How to get Spring RabbitMQ to create a new Queue?
Solution 1:
Older thread, but this still shows up pretty high on Google, so here's some newer information:
2015-11-23
Since Spring 4.2.x with Spring-Messaging and Spring-Amqp 1.4.5.RELEASE and Spring-Rabbit 1.4.5.RELEASE, declaring exchanges, queues and bindings has become very simple through an @Configuration class some annotations:
@EnableRabbit
@Configuration
@PropertySources({
@PropertySource("classpath:rabbitMq.properties")
})
public class RabbitMqConfig {
private static final Logger logger = LoggerFactory.getLogger(RabbitMqConfig.class);
@Value("${rabbitmq.host}")
private String host;
@Value("${rabbitmq.port:5672}")
private int port;
@Value("${rabbitmq.username}")
private String username;
@Value("${rabbitmq.password}")
private String password;
@Bean
public ConnectionFactory connectionFactory() {
CachingConnectionFactory connectionFactory = new CachingConnectionFactory(host, port);
connectionFactory.setUsername(username);
connectionFactory.setPassword(password);
logger.info("Creating connection factory with: " + username + "@" + host + ":" + port);
return connectionFactory;
}
/**
* Required for executing adminstration functions against an AMQP Broker
*/
@Bean
public AmqpAdmin amqpAdmin() {
return new RabbitAdmin(connectionFactory());
}
/**
* This queue will be declared. This means it will be created if it does not exist. Once declared, you can do something
* like the following:
*
* @RabbitListener(queues = "#{@myDurableQueue}")
* @Transactional
* public void handleMyDurableQueueMessage(CustomDurableDto myMessage) {
* // Anything you want! This can also return a non-void which will queue it back in to the queue attached to @RabbitListener
* }
*/
@Bean
public Queue myDurableQueue() {
// This queue has the following properties:
// name: my_durable
// durable: true
// exclusive: false
// auto_delete: false
return new Queue("my_durable", true, false, false);
}
/**
* The following is a complete declaration of an exchange, a queue and a exchange-queue binding
*/
@Bean
public TopicExchange emailExchange() {
return new TopicExchange("email", true, false);
}
@Bean
public Queue inboundEmailQueue() {
return new Queue("email_inbound", true, false, false);
}
@Bean
public Binding inboundEmailExchangeBinding() {
// Important part is the routing key -- this is just an example
return BindingBuilder.bind(inboundEmailQueue()).to(emailExchange()).with("from.*");
}
}
Some sources and documentation to help:
- Spring annotations
- Declaring/configuration RabbitMQ for queue/binding support
- Direct exchange binding (for when routing key doesn't matter)
Note: Looks like I missed a version -- starting with Spring AMQP 1.5, things get even easier as you can declare the full binding right at the listener!
Solution 2:
What seemed to resolve my issue was adding an admin. Here is my xml:
<rabbit:listener-container connection-factory="rabbitConnectionFactory" >
<rabbit:listener ref="orderQueueListener" queues="test.order" />
</rabbit:listener-container>
<rabbit:queue name="test.order"></rabbit:queue>
<rabbit:admin id="amqpAdmin" connection-factory="rabbitConnectionFactory"/>
<bean id="orderQueueListener" class="com.levelsbeyond.rabbit.OrderQueueListener">
</bean>
