# SpringBoot集成activeMQ #

### 1.添加依赖： ###

<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.在application.properties中加入activemq的配置 ###

spring.activemq.broker-url=tcp://192.168.74.135:61616
    spring.activemq.user=admin
    spring.activemq.password=admin
    spring.activemq.pool.enabled=true
    spring.activemq.pool.max-connections=50
    spring.activemq.pool.expiry-timeout=10000
    spring.activemq.pool.idle-timeout=30000

### 3.创建一个消息生产者 ###

@Component
    public class JMSProducer { 
        @Autowired
        private JmsTemplate jmsTemplate;
    
        public void sendMessage(Destination destination,String message) {
            this.jmsTemplate.convertAndSend(destination,message);
        }
    }

### 4.创建一个消息消费者 ###

@Component
    public class JMSConsumer { 
        private final static Logger logger = LoggerFactory.getLogger(JMSConsumer.class);
    
        @JmsListener(destination = "springboot.queue.test")
        public void receiveQueue(String msg) {
            logger.info("接收到消息：{}",msg);
        }
    }

### 5.测试类 ###

public class JmsTest extends BaseTest{ 
        @Autowired
        private JMSProducer jmsProducer;
    
        @Test
        public void testJms() {
            Destination destination = new ActiveMQQueue("springboot.queue.test");
    
            for (int i=0;i<10;i++) {
                jmsProducer.sendMessage(destination,"hello,world!" + i);
            }
        }
    }

BaseTest代码如下：

@RunWith(SpringRunner.class)
    @SpringBootTest(classes = com.sample.activity.web.Application.class)
    public abstract class BaseTest { 
    }

### 6.发送和接收TOPIC消息 ###

默认只能发送和接收queue消息，如果要发送和接收topic消息，需要在application.properties文件中加入：

spring.jms.pub-sub-domain=true

发送和接收的代码同queue一样。  
但是这样有另外一个问题：无法发送和接收queue消息。那么如何同时支持发送和接收queue/topic消息呢？

### 7.支持同时发送和接收queue/topic ###

i. 新建一个JMS的配置类：

@Configuration
    public class JmsConfig { 
        public final static String TOPIC = "springboot.topic.test";
        public final static String QUEUE = "springboot.queue.test";
        @Bean
        public Queue queue() {
            return new ActiveMQQueue(QUEUE);
        }
    
        @Bean
        public Topic topic() {
            return new ActiveMQTopic(TOPIC);
        }
    
        // topic模式的ListenerContainer
        @Bean
        public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ConnectionFactory activeMQConnectionFactory) {
            DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
            bean.setPubSubDomain(true);
            bean.setConnectionFactory(activeMQConnectionFactory);
            return bean;
        }
        // queue模式的ListenerContainer
        @Bean
        public JmsListenerContainerFactory<?> jmsListenerContainerQueue(ConnectionFactory activeMQConnectionFactory) {
            DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
            bean.setConnectionFactory(activeMQConnectionFactory);
            return bean;
        }
    
    }

ii. 消息消费者的代码改成如下：

@Component
    public class JMSConsumer { 
        private final static Logger logger = LoggerFactory.getLogger(JMSConsumer.class);
    
        @JmsListener(destination = JmsConfig.TOPIC,containerFactory = "jmsListenerContainerTopic")
        public void onTopicMessage(String msg) {
            logger.info("接收到topic消息：{}",msg);
        }
    
        @JmsListener(destination = JmsConfig.QUEUE,containerFactory = "jmsListenerContainerQueue")
        public void onQueueMessage(String msg) {
            logger.info("接收到queue消息：{}",msg);
        }
    }

可以看到，这里指定了ConnectionFactory。

iii. 测试类：

public class JmsTest extends BaseTest{ 
        @Autowired
        private JMSProducer jmsProducer;
        @Autowired
        private Topic topic;
        @Autowired
        private Queue queue;
    
        @Test
        public void testJms() {
            for (int i=0;i<10;i++) {
                jmsProducer.sendMessage(queue,"queue,world!" + i);
                jmsProducer.sendMessage(topic, "topic,world!" + i);
            }
        }
    }
