I'm attempting to test out Akka with Play 2.5 and I'm running into a compile error I can't seem to get around.
I'm following this page from the Play docs: https://playframework.com/documentation/2.5.x/ScalaAkka
Here is the full code:
package controllers
import javax.inject.{Inject, Singleton}
import akka.actor.ActorSystem
import controllers.HelloActor.SayHello
import play.api.mvc._
import play.api.libs.concurrent.Execution.Implicits.defaultContext
import scala.concurrent.duration._
import akka.pattern.ask
@Singleton
class Application @Inject()(system: ActorSystem) extends Controller {
implicit val timeout = 5.seconds
val helloActor = system.actorOf(HelloActor.props, "hello-actor")
def sayHello(name: String) = Action.async {
(helloActor ? SayHello(name)).mapTo[String].map { message =>
Ok(message)
}
}
}
import akka.actor._
object HelloActor {
def props = Props[HelloActor]
case class SayHello(name: String)
}
class HelloActor extends Actor {
import HelloActor._
def receive = {
case SayHello(name: String) =>
sender() ! "Hello, " + name
}
}
My route looks like:
GET /:name controllers.Application.sayHello(name: String)
And, finally, my build.sbt:
name := "AkkaTest"
version := "1.0"
lazy val `akkatest` = (project in file(".")).enablePlugins(PlayScala)
scalaVersion := "2.11.7"
libraryDependencies ++= Seq( jdbc , cache , ws , specs2 % Test )
unmanagedResourceDirectories in Test <+= baseDirectory ( _ /"target/web/public/test" )
resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases"
routesGenerator := InjectedRoutesGenerator
When I attempt to run this, I get the following compilation error:
could not find implicit value for parameter timeout: akka.util.Timeout
I've tried moving around the timeout to no avail. Does anyone have an idea what might cause this compilation error?
