ActiveMQ使用spring JmsTemplate生成和订阅消息（二）

生成类：

@Component("topicProvider")
public class TopicProvider {
    @Resource
    private JmsTemplate topicJmsTemplate;

    /**
     * 向指定的topic发布消息
     *
     * @param topic
     * @param msg
     */
    public void publish(final Destination topic, final String msg) {

        topicJmsTemplate.send(topic, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                System.out.println("topic name 是" + topic.toString()
                        + "，发布消息内容为:\t" + msg);
                return session.createTextMessage(msg);
            }
        });
    }
}

监听器：

public class TopicMessageListener implements MessageListener{
    public void onMessage(Message message) {
        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("订阅者1 \t" + tm.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

spirng配置：
