Scala Global - 2.3.x

Defining a Global object in your project allows you to handle global settings for your application. This object must be defined in the default (empty) package and must extend GlobalSettings.

import play.api._

object Global extends GlobalSettings {

}

Tip: You can also specify a custom GlobalSettings implementation class name using the application.global configuration key.

You can override the onStart and onStop methods to be notified of the events in the application life-cycle:

import play.api._

object Global extends GlobalSettings {

  override def onStart(app: Application) {
    Logger.info("Application has started")
  }

  override def onStop(app: Application) {
    Logger.info("Application shutdown...")
  }

}

When an exception occurs in your application, the onError operation will be called. The default is to use the internal framework error page:

import play.api._
import play.api.mvc._
import play.api.mvc.Results._
import scala.concurrent.Future

object Global extends GlobalSettings {

  override def onError(request: RequestHeader, ex: Throwable) = {
    Future.successful(InternalServerError(
      views.html.errorPage(ex)
    ))
  }

}

If the framework doesn’t find an Action for a request, the onHandlerNotFound operation will be called:

import play.api._
import play.api.mvc._
import play.api.mvc.Results._
import scala.concurrent.Future

object Global extends GlobalSettings {

  override def onHandlerNotFound(request: RequestHeader) = {
    Future.successful(NotFound(
      views.html.notFoundPage(request.path)
    ))
  }

}

The onBadRequest operation will be called if a route was found, but it was not possible to bind the request parameters:

import play.api._
import play.api.mvc._
import play.api.mvc.Results._
import scala.concurrent.Future

object Global extends GlobalSettings {

  override def onBadRequest(request: RequestHeader, error: String) = {
    Future.successful(BadRequest("Bad Request: " + error))
  }

}
