如何通过websocket broker在spring boot中按提交顺序发送消息？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/topic");
        registry.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/websocket").withSockJS();
    }
}

@Component
public class MyWebSocketHandler implements WebSocketHandler {

    private final List<WebSocketSession> sessions = new CopyOnWriteArrayList<>();

    @Override
    public void afterConnectionEstablished(WebSocketSession session) throws Exception {
        sessions.add(session);
    }

    @Override
    public void handleMessage(WebSocketSession session, WebSocketMessage<?> message) throws Exception {
        // 处理接收到的消息
        String payload = message.getPayload().toString();
        // 发送消息给所有连接的客户端
        for (WebSocketSession s : sessions) {
            s.sendMessage(new TextMessage(payload));
        }
    }

    @Override
    public void handleTransportError(WebSocketSession session, Throwable exception) throws Exception {
        // 处理传输错误
    }

    @Override
    public void afterConnectionClosed(WebSocketSession session, CloseStatus closeStatus) throws Exception {
        sessions.remove(session);
    }

    @Override
    public boolean supportsPartialMessages() {
        return false;
    }
}

@Autowired
private MyWebSocketHandler webSocketHandler;

public void sendMessage(String message) {
    // 发送消息给所有连接的客户端
    for (WebSocketSession session : webSocketHandler.getSessions()) {
        session.sendMessage(new TextMessage(message));
    }
}
