Question

我的Spring启动应用程序抛出连接超时错误，它永远无法连接。我看到的另一个有趣的问题是，它永远不会获取spring app properties中定义的连接超时属性。

这是我的java配置，

    @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);
    }


}

我的spring应用程序属性看起来像，

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已启动并在端口15672上运行127.0.0.1，但应用程序永远无法连接。

Answer 1

默认情况下，AMQP端口为5672.端口15672显示Web UI（管理控制台）。如果您使用的是默认设置，请调整

spring.rabbitmq.port = 5672
