Compile time dependency injection with filters?

[Yevgeniy Brikman]

Is there any way to use the Scala Compile Time Dependency Injection with Filters? For example, I have a Filter class that needs a Cache class injected. I'm using compile time injection, so I can't just use an @Inject annotation. However, it seems that Play loads the Filters via reflection from one configuration parameter (play.http.filters) and the rest of the application through a different configuration parameter (play.application.loader) and I can't find a way to make the two worlds play together nicely.

Thanks,

Jim

Answering my own question: it turns out that the BuiltInComponentsFromContext include a variable called httpFilters that you can override to provide your own filters. Example:

class MyLoader extends ApplicationLoader {

  override def load(context: Context): Application = {

    new MyComponents(context).application

  }

}

class MyComponents(context: Context) extends BuiltInComponentsFromContext(context) {

  val myFilter = new CustomFilter()

  override lazy val httpFilters = Seq(myFilter)

}

Just had the exact same question - would be cool to add this to the documentation.

Hi Yevgeniy Brikman,

Did you find possibility to connect play.application.loader with play.http.filters in one project?
