Question

我为我的项目开发了两个Web应用程序作为生产者和消费者。除了一些消息处于挂起状态（我可以在浏览器/ UI中看到），即使在我的监听器消耗了所有消息之后，一切正常。

Exp： - 制作人发送10K，消费者收到10K，但我仍然可以看到约有1K的消息处于待处理状态。如果我在UI中单击清除选项，那么我的监听器再次监听那些待处理的消息。

减少预取政策会减少待处理的消息，但会影响我的消费者的表现。

制片人代码：

    @Bean
    public ActiveMQConnectionFactory connectionFactory(){
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL(env.getProperty(JioTUConstant.SYS_JMS_BROKER_URL));
        connectionFactory.setUseAsyncSend(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_USE_ASYNC_SEND)));
        connectionFactory.setAlwaysSessionAsync(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_ALWAYS_SESSION_ASYNC)));
        connectionFactory.setOptimizeAcknowledge(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_OPTIMIZE_ACK)));
        connectionFactory.setUserName(env.getProperty(JioTUConstant.SYS_JMS_USERNAME));
        connectionFactory.setPassword(env.getProperty(JioTUConstant.SYS_JMS_PASSWORD));
        return connectionFactory;
    }

    @Bean
    public CachingConnectionFactory cachingConnectionFactory(){
        CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
        cachingConnectionFactory.setTargetConnectionFactory(connectionFactory());
        cachingConnectionFactory.setSessionCacheSize(new Integer(env.getProperty(JioTUConstant.SYS_JMS_SESSION_CACHE_SIZE)));
        cachingConnectionFactory.setReconnectOnException(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_RECONNECT_ON_EXCEPTION)));
        return cachingConnectionFactory;
    }

    @Bean
    public JmsTemplate jmsTemplate(){
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setDeliveryMode(new Integer(env.getProperty(JioTUConstant.SYS_JMS_DELIVERY_MODE)));//DeliveryMode.NON_PERSISTENT=1 and DeliveryMode.PERSISTENT=2
        jmsTemplate.setSessionAcknowledgeMode(new Integer(env.getProperty(JioTUConstant.SYS_JMS_SESSION_ACK_MODE)));//Session.AUTO_ACKNOWLEDGE=1,Session.CLIENT_ACKNOWLEDGE=2,Session.DUPS_OK_ACKNOWLEDGE=3 and Session.SESSION_TRANSACTED=0
        jmsTemplate.setSessionAcknowledgeModeName(env.getProperty(JioTUConstant.SYS_JMS_SESSION_ACK_MODE_NAME));
        jmsTemplate.setSessionTransacted(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_SESSION_TRANSACTED)));
        jmsTemplate.setDefaultDestinationName(env.getProperty(JioTUConstant.SYS_JMS_LOG_QUEUE_NAME));
        jmsTemplate.setConnectionFactory(cachingConnectionFactory());
        return jmsTemplate;
    }

消费者代码：

    @Bean
    public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConcurrency(env.getProperty(JioTUConstant.SYS_JMS_CONCURRENT_LISTENER));
        factory.setConnectionFactory(cachingConnectionFactory());
        return factory;
    }

    @Bean
    public ActiveMQConnectionFactory connectionFactory(){
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL(env.getProperty(JioTUConstant.SYS_JMS_BROKER_URL));
        connectionFactory.setAlwaysSessionAsync(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_ALWAYS_SESSION_ASYNC)));
        connectionFactory.setOptimizeAcknowledge(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_OPTIMIZE_ACK)));
        connectionFactory.setUserName(env.getProperty(JioTUConstant.SYS_JMS_USERNAME));
        connectionFactory.setPassword(env.getProperty(JioTUConstant.SYS_JMS_PASSWORD));
        return connectionFactory;
    }

    @Bean
    public CachingConnectionFactory cachingConnectionFactory(){
        CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
        cachingConnectionFactory.setSessionCacheSize(new Integer(env.getProperty(JioTUConstant.SYS_JMS_SESSION_CACHE_SIZE)));
        cachingConnectionFactory.setReconnectOnException(new Boolean(env.getProperty(JioTUConstant.SYS_JMS_RECONNECT_ON_EXCEPTION)));
        cachingConnectionFactory.setTargetConnectionFactory(connectionFactory());
        return cachingConnectionFactory;
    }

ActiveMQ 5.14.0

即使在侦听器工作正常后，jms队列中的消息仍未处理？
