Question

我目前正在从游戏2.4迁移到2.5。

我正在尝试在测试中运行许多NettyServer，但我只能访问最后创建的

import akka.actor.ActorSystem
import akka.stream.ActorMaterializer
import org.scalatest.{FlatSpec, Matchers}
import org.scalatest.concurrent.ScalaFutures
import org.scalatest.time.{Seconds, Span}
import play.api.libs.ws.ahc.AhcWSClient
import play.api.mvc.{Action, Results}
import play.core.server.{NettyServer, ServerConfig}
import play.api.routing.sird._

class NettyServerTest extends FlatSpec with Matchers with ScalaFutures {

  override implicit val patienceConfig = PatienceConfig(Span(5, Seconds))

  implicit val system = ActorSystem()
  implicit val materializer = ActorMaterializer()

  private val wsClient = AhcWSClient()

  it should "print 'Hello I am the secondServer' then 'Hello I am the firstServer'" in {

    val firstServer = createServer("firstServer")
    val secondServer = createServer("secondServer")
    try {
      println(wsClient.url(s"http://localhost:${secondServer.httpPort.get}/hello").get().futureValue.body)
      println(wsClient.url(s"http://localhost:${firstServer.httpPort.get}/hello").get().futureValue.body)
    } finally {
      firstServer.stop()
      secondServer.stop()
    }
  }

  def createServer(server: String): NettyServer = {
    NettyServer.fromRouter(ServerConfig(port = Some(0))) {
      case GET(p"/hello") => Action {
        Results.Ok(s"Hello I am the $server")
      }
    }
  }
}

当我运行测试时，它只打印'Hello我是第二个服务器'，然后我收到错误：

The future returned an exception of type: java.net.ConnectException, with message: Connection refused: no further information: localhost/0:0:0:0:0:0:0:1:58096.

...

我有以下依赖项：

"com.typesafe.play" %% "play-netty-server" % "2.5.4"
"com.typesafe.play" %% "play-ws" % "2.5.4"

此测试正在使用play 2.4

最后，我成功通过覆盖netty服务器使用的actorSystem来使其工作：

import akka.actor.ActorSystem
import akka.stream.ActorMaterializer
import org.scalatest.concurrent.ScalaFutures
import org.scalatest.time.{Seconds, Span}
import org.scalatest.{FlatSpec, Matchers}
import play.api.BuiltInComponents
import play.api.libs.ws.ahc.AhcWSClient
import play.api.mvc.{Action, Results}
import play.api.routing.Router
import play.api.routing.sird._
import play.core.server.{NettyServer, NettyServerComponents, ServerConfig}

class NettyServerTest extends FlatSpec with Matchers with ScalaFutures {

  override implicit val patienceConfig = PatienceConfig(Span(5, Seconds))

  implicit val system = ActorSystem()
  implicit val materializer = ActorMaterializer()

  private val wsClient = AhcWSClient()

  it should "print 'Hello I am the secondServer' then 'Hello I am the firstServer'" in {

    val firstServer = createServer("firstServer")
    val secondServer = createServer("secondServer")
    try {
      wsClient.url(s"http://localhost:${firstServer.httpPort.get}/hello").get().futureValue.body shouldBe "Hello I am the firstServer"
      wsClient.url(s"http://localhost:${secondServer.httpPort.get}/hello").get().futureValue.body shouldBe "Hello I am the secondServer"
    } finally {
      firstServer.stop()
      secondServer.stop()
    }
  }

  def createServer(serverName: String): NettyServer = {
    new NettyServerComponents with BuiltInComponents {
      lazy val router = Router.from {
        case GET(p"/hello") => Action {
          Results.Ok(s"Hello I am the $serverName")
        }
      }
      override lazy val serverConfig = ServerConfig(port = Some(0))
      override lazy val actorSystem: ActorSystem = ActorSystem()
    }.server
  }
}

使用play 2.5运行多个NettyServer时连接被拒绝
