Question

我需要从ActiveMQ队列中使用JMS消息并将其发布到Azure Service Bus主题。我在这个项目中使用了Spring Boot，并使用Apache qpid通过AMQP协议连接Service Bus。

我面临的问题是，在将消息发布到Service Bus Topic期间消耗来自ActiveMQ的消息后，如果由于任何原因发生异常，我将无法在ActiveMQ中保留消息。我希望ActiveMQ保留消息，直到我能够在Service Bus中发布消息。我尝试在侦听器容器工厂中使用确认作为Session.CLIENT_ACKNOWLEDGE，但在异常的某处，它返回成功，导致ActiveMQ丢弃消息。但是，ActiveMQ能够重试发送7次，但之后只丢弃消息。

以下是我的代码详细信息。我必须使用2个配置类连接ActiveMQ和Service Bus，如下所示。

@Configuration
@EnableJms
public class RecevierConfig {

    private final Logger logger = LoggerFactory.getLogger(RecevierConfig.class);

    @Value("${activemq.host}")
    private String activemqHost;

    @Value("${activemq.protocol}")
    private String activemqProtocol;

    @Value("${activemq.port}")
    private String activemqPort;

      @Bean
      public ActiveMQConnectionFactory activeMQConnectionFactory() {
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
        logger.info("Broker URL : "+activemqProtocol+"://"+activemqHost+":"+activemqPort);
        activeMQConnectionFactory.setBrokerURL(activemqProtocol+"://"+activemqHost+":"+activemqPort);

        return activeMQConnectionFactory;
      }

      @Bean
      public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(activeMQConnectionFactory());
        factory.setConcurrency("3-10");
        factory.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE);
        factory.setErrorHandler(new DefaultErrorHandler());
        return factory;

      }

      @Bean
      public QueueReceiver receiver() {
        return new QueueReceiver();
      }

}

下面是为Service Bus连接创建ConnectionFactory和jmsTemplate以发布消息。

@Configuration
public class MessagingConfig {

      @Value("${spring.application.name}")
        private String clientId;


        @Bean
        @Primary
        public ConnectionFactory jmsConnectionFactory(MessageStoreDetails details) throws UnsupportedEncodingException {
            JmsConnectionFactory jmsConnectionFactory = new JmsConnectionFactory(details.getSBUrlString());
            jmsConnectionFactory.setUsername(details.getUsername());
            jmsConnectionFactory.setPassword(details.getPassword());
            jmsConnectionFactory.setClientID(clientId);
           // jmsConnectionFactory.setReceiveLocalOnly(true);
            return new CachingConnectionFactory(jmsConnectionFactory);
        }

        @Bean
        public JmsTemplate jmsTemplate(ConnectionFactory jmsConnectionFactory) {
            JmsTemplate returnValue = new JmsTemplate();
            returnValue.setConnectionFactory(jmsConnectionFactory);
            return returnValue;
        }

}

以下是QueueReceiver从ActiveMQ接收消息的代码

@Service
public class QueueReceiver {

    private final Logger logger = LoggerFactory.getLogger(QueueReceiver.class);

    @Autowired
    private TopicPublisher topicPublisher;

    @JmsListener(destination = "${activemq.queue}")
    public void receiveMessage(Message message) {

        try {
            logger.info("*****Received message from ActiveMQ queue : " + message.getJMSMessageID());
            topicPublisher.sendMessage(message);
            message.acknowledge();

        } catch (Exception e) {
            //logger.error(e.toString());
            throw new MessageProcessingException(e.toString());
        }
    }
}

下面是发布消息的类

@Service
public class TopicPublisher {

    private final Logger logger = LoggerFactory.getLogger(TopicPublisher.class);

    @Value("${servicebus.topic}")
    private String topic;

    @Autowired
    private JmsTemplate jmsTemplate;

    public void sendMessage(javax.jms.Message message) throws Exception {
           logger.info("#### Sending message to Service Bus Topic : "+ topic +" Message ID: "+ message.getJMSMessageID());
           jmsTemplate.convertAndSend(topic, message);
           logger.info("**** Message Sent to Service Bus Topic : "+ topic +" Message ID: "+ message.getJMSMessageID());
    }

}

从ActiveMQ和发布到Azure Service Bus主题的消息
