3.Topic - 主题

</beans>

3.2 生产者

• 和队列的代码一样，只是在配置文件里面改了destination

3.3 消费者

• 和队列的代码一样，只是在配置文件里面改了destination

4.消费者 - 监听器

• 实现目标：在Spring里面实现消费者不启动，直接通过配置监听完成
• 类似于前面setMessageListenner实时间提供消息
• 注意：配置了监听器，那么启动生产者，就会自动消费，不需要再启动消费者了

4.1 编写监听器类

package com.qingsi.activemq.spring;import org.springframework.stereotype.Component;import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;@Component
public class MyMessageListener implements MessageListener {@Overridepublic void onMessage(Message message) {if (message instanceof TextMessage){TextMessage textMessage = (TextMessage) message;try {System.out.println("收到消息： " + textMessage.getText());} catch (JMSException e) {e.printStackTrace();}}}
}

4.2 配置监听器

• applicationContext.xml
