Play 2.5.X: the current method in the Play object is deprecated: this is a static link to the application, use DI instead

I am new to PlayFramework.

Please give me an example of how to access the configuration options from my view. I am using PlayFramework 2.5.3

Old way (@current deprecated):

@current.configuration.getString("environment.param")

New way (as far as I understand, the configuration should be introduced):

I know how to access it from the controller.

@Inject() (val messagesApi: MessagesApi, configuration: Configuration)

How to use it from my view?
