Get Message From Kafka, send to Rsocket and Receive it from React client

问题

I am trying to send data from kafka using Spring cloud stream to Rsocket and then represent data on React

Here is my configuration.

@Configuration
public class RsocketConsumerConfiguration {
    
    @Bean
    public Sinks.Many<Data> sender(){
        return Sinks.many().multicast().directBestEffort();
    }
    

}

@Controller public class ServerController {

@Autowired
private Sinks.Many<Data> integer;

@MessageMapping("integer")
public Flux<Data> integer() {
    return  integer.asFlux();
}

@EnableBinding(IClientProcessor.class)
public class Listener {

    @Autowired
    private Sinks.Many<Data> integer;

    @StreamListener(IClientProcessor.INTEGER)
    public void integer(Data val) {
        System.out.println(val);
        integer.tryEmitNext(val);
    }

}

   let  client = new RSocketClient({
    transport: new RSocketWebSocketClient(
        {
            url: 'ws://localhost:7000/ws',
            wsCreator: (url) => new WebSocket(url),
            debug: true,
        },
        BufferEncoders,
    ),
    setup: {
        dataMimeType: "application/json",
        metadataMimeType: MESSAGE_RSOCKET_COMPOSITE_METADATA.string,
        keepAlive: 5000,
        lifetime: 60000,
    },
});

  client
            .then(rsocket => {
                console.log("Connected to rsocket");
                rsocket.requestStream({
                    metadata: Buffer.from(encodeCompositeMetadata([
                        [MESSAGE_RSOCKET_ROUTING, encodeRoute("integer")],
                    ])),
                 
                })
                    .subscribe({
                        onSubscribe: s => {
                            s.request(2147483647)
                        },
                        onNext: (p) => {
                            let newData = {
                                time: new Date(JSON.parse(p.data).time).getUTCSeconds(),
                                integer: JSON.parse(p.data).integer
                            }
                           newData.integer >100?setInteger(currentData => [newData, ...currentData]):setInt(currentData => [newData, ...currentData])
                           console.log(newData)
                        },
                        onError: (e) => console.error(e),
                        onComplete: () => console.log("Done")
                    });

spring.cloud.stream.bindings.integer.destination=integer Not able to see it in react app. Please advise. What I am doing wrong?
