嘗試使用 Java (JMS) 中的選擇器在 Tibco EMS 上使用持久消息時遇到問題

Question

所以我試圖通過帶有消息 ID 選擇器的 JMS 使用來自 Tibco EMS 代理的消息。 如果消息是 NON_PERSISTENT，我可以通過它們的 JMSMessageID 來選擇它們，並且一切正常。

如果消息是持久的，則選擇器不會檢索任何內容。 我已經在 Apache ActiveMQ 上嘗試了相同的代碼，它在兩種情況下都有效。 我已經通過了 EMS 樣品，但看不到任何明顯的東西。 想知道是否有一些 EMS 設置可能會影響此...

如果我省略了選擇器，那么無論 DeliveryMode 是什么，消息都會被正確使用。

這是我用來重現它的內容。

任何幫助將非常感激 ：）

package com;

import javax.jms.*;
import com.tibco.tibjms.TibjmsConnectionFactory;

public class JMSTest {
    String msgIdPersistent = "";
    String msgIdNon_Persistent = "";
    String serverUrl = "tcp://localhost:7222";
    String queueName = "test";

    public static void main(String[] args) {
        JMSTest test = new JMSTest();
        try {
            test.publish();
            test.deleteBySelector();
        }catch(Exception ex) {
            ex.printStackTrace();
        }
    }

    public void deleteBySelector() throws Exception {
        // Create connection and session
        ConnectionFactory factory = new TibjmsConnectionFactory(serverUrl);
        Connection connection = factory.createConnection();
        connection.start();
        Session session = connection.createSession();

        // Delete non-persistent
        //
        String selectorNonPersist  = "JMSMessageID='" + msgIdNon_Persistent + "'";
        MessageConsumer nonPersistReceiver = session.createConsumer(session.createQueue(queueName), selectorNonPersist);
        Message nonPersistMsg = null;
        nonPersistMsg = nonPersistReceiver.receive(1000);
        System.out.println("NON PERSISTENT SELECTOR:  " + ((nonPersistMsg!=null) ? "SUCCESS" : "FAIL"));

        // Delete Persistent - **** THIS DOESN'T WORK *****
        //
        String selectorPersist  = "JMSMessageID='" + msgIdPersistent + "'";
        MessageConsumer persistReceiver = session.createConsumer(session.createQueue(queueName), selectorPersist);
        Message persistMsg = null;
        persistMsg = persistReceiver.receive(1000);
        System.out.println("PERSISTENT SELECTOR:  " + ((persistMsg!=null) ? "SUCCESS" : "FAIL"));   
    }

    public void publish() throws Exception {
        ConnectionFactory factory = new com.tibco.tibjms.TibjmsConnectionFactory(serverUrl);
        Connection connection = factory.createConnection();
        connection.start();
        Session session = connection.createSession(javax.jms.Session.AUTO_ACKNOWLEDGE);
        Destination destination = session.createQueue("test");

        // Send persistent message
        //
        System.out.println("Persistent publish");
        MessageProducer producerPersistent = session.createProducer(null);
        producerPersistent.setDeliveryMode(DeliveryMode.PERSISTENT);
        TextMessage messagePersistent = session.createTextMessage("PERSISTENT");
        producerPersistent.send(destination, messagePersistent);
        msgIdPersistent = messagePersistent.getJMSMessageID();
        System.out.println("\tMsgId=" + msgIdPersistent);

        // Send Non Persistent message
        //
        System.out.println("NON Persistent publish");
        MessageProducer producernonPersistent = session.createProducer(destination);
        producernonPersistent.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
        TextMessage messageNonPersistent = session.createTextMessage("NON_PERSISTENT");
        producernonPersistent.send(messageNonPersistent);
        msgIdNon_Persistent = messageNonPersistent.getJMSMessageID();
        System.out.println("\tMsgId=" + msgIdNon_Persistent);

        // Clean up
        session.close();
        connection.close();

        System.out.println("Done publish\n");
    }
}

我從中得到的輸出是：

    Persistent publish
        MsgId=ID:EMS-SERVER.3D856ECE827932:1
    NON Persistent publish
        MsgId=ID:EMS-SERVER.3D856ECE827932:2
    Done publish

    NON PERSISTENT SELECTOR:  SUCCESS
    PERSISTENT SELECTOR:  FAIL

我已經確認它是 8.2.x 中的一個錯誤。 我升級到 8.3.x 並且運行良好。
