sending parameters as JSON in POST body using spray - json

Question

Ok this is really bugging me.I have implemented a REST api using spray and scala,akka. I have successfully implemented spray get, post routes to query mysql database and give the json output.I am able to send the parameters within the post body but however I am not able to send the same as JSON. Its looks very simple but its just not working.I am getting error - empty reply from server. Please Please help.
Here is my sample curl command:
curl -H "Content-Type: application/json" -X POST -d '{ "name": "Jane", "favNumber" : 42 }' http://localhost:8080/jsonTesting
I am trying this small sample code to see if it is possible to unmarshall json parameters and get the required output. If it works then I am implementing the same in my actual code.
import spray.json.DefaultJsonProtocol
import spray.json._
import spray.httpx.SprayJsonSupport
object MyJsonProtocol extends DefaultJsonProtocol with SprayJsonSupport {
implicit val Format = jsonFormat2(Person)
case class Person(name:String, favNumber:Int)
//Spray main class
import akka.actor.ActorSystem
import spray.routing.SimpleRoutingApp
import spray.json.DefaultJsonProtocol
import spray.json._
import spray.http.MediaTypes._
import MyJsonProtocol._
import spray.routing._
object SprayTest extends App with SimpleRoutingApp {
implicit val system = ActorSystem()
def testRoute(route: Route): Route = {
post {
respondWithMediaType(`application/json`){
route
}
}
}
startServer(interface = "localhost", port = 8080) {
testRoute {
path("departed") {
parameter('count.as[Boolean]) {count =>
complete(if (count == true) "even ball" else "odd ball")
}
}
} ~
path("jsonTesting") {
post{
entity(as[Person]) { person =>
complete(s"Person: ${person.name} - favoritenumber:${person.favNumber}")
}
}
}
}
}
Here is the error:
Uncaught error from thread [default-akka.actor.default-dispatcher-2] shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled for ActorSystem[default]
