网络断开连接后，ActiveMQ 5 重新传送不起作用

Question

Frameworks :

• Java 1.7.0_191 and 1.8.0_181
• Spring 4.3.18.RELEASE
• ActiveMQ 5.14.5

Scenario :

Two clients and a server. Client 1 loses connection (due to network disconnect). A message is sent and consumed by client 2. Client 1 regains network connection. Now I was expecting a redelivery of the message to client 1. Although client 1 works fine now (getting all new messages) there is a gap where client 1 didn't get the update messages, so the client is not trustable anymore.

Is this by design or did I configure something wrong?

ServerBroker :

final String brokerURI = String.format("broker://(tcp://%s:%s)?brokerName=clientBroker", host, port);
final BrokerService brokerService = BrokerFactory.createBroker(brokerURI);
brokerService.setUseJmx(true);
brokerService.setDataDirectory(dataDirectory);
final LoggingBrokerPlugin loggingBrokerPlugin = new LoggingBrokerPlugin();
loggingBrokerPlugin.setLogConsumerEvents(true);
loggingBrokerPlugin.setLogProducerEvents(true);
brokerService.setPlugins(new BrokerPlugin[] { loggingBrokerPlugin });
brokerService.start();

ServerProducer :

final JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setPubSubDomain(true);
jmsTemplate.setExplicitQosEnabled(true);
jmsTemplate.setDeliveryMode(DeliveryMode.PERSISTENT);
jmsTemplate.setTimeToLive(600_000L);
final ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
activeMQConnectionFactory.setTrustedPackages(ImmutableList.of("my.package", "java"));
activeMQConnectionFactory.setBrokerURL(String.format("tcp://%s:%s", host, port));
jmsTemplate.setConnectionFactory(new PooledConnectionFactory(activeMQConnectionFactory));
jmsTemplate.convertAndSend(JmsQueueConstants.SERVER_UPDATE, new NotificationQueueEntry());

ClientConsumer :

@JmsListener(destination = JmsQueueConstants.SERVER_UPDATE)
public void receive(final NotificationQueueEntry msg) {
    process(msg);
}

@Bean
public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
    final DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    factory.setConnectionFactory(jmsConnectionFactory());
    factory.setPubSubDomain(true);
    factory.setSessionTransacted(true);
    factory.setCacheLevel(DefaultMessageListenerContainer.CACHE_CONSUMER);
    factory.setConcurrency("2");
    return factory;
}

private ConnectionFactory jmsConnectionFactory() {
    final ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
    activeMQConnectionFactory.setTrustedPackages(ImmutableList.of("my.package", "java"));
    activeMQConnectionFactory.setBrokerURL(String.format("failover:(tcp://%s:%s)?jms.closeTimeout=%d", host, port, 600_000));
    final RedeliveryPolicy redeliveryPolicy = new RedeliveryPolicy();
    redeliveryPolicy.setInitialRedeliveryDelay(10_000L);
    redeliveryPolicy.setRedeliveryDelay(1_000L);
    redeliveryPolicy.setMaximumRedeliveries(600);
    activeMQConnectionFactory.setRedeliveryPolicy(redeliveryPolicy);
    activeMQConnectionFactory.setTransportListener(new TransportListener() {
        
        @Override
        public void onCommand(final Object command) {
        }
        
        @Override
        public void onException(final IOException error) {
            connected = false;
        }
        
        @Override
        public void transportInterupted() {
            connected = false;
        }
        
        @Override
        public void transportResumed() {
            if (!connected) {
                reconnect();
            }
        }
        
    });
    return new PooledConnectionFactory(activeMQConnectionFactory);
}

connected and reconnect() are just to visibly show the disconnected state in the client, not actively reconnecting the ActiveMQ connection.

Answer 1

This is the expected behavior for a non-durable topic subscriber. When such a subscriber is not connected it will not receive any messages sent to the broker.

It's also worth noting that this is not what is typically referred to as "redelivery." Message redelivery is what happens when, for example, a message is consumed in a transaction and that transaction is rolled back and the message is then redelivered to the client to try again.
