使用来自 RabbitMQ 的消息时流标头无效

Question

我们使用RabbitMQ 作为消息代理。为了与队列通信，我们使用RabbitMQ JMS client 的JMS 实现。我们为生产者和消费者使用 JMS 客户端。问题出在消费者尝试从队列中读取消息时。它引发以下异常。请告诉我如何解决此问题。

为了能够读回消息，您需要在您的消费者中设置一个 RMQDestination，就像在您的生产者中一样

像这样：

RMQConnectionFactory connectionFactory = new RMQConnectionFactory();
connectionFactory.setUsername("guest");
connectionFactory.setPassword("guest");
connectionFactory.setVirtualHost("/");
connectionFactory.setHost("localhost");

RMQDestination jmsDestination = new RMQDestination();
jmsDestination.setAmqp(true);
jmsDestination.setAmqpQueueName("rabbitQueueName");

Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
RMQMessageConsumer consumer = (RMQMessageConsumer)session.createConsumer(jmsDestination);
