需要为 activemq java 代码指定带有用户名和密码的队列名称

Question

我正在尝试编写连接到 activeMQ 队列的简单 java 代码，我在 activeMQ 站点中找到了 this resource online which basically follow the Hello World 示例。我正在尝试在队列名称旁边指定用户名和密码，但我无法在网上找到任何有用的资源，因此我们将不胜感激。

我在生产者代码中进行了以下更改，但我不确定如何指定工厂名称以及我是否正确指定了用户名和密码？

            // First create a connection
            InitialContext initCtx = new InitialContext();
            javax.jms.ConnectionFactory qcf = (javax.jms.ConnectionFactory) initCtx.lookup(factoryName);
            Connection connection = qcf.createConnection("admin","admin");
            connection.start();

这里有一个例子

        Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY,
                "org.apache.activemq.jndi.ActiveMQInitialContextFactory");
        props.setProperty(Context.PROVIDER_URL,
                "tcp://localhost:61616");
        props.put("topic." + "TOPICNAME", "TOPICNAME");
        InitialContext ic = new InitialContext(props);
        ConnectionFactory cf1 = (ConnectionFactory) ic.lookup("ConnectionFactory");
        writeDestination = (Topic) ic.lookup("TOPICNAME");
        writeDestConnection = cf1.createConnection("user", "pwd");
        writeDestConnection.setClientID("durableSubscriber_" + "TOPICNAME");
        writeDestSession = writeDestConnection.createSession(false,Session.AUTO_ACKNOWLEDGE);
        writeDestProducer = writeDestSession.createProducer(writeDestination);
        writeDestConnection.start();
        TextMessage message = writeDestSession.createTextMessage(json);
        message.setStringProperty("clientID", "ifYouNeed");
        writeDestProducer.send(message);

这是另一个没有 jndi 的例子：

    public static void main(String[] args) throws JMSException {
    Connection conn = null;
    try {
        ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory("tcp://localhost:61616");
        conn = cf.createConnection("user", "pwd");
        Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
        MessageConsumer consumer = session.createConsumer(session.createQueue("queueName"));
        conn.start();
        TextMessage msg = null;
        while ((msg = (TextMessage) consumer.receive()) != null) {
            System.out.println("Received message is: " + msg.getText());
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (conn != null) {
            try {
                conn.close();
            } catch (Exception e) {
            }
        }
    }
}
