This is only supported when the available Materializer is an ActorMaterializer.

Example

Scala

sourceval route = extractActorSystem { actorSystem =>
  complete(s"Actor System extracted, hash=${actorSystem.hashCode()}")
}

// tests:
Get("/") ~> route ~> check {
  responseAs[String] shouldEqual s"Actor System extracted, hash=${system.hashCode()}"
}

Java

sourceimport static akka.http.javadsl.server.Directives.extractActorSystem;

final Route route = extractActorSystem(actorSystem ->
  complete("Actor System extracted, hash=" + actorSystem.hashCode())
);

// tests:
testRoute(route).run(HttpRequest.GET("/"))
  .assertEntity("Actor System extracted, hash=" + system().hashCode());
