SpringBoot集成activeMQ

1.添加依赖：


    
        
     
      org.springframework.boot
      
     
      spring-boot-starter-activemq
      
     
     
     
      org.apache.activemq
      
     
      activemq-pool

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

@Componentpublic 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

@Componentpublic 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：

@Configurationpublic 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：

@Componentpublic 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); } } }
