Question

我使用WSO2 MB 2.0.1，我尝试将教程中提供的JMS Java订阅者扩展到是一个耐用的订户。然后停止jms客户端并向主题发送一些消息。但是当我启动jms客户端，它不会收到消息。

有人可以告诉我如何创建持久订阅者。我的要求是在jms用户上线时收到消息。

我的代码： public void subscribe（String topicName）{

    Properties initialContextProperties = new Properties();
    initialContextProperties.put("java.naming.factory.initial",
            "org.wso2.andes.jndi.PropertiesFileInitialContextFactory");
    String connectionString = "amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5672'";
    initialContextProperties.put("connectionfactory.qpidConnectionfactory", connectionString);
    initialContextProperties.put("topic.myWarning", "myWarning");

    try {
        InitialContext initialContext = new InitialContext(initialContextProperties);
        TopicConnectionFactory topicConnectionFactory =
                (TopicConnectionFactory) initialContext.lookup("qpidConnectionfactory");
        TopicConnection topicConnection = topicConnectionFactory.createTopicConnection();
        //topicConnection.setClientID("clientID");
        topicConnection.start();
        TopicSession topicSession =topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);

        //Topic topic = topicSession.createTopic(topicName);
        Topic topic =(Topic) initialContext.lookup(topicName);
        TopicSubscriber topicSubscriber =
                topicSession.createDurableSubscriber(topic, "tom");
        TextMessage receivedMessage = (TextMessage)topicSubscriber.receive();
        System.out.println(receivedMessage);
       // topicSubscriber.setMessageListener(new JCOMessageListener(
        //        topicConnection, topicSession, topicSubscriber));

    } catch (NamingException e) {
        e.printStackTrace();
    } catch (JMSException e) {
        e.printStackTrace();
    }
}

Answer 1

您的JMS客户端完全有效。

WSO2 MB 2.0.1中的持久主题订阅存在错误。我们已经修复了WSO2 MB 2.1.1版本，该版本将在今后一个月内发布。

感谢。
