Turn: spring boot + ActiveMQ to implement message service

First of all, I found a good demo on github, here is for everyone to see:

https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-activemq

 

It is indeed possible to achieve the function, but when I query the queue on the default admin port of 8161, I find that there is no github-queue. Although the specific reason is not clear, the solution has been found. Here is my own implementation:

pox.xml ：

Java code  

1. <!-- ActiveMQ -->  
2.         <dependency>  
3.             <groupId>org.springframework</groupId>  
4.             <artifactId>spring-jms</artifactId>  
5.         </dependency>  
6.         <dependency>  
7.             <groupId>org.apache.activemq</groupId>  
8.             <artifactId>activemq-all</artifactId>  
9.             <version>5.13.2</version>  
10.         </dependency>  

application.properties：

Java code  

1. spring.activemq.in-memory=true  
2. spring.activemq.pooled=false  

 

 

Next is the configuration of jms, the first is the ActiveMQ4Config file:

Java code  

1. @EnableJms  
2. @Configuration  
3. public class ActiveMQ4Config {  
4.   
5.     @Bean  
6.     public Queue queue() {  
7.         return new ActiveMQQueue("github-queue");  
8.     }  
9.   
10.     @Bean  
11.     public ActiveMQConnectionFactory activeMQConnectionFactory (){  
12.         ActiveMQConnectionFactory activeMQConnectionFactory =  
13.                 new ActiveMQConnectionFactory(  
14.                         ActiveMQConnectionFactory.DEFAULT_USER,  
15.                         ActiveMQConnectionFactory.DEFAULT_PASSWORD,  
16. //                        "tcp://192.168.0.100:61616");  
17.                         ActiveMQConnectionFactory.DEFAULT_BROKER_URL);  
18.         return activeMQConnectionFactory;  
19.     }  
20.   
21. }  

注释掉的那行，可以用来指定activemq的broker地址。

 

接下来的Producer和Consumer与github上一样：

Java代码  

1. @Component  
2. public class Producer implements CommandLineRunner{  
3.   
4.     @Autowired  
5.     private JmsMessagingTemplate jmsMessagingTemplate;  
6.   
7.     @Autowired  
8.     private Queue queue;  
9.   
10.     @Override  
11.     public void run(String... args) throws Exception {  
12.         send("this message is send on begining!");  
13.         System.out.println("Message was sent to the Queue");  
14.     }  
15.   
16.     public void send(String msg) {  
17.         this.jmsMessagingTemplate.convertAndSend(this.queue, msg);  
18.     }  
19.   
20. }  

Java代码  

1. @Component  
2. public class Consumer {  
3.   
4.     @JmsListener(destination = "github-queue")  
5.     public void receiveQueue(String text) {  
6.         System.out.println(text);  
7.     }  
8.   
9. }  

 

This completes the configuration, and when the 8161 default admin queries, we can query our github-queue queue.

The specific test can be carried out by yourself, and the test case is no longer posted here.
