@EnableWebSocketMessageBroker
@Service
public class QuotesSocket {

    @Value("${app.quotes.socket.url}")
    private String url;
    private Logger logger = LogManager.getLogger(QuotesStompSessionHandler.class);

    WebSocketStompClient webSocketStompClient;

    @PostConstruct
    public void connect() {
        WebSocketClient client = new StandardWebSocketClient();
        webSocketStompClient = new WebSocketStompClient(client);
        webSocketStompClient.setMessageConverter(new MappingJackson2MessageConverter());
        StompSessionHandler sessionHandler = new QuotesStompSessionHandler();
        webSocketStompClient.connect(url, sessionHandler);

        new Scanner(System.in).nextLine();
    }

@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {

    }

}

WebSocketClient is in spring-webflux. I guess you forgot to include a dependency? Is this relevant to the guide? I'm guessing not, but if you think it is just squawk and we can dig into it more.
