SpringBoot rabbit connection timeout issue

Question

My spring boot application throws connection timeout error, and it is never able to connect. The other interesting problem I see is, it is never picking up the connection timeout property defined in spring app properties.

Here is my java config,

    @Configuration
@EnableRabbit
public class RabbitConfig {

    private final String exchange;
    private final String queueName;


    public RabbitConfig(
            @Value("${exchange.name}") String exchange,
            @Value("${queue.name}") String queue) {

        this.exchange= exchange;
        this.queueName=queue;
}

@Bean
Queue queue() {
    return new Queue(queueName, true);
}

@Bean
DirectExchange exchange() {
    return new DirectExchange(queueName);
}

@Bean
Binding binding(Queue queue, DirectExchange exchange) {
    return BindingBuilder.bind(queue).to(exchange).with(queueName);
}

@Bean
SimpleMessageListenerContainer container(RabbitAdmin admin,CachingConnectionFactory connectionFactory) {
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    connectionFactory.setCloseTimeout(10000);
    container.setQueueNames(queueName);
    container.setConnectionFactory(connectionFactory);
    //container.setMessageListener(listenerAdapter);
    return container;
}

//    @Bean
//    MessageListenerAdapter listenerAdapter(Receiver receiver) {
//        return new MessageListenerAdapter(receiver, "receiveMessage");
//    }

    @Bean
    public RabbitAdmin admin(ConnectionFactory connectionFactory) {
        return new RabbitAdmin(connectionFactory);
    }


}

And my spring application properties look like,

spring.rabbitmq.host = 127.0.0.1
spring.rabbitmq.port = 15672
spring.rabbitmq.username = guest
spring.rabbitmq.password = guest

exchange.name=myExchange
queue.name=myQueue

spring.rabbitmq.cache.connection.mode=CONNECTION
spring.rabbitmq.cache.channel.size=50
spring.rabbitmq.cache.channel.checkout-timeout= 10000

Rabbit is up and running on 127.0.0.1 on port 15672, but the app is never able to connect.

Answer 1

By default, the AMQP port is 5672. Port 15672 shows the web UI (admin console). If you're using the default setup, adjust

spring.rabbitmq.port = 5672
