RabbitMQ频道关闭

Question

我正在使用spring-boot和RabbitMQ开发一个项目。我在RabbitMQ上有两个队列，可以监听事件。

如果我启动该过程，它会运行几个小时，但之后会记录以下异常，并且所有消息都在RabbitMQ队列中，并且没有被处理。

com.rabbitmq.client.AlreadyClosedException: channel is already closed due to clean channel shutdown; protocol method: #method<channel.close>(reply-code=200, reply-text=OK, class-id=0, method-id=0)

这些错误有时会发生在其中一个侦听器中，有时也会发生。一旦这些开始，队列处理就完全停止了。它们在多次重启服务器（Java）后开始工作

这是我的配置：

  @Bean
  public ConnectionFactory rabbitConnectionFactory() {
    CachingConnectionFactory connectionFactory =
        new CachingConnectionFactory(rabbitmqUrl);
    connectionFactory.setUsername(rabbitmqUser);
    connectionFactory.setPassword(rabbitmqPassword);
    return connectionFactory;
  }

  @Bean
  SimpleMessageListenerContainer containerQ1(ConnectionFactory connectionFactory,
                                           @Qualifier("RabbitMQQ1IndexUpdateListenerAdapter") MessageListenerAdapter listenerAdapter) {
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    container.setConnectionFactory(connectionFactory);
    container.setQueueNames(queue1);
    container.setMessageListener(listenerAdapter);
    container.setMaxConcurrentConsumers(2);
    container.setMessageConverter(jackson2Converter());
    container.setAcknowledgeMode(AcknowledgeMode.MANUAL);
    container.setPrefetchCount(30000);
    return container;
  }

  @Bean
  SimpleMessageListenerContainer containerQ2(ConnectionFactory connectionFactory,
                                           @Qualifier("RabbitMQQ2IndexUpdateListenerAdapter") MessageListenerAdapter listenerAdapter) {
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    container.setConnectionFactory(connectionFactory);
    container.setQueueNames(queue2);
    container.setMessageListener(listenerAdapter);
    container.setMaxConcurrentConsumers(2);
    container.setMessageConverter(jackson2Converter());
    container.setAcknowledgeMode(AcknowledgeMode.MANUAL);
    container.setPrefetchCount(30000);
    return container;
  }

  @Bean(name = "RabbitMQQ1IndexUpdateListenerAdapter")
  @Primary
  MessageListenerAdapter Q1listenerAdapter(RabbitMQESIndexUpdateListener receiver) {
    return new MessageListenerAdapter(receiver);
  }

  @Bean(name = "RabbitMQQ2IndexUpdateListenerAdapter")
  MessageListenerAdapter Q2listenerAdapter(RabbitMQQ2IndexUpdateListener receiver) {
     return new MessageListenerAdapter(receiver);
  }

  @Bean
  public MessageConverter jackson2Converter() {
    Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter();
    ObjectMapper mapper = new ObjectMapper();
    mapper.registerModule(new JodaModule());
    converter.setJsonObjectMapper(mapper);
    return converter;
  }

请帮忙。
