abstract class CustomExecutionContext extends ExecutionContextExecutor
This class defines a custom execution context that delegates to an akka.actor.ActorSystem.
It is very useful for situations in which the default execution context should not be used, for example if a database or blocking I/O is being used.
To define a custom context, subclass CustomExecutionContext with the dispatcher name:
@Singleton class DatabaseExecutionContext @Inject()(system: ActorSystem) extends CustomExecutionContext(system, "database-dispatcher")
and then bind it in dependency injection:
bind[DatabaseExecutionContext].to(classOf[DatabaseExecutionContext]).asEagerSingleton()
Then have the execution context passed in as an implicit parameter:
class DatabaseService @Inject()(implicit executionContext: DatabaseExecutionContext) { ... }
