问题
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.
回答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
