Stop consume message for Stream listener

Question

I am looking for a way to stop consume messages with stream listener.

@StreamListener(MBinding.M_INPUT)
    public void consumeMessage(Message<MerchantEvent> message) {
    //handle when receive message
 }

cloud:
        stream:
            bindings:
                MInput:
                    destination: topicName
                    group: groupName

I have googled it but right now still have no idea how to stop consuming. Is there anyone who know it?

You can do it using the actuator (see Binding Visualization and Control). Or you can invoke the endpoint programmatically.

@SpringBootApplication
@EnableBinding(Sink.class)
public class So58795176Application {

    public static void main(String[] args) {
        SpringApplication.run(So58795176Application.class, args);
    }

    @StreamListener(Sink.INPUT)
    public void listen(String in) {
        System.out.println();
    }

    @Autowired
    BindingsEndpoint endpoint;

    @Bean
    public ApplicationRunner runner() {
        return args -> {
            System.in.read();
            endpoint.changeState("input", State.STOPPED);
            System.in.read();
            endpoint.changeState("input", State.STARTED);
        };
    }

}
