因为 SpringBoot 已经内置了对 ActiveMQ 的支持，所以直接引入依赖 spring-boot-starter-activemq 就行。整体项目结构如下：
1、pom.xml 文件

/**
* Created by yz.shi on 2018/4/9.
*/
@Component
public class ActiveMQClient {
// 使用JmsListener配置消费者监听的队列，其中text是接收到的消息
@JmsListener(destination = "mytest.queue")
public void receiveQueue(String text) {
if(!StringUtils.isEmpty(text)){
System.out.println("ActiveMQServer收到的报文为:"+text);

}
4、消息接收类
package com.yuezhong.activemq.server;
import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import javax.jms.Destination;
/**
* Created by yz.shi on 2018/4/9.
*/
@Component
@EnableScheduling
public class ActiveMQServer {
@Autowired
private JmsTemplate jmsTemplate;
static int index = 0;
Destination destination = new ActiveMQQueue("mytest.queue");
@Scheduled(fixedDelay = 5000) // 5s执行一次 只有无参的方法才能用该注解
public void sendMessage() {
index++;
String message = "shiyuezhong" + index;
this.jmsTemplate.convertAndSend(destination, message);
}
}
5、ActivemqApplication
package com.yuezhong;

@SpringBootApplication
public class ActivemqApplication {
public static void main(String[] args) {
SpringApplication.run(ActivemqApplication.class, args);
}
}
另： Producer
package com.yuezhong.queue.producer;
import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.scheduling.annotation.Scheduled;

*/

*
* @param destination 发送到的队列
* @param message 待发送的消息
*/
public void convertAndSend(Destination destination, final String message) {
jmsTemplate.convertAndSend(destination, message);
}
/**
* 发送消息（定时发送队列）
*/
static int i = 100;
Destination destination = new ActiveMQQueue("yzshi_queue");
@Scheduled(fixedDelay = 5000) // 5s执行一次 只有无参的方法才能用该注解
public void convertAndSend() {
i++;
String message = "这是定时任务queueProducer发送的第" + i + "个消息！";
jmsTemplate.convertAndSend(destination, message);
}
}
package com.yuezhong.queue.consumer;

import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;
/**

*/
@Component
public class ConsumerB {
/**
* 使用JmsListener配置消费者监听的队列
*
* @param text 接收到的消息
*/
@JmsListener(destination = "yzshi_queue")
@SendTo("out.queue")
public String receiveQueue(String text) {
System.out.println("----------------Consumer-B : 收到的报文为:" + text);
return text;
}
@JmsListener(destination = "yzshi_queue")
public void printReceiveQueue(String text) {
System.out.println("+++++++++++++++++Consumer-B : 收到的报文为:" + text);
}
}
ConsumerC
package com.yuezhong.queue.consumer;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
/**

System.out.println("Consumer-C : 从out.queue队列收到的回复报文为:" + text);
}
}
