Schedule job to run on the Wildfly server

Question

I need to create a task runner where it will call a method from time to time.

I saw an example and it was like this my implementation:

public class Agendador {
  // Scheduler
  private final ScheduledExecutorService s = Executors.newScheduledThreadPool(1);

  final Runnable beeper = new Runnable() {
    @Override
    public void run() {
      EncomendaController controller = new EncomendaController();
      controller.pesquisar();
    }
  };
  // Beeper Handler
  final ScheduledFuture<?> b = s.scheduleAtFixedRate(beeper, 0, 1, TimeUnit.MINUTES);
}

How can I make Wildfly execute the scheduling and execution of this task?

Answer 1

Example for the method funcaoAgendada() be invoked every second:

@Singleton
public class Agendador {
    @Schedule(second = "*/1", minute = "*", hour = "*", persistent = false)
    public void funcaoAgendada() {
        System.out.println("Função Agendada em execução!");
    }
}

Your scheduler may also have scope @Stateless or @Stateful depends on the need.
