将隐式传递给playframework JSON读取

Question

I would like to know whats the best way to pass an implicit to a Playframework Json Reader/Writer

http://www.playframework.com/documentation/api/2.0/scala/play/api/libs/json/Reads.html

In other words I would like to be able to do something like :

def reads(json: JsValue)(implicit configuration: TenantConfiguration): JsResult[User]

But I can't do it this way since the Reads trait doesn't match

You can't change Reads[T], it's clear. I would simply create my own reads function such as?

def customReads[T](json:JsValue)(implicit reads: Reads[T], configuration: TenantConfiguration): JsResult[T] = ...
