Some ideas for Lift JSON intergation in Play! framework

gistfile1.scala

object Foo0 extends Controller{
	
	def bar = Json(createAnObject) // Default serialization is used.

	def bar2 = Json(createAnObject, createAnotherFormats) // default formats are overriden

}

object Foo1 extends Controller{

	// The first idea of specifying formats for a Controller is overriding a default method.
	override protected def liftJsonFormats = createFormats // specify default formats
	
	// I can copy&paste bar and bar2 methods there, but you probably know them.

}

object Foo2 extends Controller(
	liftJsonFormats = createFormats()	// Another idea of specifying formats is passing a constructor parameter. Which one is better?
){
	
	// I can copy&paste bar and bar2 methods there, but you probably know them.
	
}

object Foo3 extends Controller(
	jsonAdapter = new LiftJsonAdapter(createFormats())	// Maybe we should not rely on a specific library.
){
	
	def bar = Json(createAnObject)

	def bar2 = Json(createAnObject, new LiftJsonAdapter(createAnotherFormats)) // default formats are overriden
	
}
