activemq.properties内容:
brokerURL=tcp://127.0.0.1:61616
activemq.userName=admin
activemq.password=admin
queue.address=queue
topic.address=topic
spring与activemq整合的文件,由于此文件我是直接在spring与spring MVC整合的文件spring-mvc.xml中引入的,我已经在spring-mvc.xml中全局扫描含有注解的文件了,所以在这不需要扫描有注解的文件了:

消息消费者文件的内容:
QueueConsumer1.java文件:
package com.cn.common.jmsConsumer; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; import org.springframework.stereotype.Component; @Component public class QueueConsumer1 implements MessageListener{ @Override public void onMessage(Message message) { try { TextMessage text = null; if(message instanceof TextMessage){ text = (TextMessage) message; System.out.println("QueueConsumer1接收到消息:"+text.getText()); } } catch (JMSException e) { e.printStackTrace(); } } }

下面就是在我们需要发送消息的java文件中依赖注入QueueProducer发送点对点消息或TopicProducer发送发布订阅主题消息了。
