SpringBoot整合ActiveMQ

 

一. 安装ActiveMQ

到Apache官方网站下载最新的ActiveMQ的安装包,并解压到本地目录下,下载链接如下:http://activemq.apache.org/download.html,解压后的目录结构如下:

bin目录结构如下:

如果我们是32位的机器,就双击win32目录下的activemq.bat,如果是64位机器,则双击win64目录下的activemq.bat,运行结果如下:

启动成功!成功之后在浏览器输入http://127.0.0.1:8161/地址,可以看到ActiveMQ的管理页面,用户名和密码默认都是admin,如下:

二、新建spring boot工程,并加入JMS(ActiveMQ)依赖

 

三、工程结构

 

pom依赖如下:

46             </plugins>  
47         </build>  
48     </project>  
复制代码

四、修改application.properties配置文件

1     ## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`  
2     # failover:(tcp://localhost:61616,tcp://localhost:61617)  
3     # tcp://localhost:61616  
4     spring.activemq.broker-url=tcp://localhost:61616  
5     spring.activemq.in-memory=true  
6     spring.activemq.pool.enabled=false  

五、消息生产者

复制代码
 1 package com.chhliu.springboot.jms;  
 2   
 3 import javax.jms.Destination;  
 4   
 5 import org.springframework.beans.factory.annotation.Autowired;  
 6 import org.springframework.jms.core.JmsMessagingTemplate;  
 7 import org.springframework.stereotype.Service;  
 8   
 9 @Service("producer")  
10 public class Producer {  
11     @Autowired // 也可以注入JmsTemplate,JmsMessagingTemplate对JmsTemplate进行了封装  
12     private JmsMessagingTemplate jmsTemplate;  
13     // 发送消息,destination是发送到的队列,message是待发送的消息  
14     public void sendMessage(Destination destination, final String message){  
15         jmsTemplate.convertAndSend(destination, message);  
16     }  
17 } 
复制代码

 

六、消息消费者

复制代码
 1     package com.chhliu.springboot.jms;  
 2       
 3     import org.springframework.jms.annotation.JmsListener;  
 4     import org.springframework.stereotype.Component;  
 5       
 6     @Component  
 7     public class Consumer {  
 8             // 使用JmsListener配置消费者监听的队列,其中text是接收到的消息  
 9         @JmsListener(destination = "mytest.queue")  
10         public void receiveQueue(String text) {  
11             System.out.println("Consumer收到的报文为:"+text);  
12         }  
13     }  
复制代码

 

 消费者2的代码同上,注意,消息消费者的类上必须加上@Component,或者是@Service,这样的话,消息消费者类就会被委派给Listener类,原理类似于使用SessionAwareMessageListener以及MessageListenerAdapter来实现消息驱动POJO

七、测试

复制代码
 1     package com.chhliu.springboot.jms;  
 2       
 3     import javax.jms.Destination;  
 4       
 5     import org.apache.activemq.command.ActiveMQQueue;  
 6     import org.junit.Test;  
 7     import org.junit.runner.RunWith;  
 8     import org.springframework.beans.factory.annotation.Autowired;  
 9     import org.springframework.boot.test.context.SpringBootTest;  
10     import org.springframework.test.context.junit4.SpringRunner;  
11       
12     @RunWith(SpringRunner.class)  
13     @SpringBootTest  
14     public class SpringbootJmsApplicationTests {  
15           
16         @Autowired  
17         private Producer producer;  
18           
19         @Test  
20         public void contextLoads() throws InterruptedException {  
21             Destination destination = new ActiveMQQueue("mytest.queue");  
22               
23             for(int i=0; i<100; i++){  
24                 producer.sendMessage(destination, "myname is chhliu!!!");  
25             }  
26         }  
27       
28     }  
复制代码

测试结果如下:

复制代码
 1     Consumer2收到的报文为:myname is chhliu!!!  
 2     Consumer收到的报文为:myname is chhliu!!!  
 3     Consumer2收到的报文为:myname is chhliu!!!  
 4     Consumer收到的报文为:myname is chhliu!!!  
 5     Consumer2收到的报文为:myname is chhliu!!!  
 6     Consumer收到的报文为:myname is chhliu!!!  
 7     Consumer2收到的报文为:myname is chhliu!!!  
 8     Consumer收到的报文为:myname is chhliu!!!  
 9     Consumer2收到的报文为:myname is chhliu!!!  
10     Consumer收到的报文为:myname is chhliu!!!  
11     Consumer2收到的报文为:myname is chhliu!!!  
12     Consumer收到的报文为:myname is chhliu!!!  
13     Consumer2收到的报文为:myname is chhliu!!!  
复制代码

经过上面的几个步骤,spring boot和Jms就基本上整合完成了,是不是使用起来很方便了!

八、实现双向队列

1、下面首先来对Consumer2这个消费者来进行下改造,代码如下:

复制代码
 1     package com.chhliu.springboot.jms;  
 2       
 3     import org.springframework.jms.annotation.JmsListener;  
 4     import org.springframework.messaging.handler.annotation.SendTo;  
 5     import org.springframework.stereotype.Component;  
 6       
 7     @Component  
 8     public class Consumer2 {  
 9       
10         @JmsListener(destination = "mytest.queue")  
11         @SendTo("out.queue")  
12         public String receiveQueue(String text) {  
13             System.out.println("Consumer2收到的报文为:"+text);  
14             return "return message"+text;  
15         }  
16     }  
复制代码

从上面的代码可以看出,我们在receiveQueue方法上面多加了一个注解@SendTo("out.queue"),该注解的意思是将return回的值,再发送到"out.queue"队列中,该队列中的消息,就是我们返回的值!

九、对Producer进行改造

通过上面的示例,我们现在对Producer进行改造,使其既能生产报文,又能消费队列中的报文,代码如下:

复制代码
 1     package com.chhliu.springboot.jms;  
 2       
 3     import javax.jms.Destination;  
 4       
 5     import org.springframework.beans.factory.annotation.Autowired;  
 6     import org.springframework.jms.annotation.JmsListener;  
 7     import org.springframework.jms.core.JmsMessagingTemplate;  
 8     import org.springframework.stereotype.Service;  
 9       
10     @Service("producer")  
11     public class Producer {  
12         @Autowired  
13         private JmsMessagingTemplate jmsTemplate;  
14           
15         public void sendMessage(Destination destination, final String message){  
16             jmsTemplate.convertAndSend(destination, message);  
17         }  
18           
19         @JmsListener(destination="out.queue")  
20         public void consumerMessage(String text){  
21             System.out.println("从out.queue队列收到的回复报文为:"+text);  
22         }  
23     }  
复制代码

测试结果如下:

复制代码
 1     从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!  
 2     Consumer收到的报文为:myname is chhliu!!!  
 3     Consumer2收到的报文为:myname is chhliu!!!  
 4     从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!  
 5     Consumer收到的报文为:myname is chhliu!!!  
 6     Consumer2收到的报文为:myname is chhliu!!!  
 7     从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!  
 8     Consumer收到的报文为:myname is chhliu!!!  
 9     Consumer2收到的报文为:myname is chhliu!!!  
10     从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!
