下面是可以放在application.conf中的两个执行上下文配置示例：

background-scheduled-tasks-dispatcher {                                                
  type = Dispatcher                                                                    
  executor = "fork-join-executor"    
  fork-join-executor {
    parallelism-min = 2
    parallelism-factor = 2.0
    parallelism-max = 10
  }
  throughput = 1
}

blocking-io-ec {
  type = Dispatcher
  executor = "thread-pool-executor"
  thread-pool-executor {
    fixed-pool-size = 50
  }
  throughput = 1
}

下面是一个如何在你的应用程序中访问其中之一的例子：

val ec :ExecutionContext = actorSystem.dispatchers.lookup("blocking-io-ec")

您可以为该行添加前缀implicit val ec，也可以显式使用它

someFuture.map(myFunc)(ec)
