Я пытаюсь проверить состояние моего адаптера TCP, подключен он или нет.Для этой пружины предусмотрена команда шины управления, т. Е. @adapter_id.isConnected() для этой цели ссылка Spring Documentation -> 32.6 TCP-адаптеры .
Ниже приведен код потока, который предоставляет Id для адаптера:
IntegrationFlow flow = IntegrationFlows.from(Tcp.inboundAdapter(Tcp.nioClient(hostConnection.getIpAddress(),Integer.parseInt(hostConnection.getPort()))
.serializer(customSerializer)
.deserializer(customSerializer)
.id(hostConnection.getConnectionNumber())).clientMode(true).retryInterval(1000).errorChannel("testChannel").id(hostConnection.getConnectionNumber()+"adapter"))
.enrichHeaders(f->f.header("CustomerCode",hostConnection.getConnectionNumber()))
.channel(directChannel())
.handle(Jms.outboundAdapter(ConnectionFactory())
.destination(hostConnection.getConnectionNumber()))
.get();
theFlow = this.flowContext.registration(flow).id(hostConnection.getConnectionNumber()+"outflow").register();
Мой метод команд шины управления:
public boolean isConnectionAdapterConnected(String connectionName) {
MessageChannel controlChannel = ac.getBean("controlBus.input", MessageChannel.class);
String exp = "@"+connectionName+"adapter"+".isConnected()";
boolean status = controlChannel.send(new GenericMessage<String>(exp));
return status;
}
Я получаю следующую ошибку:
org.springframework.expression.EvaluationException: The method 'isConnected' is not supported by this command processor. If using the Control Bus, consider adding @ManagedOperation or @ManagedAttribute.

Следующая команда управления шины работает нормально:
@adapter_id.start()@adapter_id.stop()@adapter_id.retryConnection()
Но @adapter_id.isConnected вызывает вышеприведенное исключение.
Пожалуйста, помогите мне с вышеуказанной проблемой или есть какой-либо другой способ узнать, подключен ли мой адаптер или нет
