JMSListener選擇器不工作

Question

我有一個JMS生產者發送2種消息：業務邏輯和心跳信息。目前，兩者都由同一個接收器處理，但我現在正在嘗試通過使用選擇器爲每個接收器分配專用類。我遇到的問題是每當將選擇器添加到接收器時，它都會停止接收消息。這是我到目前爲止。爲簡單起見，我只增加了心臟的跳動代碼：

要發送信息，我有這樣的：

private void sendHeartBeat() { 
    this.buildTemplate().send(new HeartbeatMessageCreator(this.someId)); 
} 

private JmsTemplate buildTemplate() { 
    if (this.cachedJmsTemplate == null) { 
     final ActiveMQTopic activeMQTopic = new ActiveMQTopic(this.topic); 
     this.cachedJmsTemplate = new JmsTemplate(this.config.getCachedConnectionFactory()); 
     this.cachedJmsTemplate.setDefaultDestination(activeMQTopic); 
     this.cachedJmsTemplate.setPubSubDomain(true); 
    } 
    return this.cachedJmsTemplate; 
} 

HeartbeatMessageCreator：

class HeartbeatMessageCreator implements MessageCreator { 
private final String someID; 

HeartbeatMessageCreator(final String someID) { 
    this.someID = someID; 
} 

@Override 
public Message createMessage(final Session session) throws JMSException { 
    final Serializable message = new ZHeartBeat(this.someID); 
    final Message jmsMessage = session.createObjectMessage(message); 
    jmsMessage.setJMSType(message.getClass().getName()); 
    jmsMessage.setStringProperty("InternalMessageType", "HeartBeat"); // <-- Setting my separator here 

    return jmsMessage; 
} 

消費情況如下：

@Component 
public class MyListener { 

    @JmsListener(destination = "${myTopic}", containerFactory = "myJmsContainer", selector = "InternalMessageType = 'HeartBeat'") 
    public final void onMessage(final Message message) { 

    ... 

    } 
} 

在此配置中，消費者從未看到消息進入，但如果我刪除了sele ctor部分來自@JmsListener註釋，它們被交付。我不確定我在這裏做錯了什麼。任何想法 ？

它工作正常，我...

@SpringBootApplication 
public class So46453364Application implements CommandLineRunner { 

    public static void main(String[] args) throws Exception { 
     ConfigurableApplicationContext ctx = SpringApplication.run(So46453364Application.class, args); 
     Thread.sleep(10_000); 
     ctx.close(); 
    } 

    @Autowired 
    private JmsTemplate template; 

    @Override 
    public void run(String... arg0) throws Exception { 
     this.template.convertAndSend("foo", "foo", m -> { 
      m.setStringProperty("foo", "bar"); 
      return m; 
     }); 
     this.template.convertAndSend("foo", "foo", m -> { 
      m.setStringProperty("foo", "baz"); 
      return m; 
     }); 
    } 

    @JmsListener(destination = "foo", selector = "foo = 'bar'") 
    public void bar(Message in) { 
     System.out.println("bar: " + in); 
    } 

    @JmsListener(destination = "foo", selector = "foo = 'baz'") 
    public void baz(Message in) { 
     System.out.println("baz: " + in); 
    } 

} 

結果
