I\'m looking at the scaly code example from play-mailer: https://github.com/playframework/play-mailer

It goes basically like this:

class MyComponent @         


        

Answer 1

this is not a scala Issues, but a DI one. You should read some guice documentation.

In Play 2.4.x, you need to use dependency injection (https://www.playframework.com/documentation/2.4.x/ScalaDependencyInjection) to achieve your goal.

Your AnObject should be:

@Singleton class AnObject @Inject()(mailer:MyComponent){
 def sendEmail = mailer.doStuff
}
