Spring Boot ActiveMQ

代码地址：https://github.com/huiyiwu/spring-boot-message/spring-boot-activemq

1. 添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
    <version>2.2.5.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.apache.activemq</groupId>
	<artifactId>activemq-pool</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-client</artifactId>
</dependency>

2. application.yaml

spring:
  activemq:
    user: admin
    password: admin
    queue-name: huchx.queue
    topic-name: huchx.topic
    broker-url: tcp://localhost:61616
    in-memory: false

3. 启动类添加@EnableJms

@SpringBootApplication
@EnableJms //启动消息队列
public class ActiveMQApp
{
    public static void main( String[] args )
    {
        SpringApplication.run(ActiveMQApp.class,args);
    }
}

4. ActiveMQ配置

/**
 * Author: Huchx
 * Date: 2021/1/12 10:37
 */
@Configuration
public class ActiveMQConfig {

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

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

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

    @Value("${spring.activemq.queue-name}")
    private String queueName;

    @Value("${spring.activemq.topic-name}")
    private String topicName;

    @Bean(name = "queue")
    public Queue queue() {
        return new ActiveMQQueue(queueName);
    }

    @Bean(name = "topic")
    public Topic topic() {
        return new ActiveMQTopic(topicName);
    }

    @Bean
    public ConnectionFactory connectionFactory(){
        return new ActiveMQConnectionFactory(username, password, brokerUrl);    }

    @Bean
    public JmsMessagingTemplate jmsMessageTemplate(){
        return new JmsMessagingTemplate(connectionFactory());
    }

    // 在Queue模式中，对消息的监听需要对containerFactory进行配置
    @Bean("queueListener")
    public DefaultJmsListenerContainerFactory queueJmsListenerContainerFactory(ConnectionFactory connectionFactory){
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory());
        factory.setPubSubDomain(false);
        return factory;
    }

    //在Topic模式中，对消息的监听需要对containerFactory进行配置
    @Bean("topicListener")
    public DefaultJmsListenerContainerFactory topicJmsListenerContainerFactory(ConnectionFactory connectionFactory){
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory());
        factory.setPubSubDomain(true);
        return factory;
    }
}

5. 消息生产者

/**
 * Author: Huchx
 * Date: 2021/1/12 11:03
 */
@RestController
public class ProducerController {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    Queue queue;

    @Autowired
    Topic topic;

    /**
     * 点对点发送
     * @return
     */
    @RequestMapping("queue")
    public String queue(){
        this.jmsMessagingTemplate.convertAndSend(this.queue,"Queue Send");
        return "Queue Success Send";
    }

    /**
     * 发布-订阅模式发送
     * @return
     */
    @RequestMapping("topic")
    public String topic(){
        this.jmsMessagingTemplate.convertAndSend(this.topic,"Topic Send");
        return "Topic Success Send";
    }
}

6. 消息消费者

• QueueConsumerListener.java

/**
 * Author: Huchx
 * Date: 2021/1/12 11:18
 */
@Component
public class QueueConsumerListener {

    @JmsListener(destination = "${spring.activemq.queue-name}",containerFactory = "queueListener")
    public void readActiveQueue(String msg){
        System.out.println("queue接收到消息："+msg);
    }
}

• TopicConsumerListener.java

/**
 * Author: Huchx
 * Date: 2021/1/12 11:19
 */
@Component
public class TopicConsumerListener {

    @JmsListener(destination = "${spring.activemq.topic-name}",containerFactory = "topicListener")
    public void topicRecive(String msg){
        System.out.println("topic接收到消息："+msg);
    }
}
