akka.ConfigurationException: Dispatcher [jpa-execution-context] not configured

推荐答案

我认为您忘记了配置中的一些元素:

I think you forgot a few elements in your configuration:

jpa-execution-context {
  type = Dispatcher
  executor = "thread-pool-executor"
  thread-pool-executor {
    core-pool-size-factor = 10.0
    core-pool-size-max = 10
  }
}
