Class CustomExecutionContext

  • All Implemented Interfaces:
    Executor, scala.concurrent.ExecutionContext, scala.concurrent.ExecutionContextExecutor
    Direct Known Subclasses:

    public abstract class CustomExecutionContext
    extends Object
    implements scala.concurrent.ExecutionContextExecutor
    Provides a custom execution context from an Pekko dispatcher.

    Subclass this to create your own custom execution context, using the full path to the Pekko dispatcher.

     class MyCustomExecutionContext extends CustomExecutionContext {
       // Dependency inject the actorsystem from elsewhere
       public MyCustomExecutionContext(ActorSystem actorSystem) {
         super(actorSystem, "");
    Then use your custom execution context where you have blocking operations that require processing outside of Play's main rendering thread.
