Answer 1

There are many ways. I use this one.

Edit: This is relevant for Play versions which are <= 2.4:

Play.maybeApplication.map(_.injector.instanceOf[MyProdClass]).getOrElse(new MyDevClass)

or

Play.current.injector.instanceOf[MyClass]

For versions which are >= 2.5:

import play.api.inject.Injector
import javax.inject.Inject

class MyService @Inject() (injector: Injector) ={
    val myClassInstance = injector.instanceOf[MyClass]
    //do stuff
}
