SpringBoot集成activeMQ

1.添加依赖：

<!-- activemq --><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://192.168.74.135:61616spring.activemq.user=adminspring.activemq.password=adminspring.activemq.pool.enabled=truespring.activemq.pool.max-connections=50spring.activemq.pool.expiry-timeout=10000spring.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);        }    }}
