我正在 scala 中构建一个喷雾应用程序,我正在按照 here 的示例进行操作,但是当我去编译时出现此错误
Error:(38, 7) could not find implicit value for parameter system: akka.actor.ActorSystem
IO(Http) ! Http.Bind(webServer,
^
谷歌搜索让我无处可去,这是我的应用程序的代码
package au.net.hivemedia.polydeploy
import akka.actor.{Props, ActorRef, ActorSystem}
import akka.io.IO
import au.net.hivemedia.polydeploy.dono.http.WebServerActor
import spray.can.Http
/**

object App extends App {
final val VERSION = "1.0-SNAPSHOT"
final val CODENAME = "Twilight Sparkle"
private var instance: Dono = _
private var actorSystem: ActorSystem = _
private var webServer: ActorRef = _
override def main(args: Array[String]) {
println("Starting PolyDeploy Dono v" + VERSION)
println("=+ Project Version Codename: " + CODENAME)
instance = new Dono()
println("=+ Loading required items into the runtime")
instance.load()
println("=+ Loading new Actor System")
actorSystem = ActorSystem("DonoActorSystem")
println("=+ Starting web interface server")
webServer = actorSystem.actorOf(Props[WebServerActor], name = "WebServer")
IO(Http) ! Http.Bind(webServer,
interface = instance.getConfiguration().getString("web-bind-host"),
port = instance.getConfiguration().getInt("web-bind-port"))
}
}
如果需要,我可以发布更多代码片段
谢谢,

最佳答案
IO.apply
采用隐式 ActorSystem
。通过使用 actorSystem
将 implicit var actorSytem
设为隐式,或将 actorSystem
显式传递为 IO(Http)(actorSystem)
关于scala - IO(Http) 导致错误 "could not find implicit value for parameter system: akka.actor.ActorSystem",我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/26735649/
