PCF上RabbitMQ的春季AMQP过时消费者

标签： rabbitmq spring-amqp spring-cloud-connectors

我们的团队在使用Cloud Foundry连接器的Spring AMQP上遇到了一些问题。每当网络上出现某些不稳定情况时，连接都会失败，然后AMQP似乎会尝试自动恢复，无法自动恢复，然后创建新的使用者。

问题在于，RabbitMQ似乎并没有取消旧消费者的注册……因此，我们最终只有40个消费者，而不是通常的一个消费者。而且，我认为，由于无效使用者数量众多，旧使用者会收到一些消息，但不会运行我们的代码。因此，在应用程序重新启动并清除使用者列表之前，我们会有很多未确认的消息。

我不确定这是我们的错误配置还是错误。有什么想法吗？

下面的其他信息。

我们使用@RabbitListener注释注册我们的消费者

    @RabbitListener(id = CONSUMER_ID, queues = "${CommonInternalEndPoint}", containerFactory = "rabbitLocalContainerFactory")
    protected void process(Object messageObject) {

当我们确实连接到多个Rabbit mq实例时，我们需要手动声明连接工厂。我们的连接工厂来自Cloud Foundry连接器：

@Configuration
@Profile("cloud")
public class RabbitCloudConfiguration {

    @Bean
    public Cloud cloud(){
        return new CloudFactory().getCloud();
    }

    @Bean
    @Primary
    public ConnectionFactory connectionFactory(){
        return cloud().getSingletonServiceConnector(ConnectionFactory.class, null);
    }

    @Bean("rabbitLocalContainerFactory")
    public SimpleRabbitListenerContainerFactory rabbitLocalContainerFactory(){
        SimpleRabbitListenerContainerFactory containerFactory = new SimpleRabbitListenerContainerFactory();
        containerFactory.setConnectionFactory(connectionFactory());
        containerFactory.setAutoStartup(true);
        return containerFactory;
    }
}

答案 0 :(得分：0)

  

我们正在使用Spring Boot 1.5.9，Framework 4.3.6，AMQP 1.7.4，RabbitMQ AMQP Client 4.0.3

从2.0版开始，Spring AMQP在目标RabbitMQ automaticRecoveryEnabled：https://docs.spring.io/spring-amqp/docs/2.1.4.RELEASE/reference/#auto-recovery

上禁用ConnectionFactory

由于您使用的版本基于Cloud Connectors提供的RabbitMQ ConnectionFactory，因此您需要明确禁用它：

@Bean
@Primary
public ConnectionFactory connectionFactory(){
    ConnectionFactory connectionFactory = cloud().getSingletonServiceConnector(ConnectionFactory.class, null);
    ((CachingConnectionFactory) connectionFactory).getRabbitConnectionFactory().setAutomaticRecoveryEnabled(false);
    return connectionFactory;
}

您的解决方案将基于Spring AMQP提供的恢复机制。
