Hi All,
I originally posted this question on SO and tried it myself but unable to
find what I am doing wrong? I get the following error. I followed this
documentation https://www.playframework.com/documentation/2.5.x/JavaWebSockets.
[error] /Users/hello/Documents/java/test_app/conf/routes:8: Cannot use a
method returning play.mvc.WebSocket[?0] as a Handler for requests
[error] GET /txstatus
controllers.Application.handleWebSocketConnection()
[error] /Users/hello/Documents/java/test_app/conf/routes:8: not enough
arguments for method createInvoker: (implicit hif:
play.core.routing.HandlerInvokerFactory[play.mvc.WebSocket[?0]])play.core.routing.HandlerInvoker[play.mvc.WebSocket[?0]].
[error] two errors found
[error] (compile:compile) Compilation failed
*Here is the problem Description:*
GET /status controllers.Application.handleWebSocketConnection()
Here is the relevant source code.
public WebSocket handleWebSocketConnection() {
return WebSocket.withActor(new F.Function<ActorRef, Props>() {
@Override
public Props apply(ActorRef actorRef) throws Throwable {
return UserActor.props(actorRef, "");
}
});}
here is my build.sbt
import play.routes.compiler.InjectedRoutesGeneratorimport play.sbt.PlayScala
name := "hello"
version := "1.0"
lazy val `dashboard` = (project in file(".")).enablePlugins(PlayScala)
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
jdbc ,
cache ,
ws ,
specs2 % Test,
"io.netty" % "netty-all" % "4.0.0")
unmanagedResourceDirectories in Test <+= baseDirectory ( _
/"target/web/public/test" )
resolvers ++= Seq(
"scalaz-bintray" at "https://dl.bintray.com/scalaz/releases";)
routesGenerator := InjectedRoutesGenerator
fork in run := true
I am using Play version 2.4.2 and all the source code is in java 8. I get
the following error
Cannot use a method returning play.mvc.WebSocket[?0] as a Handler for requests
any ideas?
Thanks!
