Rewriting ScenarioDesigner method

[ShubhamShekhar1996]

In my old citrus version code I have below method:-

@Scenario("Example")
@RequestMapping(value = "/sim/example", method = RequestMethod.GET)
public class GetCircuit extends AbstractSimulatorScenario {

@Override
public void run(ScenarioDesigner scenario) {

    scenario.http().receive().get();
    scenario.http().send().response(HttpStatus.OK).header("ContentType", "application/json")
            .payload(new ClassPathResource("datamanager/example.json"));

}

}

In newer version how can I write the same code as ScenarioDesigner class no longer exist?
