Spring AMQP RabbitListener调整自动重新连接配置

我试图更好地了解经纪人宕机和重新启动时的RabbitListener行为。 我已经在localhost：6672上的docker容器中设置了一只兔子，并创建了一个简单的spring boot应用程序来侦听消息。还配置了application.yml指向这只兔子。

        @RabbitListener(containerFactory = "myListenerContainerFactory", 
                bindings = @QueueBinding(value = @Queue(value = "MY_QUEUE"), exchange = @Exchange(value = "MY_EXCHANGE"), key = "MY_KEY"))
        public void onMessage(final Mesg message) {
            //some handling
        }

还定义了以下容器工厂

    @Bean
    public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory(ConnectionFactory cf) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(cf);
        factory.setMessageConverter(new Jackson2JsonMessageConverter());
        factory.setDefaultRequeueRejected(false);
        factory.setConsumerTagStrategy(q -> "My App");
        return factory;
    }

当Rabbit容器运行时，我启动了spring boot应用程序，它能够自动创建交换/队列，并能够使用通过Rabbit管理控制台发布的消息。我在Spring Boot应用程序运行时强行移开了兔子容器（docker rm my_instance -f），它开始打印以下消息。

再次启动Rabbit容器后，spring boot应用程序似乎已检测到它，但是它打印了以下消息，我认为它没有建立成功的连接。查看日志，默认情况下似乎设置了3次重试，是否可以使用该配置来增加限制？

在处理此类案件方面是否有最佳实践？我的应用程序有望与不同的兔子群集连接，并且可能有1个或另一个可以继续维护，并且我需要一种方法来在兔子群集备份后自动重新连接。

1 个答案:

答案 0 :(得分：2)

 reply-text=NOT_FOUND - no queue 'MY_QUEUE' in vhost '/'

您有一个MY_QUEUE，它被声明为auto-delete，并且看起来在建立连接期间没有任何重新创建。考虑将其作为bean并让RabbitAdmin处理重新连接时的创建。
