Question

我面临以下代码的未知主机异常。我不确定代码有什么问题。

@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;
     }
}

我能够看到兔子在主机上运行我可以在此处http://hostname:15672/看到管理控制台电话网正在工作 Telnet主机名15672
超时3 bash -c'cat / dev / tcp / hostname / 15672';回显$？

这是日志：

org.springframework.amqp.AmqpIOException: java.net.UnknownHostException:host-name

@PostConstruct
    public void getAIMCredentails() {
        tempApiCallMock();
    }


    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";
    }

感谢纠正我，我将端口更改为5672，但仍然是同一问题。和我的telnet主机5672可以工作

Answer 1

mvn

是错误的。 connectionFactory.setAddresses(Arrays.toString(rabbitMqConfig.getSubscriberHosts()));期望使用逗号分隔的字符串，而不是数组的字符串表示形式。

查看其JavaDocs：

setAddresses()
