Question

我的代码如下：

@Configuration
public class RabbitMqCommonsConfig
{
    @Value(AmqpConstants.EXCHANGE)
    private String exchangeName;

    @Bean
    DirectExchange exchange()
    {
        return new DirectExchange(exchangeName);
    }

    @Bean
    public MessageConverter jsonMessageConverter()
    {
        return new Jackson2JsonMessageConverter();
    }

    @Bean
    public SimpleRabbitListenerContainerFactory jsaFactory(ConnectionFactory connectionFactory,
        SimpleRabbitListenerContainerFactoryConfigurer configurer)
    {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        factory.setMessageConverter(jsonMessageConverter());

        return factory;
    }

    @Bean
    public MessageProducer messageProducer(AmqpTemplate amqpTemplate)
    {
        return new MessageProducer(amqpTemplate);
    }
}

MessageProducer类：

@Component
public class MessageProducer
{
    private static final Logger logger = LoggerFactory.getLogger(MessageProducer.class);
    private AmqpTemplate amqpTemplate;

    @Autowired
    public MessageProducer(AmqpTemplate amqpTemplate)
    {
        this.amqpTemplate = amqpTemplate;
    }

    public void convertAndSend(String exchangeName, String routingKey, Object message)
    {
        if (message == null)
        {
            logger.warn("Parameter 'message' was null. Omitting sending of message.");
            return;
        }

        this.amqpTemplate.convertAndSend(exchangeName, routingKey, message);
        logger.debug("Sent message to exchange '{}' with routingKey '{}': '{}'", exchangeName, routingKey, message);
    }

    public <T> T convertSendAndReceive(String exchangeName, String routingKey, Object message)
    {
        if (message == null)
        {
            logger.warn("Parameter 'message' was null. Omitting sending of message to exchange '{}' with routingKey '{}'.",
                exchangeName, routingKey);
            return null;
        }

        T result = (T) amqpTemplate.convertSendAndReceive(exchangeName, routingKey, message);

        if (result != null)
        {
            logger.debug("Sent and received message to exchange '{}' with routingKey '{}'. Sent: '{}' - Received: '{}'",
                exchangeName, routingKey, message, result);
        }
        else
        {
            throw new CommunicationException(
                String.format("Response from message bus was 'null' (eventually due to timeout). " +
                              "Exchange Name: '%s' - Routing Key: '%s' - Message: '%s'", exchangeName,
                    routingKey, message));
        }

        return result;
    }
}

在开发环境中，我没有任何错误，在生产环境中，我遇到了以上错误。

任何人都可以答复在生产环境中为什么会发生此问题的原因。预先感谢。
