rabbitmq - Spring AMQP RabbitListener 调整自动重连配置

问题描述

我试图更好地理解RabbitListener经纪人倒闭和恢复时的行为。我已经通过 localhost:6672 在 docker 容器中设置了一只兔子，并创建了一个简单的 Spring Boot 应用程序来监听消息。还配置application.yml为指向这只兔子。

        @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，并且能够使用我通过 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除了 rabbit 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 应用程序似乎已经检测到它，但是它打印了以下消息并且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，是否有可以用来增加限制的配置？

处理此类案件是否有任何最佳实践？我的应用程序预计将与不同的兔子集群连接，并且其中一个或另一个可能会继续维护，我需要一种在兔子集群备份后立即自动重新连接的方法。

解决方案

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

您有一个MY_QUEUE声明为auto-delete并且看起来在连接建立期间没有它的娱乐。考虑将它作为一个 bean 并让它RabbitAdmin在重新连接时处理它的创建。
