Rabbit MQ org.springframework.amqp.AmqpIOException: java.net.UnknownHostException - spring-boot

Question

I am facing unknown-host exception for below code. I am not sure what is wrong with code.
#Component
#Configuration
public class RabbitListenerContainerFactory {
static final Logger logger = LoggerFactory.getLogger(RabbitListenerContainerFactory.class);
#Autowired
RabbitMqConfig rabbitMqConfig;
#Autowired
EPPQ2Subscriber receiver;
#Autowired
EPPQ2ChanelAwareSubscriber receiverChanel;
public RabbitListenerContainerFactory(ConfigurableApplicationContext ctx) {
printContainerStartMsg();
}
private void printContainerStartMsg() {
logger.info("----------- Scrubber Container Starts --------------");
}
#Bean
public SimpleMessageListenerContainer queueListenerContainer(ConnectionFactory connectionFactory,
MessageListenerAdapter listenerAdapter) {
SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(connectionFactory);
container.setQueueNames(rabbitMqConfig.getSubscriberQueueName());
// container.setQueueNames("SampleQueue"); /*This just for testing.. !*/
container.setMessageListener(listenerAdapter);
container.setAcknowledgeMode(AcknowledgeMode.MANUAL);
container.setDeclarationRetries(5);// This is default to 3, We can twick this and move this to prop
container.setPrefetchCount(100); //Tell the broker how many messages to send to each consumer in a single request.
return container;
}
#Bean
MessageListenerAdapter listenerAdapter(EPPQ2Subscriber receiver) {
return new MessageListenerAdapter(receiver, "receiveMessage");
}
/*#Bean
MessageListenerAdapter listenerAdapterWithChanel(EPPQ2ChanelAwareSubscriber receiverChanel) {
return new MessageListenerAdapter(receiverChanel);
}*/
#Bean
ConnectionFactory connectionFactory () {
final CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
connectionFactory.setAddresses(Arrays.toString(rabbitMqConfig.getSubscriberHosts()));
//connectionFactory.setHost(Arrays.toString(rabbitMqConfig.getSubscriberHosts()));
connectionFactory.setVirtualHost("hydra.services");
connectionFactory.setPort(rabbitMqConfig.getSubscriberPort());
connectionFactory.setUsername(rabbitMqConfig.getSubscriberUsername());
connectionFactory.setPassword(rabbitMqConfig.getSubscriberPassword());
return connectionFactory;
}
}
I am able to see rabbit running on the host
I can see admin console here http://hostname:15672/
Tel net is working
Telnet hostname 15672
timeout 3 bash -c 'cat < /dev/null > /dev/tcp/hostname/15672 '; echo $?
Here is log :
org.springframework.amqp.AmqpIOException: java.net.UnknownHostException:host-name

private void tempApiCallMock() {
String [] host = {"10.30.190.25"};
this.subscriberHosts = host;
this.subscriberPort = 5672;
this.subscriberQueueName = "hydra.Syphon.q1";
this.subscriberUsername = "dftp_subscriber";
this.subscriberPassword = "dftp_subscriber";
this.publisherHosts = host;
this.publisherPort = 5672;
this.publisherUsername = "dftp_publisher";
this.publisherPassword = "dftp_publisher";
}
Thanks for Correcting me I changed the port to 5672 But still the same issue.
and my telnet host 5672 works

Answer 1

The connectionFactory.setAddresses(Arrays.toString(rabbitMqConfig.getSubscriberHosts()));
is wrong. The setAddresses() expects a comma-separate string, not a string representation of the array.
See its JavaDocs:
/**
* Set addresses for clustering.
* This property overrides the host+port properties if not empty.
* #param addresses list of addresses with form "host[:port],..."
*/
public void setAddresses(String addresses) {
