未在JMS中接收待处理消息

Question

我正在使用ActiveMQ和JMS

我在队列中创建了一个ObjectMessage。我无法收到它。

查看Queue上已有的消息

我的接收消息代码是

public class RecieveObjectQueue {

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");


        try {
            ConnectionFactory connFactory=(ConnectionFactory) ctx.getBean("connectionFactory");

            Connection connection=connFactory.createConnection();
            connection.start();

        Session session=connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        Queue queue = new ActiveMQQueue(SendObjectQueue.OBJECT_QUEUE);

        MessageConsumer messageConsumer=session.createConsumer(queue);
        //          messageConsumer.receive();

        messageConsumer.setMessageListener(new MessageListener() {

            @Override
            public void onMessage(Message message) {
                ActiveMQObjectMessage activeMsg=(ActiveMQObjectMessage) message;
                /*if(message instanceof Car){
                    Car car=(Car) message;
                    System.out.println("Recieved Car=>"+car);
                }else{
                    System.out.println("Message is not a car object!!!");
                }*/

            }
        });
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

如果需要更多清晰度或代码，请提出要求。

您正在使用此代码消费（并丢弃）消息...

messageConsumer.receive();
