我正在使用ActiveMQ Artemis管理API来使用有关正在使用的队列以及有多少消费者的信息。

由于我正在缓存ClientRequest estor，activemq.management.*队列上的消息计数会不断增加。虽然我定义了到期延迟，但队列上的消息不会被丢弃。

有人能解释一下为什么吗？

我希望消息被消费，然后消失。

private ServerLocator locator;
private ClientSessionFactory defaultFactory;
private ClientSession session;
private ClientRequestor requestor;

public ManagementHelper(String defaultURL) {
    this.locator = ActiveMQClient.createServerLocator(defaultURL);
    this.defaultFactory = locator.createSessionFactory();
    this.session = factory.createSession(this.username, this.password, false, true, true, locator.isPreAcknowledge(), locator.getAckBatchSize());
    this.requestor = new ClientRequestor(session, "activemq.management");
}


@Scheduled(fixedRateString = "20000")
public void getConsumerNbos(ClientSessionFactory factory, ServerLocator locator) {
    ClientMessage message = session.createMessage(false);
    ManagementHelper.putOperationInvocation(message, ResourceNames.BROKER, listAllConsumersAsJSON);
    session.start();

    ClientMessage replyConsumer = requestor.request(message);
    String resultJSON = (String) ManagementHelper.getResult(replyConsumer, String.class);

    ClientMessage message2 = session.createMessage(false);
    ManagementHelper.putOperationInvocation(message2, ResourceNames.BROKER, MANAGEMENT_OPERATION_QUEUES);

    ClientMessage replyQueueNames = requestor.request(message2);
    Object[] objQueueNames = (Object[]) ManagementHelper.getResult(replyQueueNames);
}
