Active MQ入门2，Spring Boot整合Active MQ

Active MQ入门2，Spring Boot整合Active MQ

1、搭建Spring Boot项目

首先创建一个Spring Boot的项目，在pom文件中加入：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

加入Spring Boot 对Active MQ支持的starter包：starter-activemq
还有Active MQ的连接池：activemq-pool

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-pool</artifactId>
</dependency>

2、配置相关信息

在application.properties加入Active MQ的相关配置信息

spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.user=admin
spring.activemq.password=admin
spring.activemq.pool.enabled=true

3、编写配置类

Spring Boot 规定必须配置Active MQ的连接工厂，和Spring的配置方法一样，只不过这是注解与Java代码的方式进行配置

@Configuration
@EnableJms
public class ActiveMqConfiguration {

    @Value("${spring.activemq.user}")
    private String usrName;

    @Value("${spring.activemq.password}")
    private String password;

    @Value("${spring.activemq.broker-url}")
    private String brokerUrl;

    @Bean
    public ConnectionFactory connectionFactory(){
        ActiveMQConnectionFactory connectionFactory
                = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL(brokerUrl);
        connectionFactory.setUserName(usrName);
        connectionFactory.setPassword(password);
        return connectionFactory;
    }
    @Bean("jmsTopicListenerContainerFactory")
    public JmsListenerContainerFactory jmsTopicListenerContainerFactory(
            ConnectionFactory connectionFactory
    ){
        DefaultJmsListenerContainerFactory factory
                = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setPubSubDomain(true);
        return factory;
    }
}

4、发送端代码（生产者）

@Service
public class ProducerQueue {

    @Autowired
    private JmsMessagingTemplate jmsTemplate;//简单操作
    @Autowired
    private JmsTemplate template;//可以做更细微的控制

    // 发送消息，destination是发送到的队列，message是待发送的消息
    public void sendMessageByJmsMessagingTemplate(Destination destination, final String message){
        jmsTemplate.convertAndSend(destination, message);
    }
    
    public void sendMessageByJmsTemplate(Destination destination, final String message){
        template.send(destination, session -> {
            TextMessage msg = session.createTextMessage();
            msg.setText(message + "othre information");
            return msg;
        });
    }
}

5、接收端代码（消费者）

@Component
public class ConsumerAQueue {
    // 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 = "springboot.queue")
    public void receiveQueue(String text){
        System.out.println(this.getClass().getName()+" receive msg:"+text);
    }
}

6、编写测试类

首先我们启动Spring Boot程序。
然后我们在test目录下编写测试类

@RunWith(SpringRunner.class)
@SpringBootTest
public class AmSpringbootApplicationTests {

    @Autowired
    private ProducerQueue producerQueue;

    @Test
    public void testQueueNormal() {
        Destination destination
                = new ActiveMQQueue("springboot.queue");
        for(int i=0; i<3; i++){
            producerQueue.sendMessageByJmsMessagingTemplate(destination,
                    "NO:"+i+";my name is Mark!!!");
        }
    }
}
