abstract class LagomApplicationLoader extends ApplicationLoader with ServiceDiscovery

A Play application loader for Lagom.

Scala Lagom applications should provide a subclass of this to create their application, and configure it in their application.conf file using:

play.application.loader = com.example.MyApplicationLoader

This class provides an abstraction over Play's application loader that provides Lagom specific functionality.

    Load a Lagom application for production.

    This should mix in a production service locator implementation, and anything else specific to production, to an application provided subclass of LagomApplication. It will be invoked to load the application in production.

    The Lagom application context.

    returns

    A Lagom application.

    Implementation of Play's load method.

    Implementation of Play's load method.

    Since Lagom applications need to use a different wiring in dev mode, using the dev mode service locator and registry, to what they use in prod, this separates the two possibilities out, invoking the load() method for prod, and the loadDevMode() method for development.

    It also wraps the Play specific types in Lagom types.

    Load a Lagom application for development.

    This should mix in LagomDevModeComponents with an application provided subclass of LagomApplication, such that the service locator used will be the dev mode service locator, and so that services get registered with the dev mode service registry.

    context

    The Lagom application context.

    returns

    A lagom application.
