§Application Settings

A running instance of Play is built around the Application class, the starting point for most of the application state for Play. The Application is loaded through an ApplicationLoader and is configured with a disposable classloader so that changing a setting in development mode will reload the Application. Most of the Application settings are configurable, but more complex behavior can be hooked into Play by binding the various handlers to a specific instance through dependency injection.

Note: Application configuration has changed in Play 2.5.x so that dependency injection is the primary method of configuration.

Configuring the application through GlobalSettings class is still available, but is deprecated and may be removed in future versions. Please see the Removing `GlobalSettings` page for how to migrate away from GlobalSettings.
