Getting Started

SimpleRoutingApp

spray-routing also comes with the SimpleRoutingApp trait, which you can use as a basis for your first spray endeavours. It reduces the boilerplate to a minimum and allows you to focus entirely on your route structure.

Just use this minimal example application as a starting point:

import spray.routing.SimpleRoutingApp

object Main extends App with SimpleRoutingApp {
  implicit val system = ActorSystem("my-system")

  startServer(interface = "localhost", port = 8080) {
    path("hello") {
      get {
        complete {
          <h1>Say hello to spray</h1>
        }
      }
    }
  }
}

This very concise way of bootstrapping a spray-routing application works nicely as long as you don’t have any special requirements with regard to the actor which is running your route structure. Once you need more control over it, e.g. because you want to be able to use it as the receiver (or sender) of custom messages, you’ll have to fall back to creating your service actor “manually”. The Complete Examples demonstrate how to do that.
