spring-amqp結合使用rabbitmq
Spring AMQP提供了org.springframework.amqp.core.AmqpTemplate來發送與接收消息。AMQP模板實現支持發送與接收POJOs而非javax.jms.Message實例。他們還提供了一種方式來自定義用于編排對象的MessageConverter。Spring 與JMS用戶會發現JmsTemplate與新的AmqpTemplate之間的相似性。
下面的代碼片段介紹了如何聯合使用Spring AMQP與RabbitMQ處理同步消息。RabbitMQ是VMware的產品,并且是官方Spring AMQP示例中所用的默認AMQP實現。
Maven項目添加依賴包spring-rabbit
<dependencies> <dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring-rabbit</artifactId> <version>1.3.5.RELEASE</version> </dependency> </dependencies>
just Java
public static void main(final String... args) throws Exception {ConnectionFactory cf = new CachingConnectionFactory(); // set up the queue, exchange, binding on the broker RabbitAdmin admin = new RabbitAdmin(cf); Queue queue = new Queue("myQueue"); admin.declareQueue(queue); TopicExchange exchange = new TopicExchange("myExchange"); admin.declareExchange(exchange); admin.declareBinding( BindingBuilder.bind(queue).to(exchange).with("foo.*")); // set up the listener and container SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(cf); Object listener = new Object() { public void handleMessage(String foo) { System.out.println(foo); } }; MessageListenerAdapter adapter = new MessageListenerAdapter(listener); container.setMessageListener(adapter); container.setQueueNames("myQueue"); container.start(); // send something RabbitTemplate template = new RabbitTemplate(cf); template.convertAndSend("myExchange", "foo.bar", "Hello, world!"); Thread.sleep(1000); container.stop();
}</pre></div>
Or, the Spring way
1.applicationContext-amqp.xml
<rabbit:connection-factory id="connectionFactory" /><rabbit:template id="amqpTemplate" connection-factory="connectionFactory" exchange="myExchange" routing-key="foo.bar"/>
<rabbit:admin connection-factory="connectionFactory" />
<rabbit:queue name="myQueue" />
<rabbit:topic-exchange name="myExchange"> <rabbit:bindings> <rabbit:binding queue="myQueue" pattern="foo.*" /> </rabbit:bindings> </rabbit:topic-exchange>
<rabbit:listener-container connection-factory="connectionFactory"> <rabbit:listener ref="foo" method="listen" queue-names="myQueue" /> </rabbit:listener-container>
<bean id="foo" class="foo.Foo" /></pre></div>
2.Method Foo
public class Foo {public void listen(String foo) { System.out.println(foo); }
}</pre></div>
3.Method Main
public static void main(final String... args) throws Exception {AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-amqp.xml"); RabbitTemplate template = ctx.getBean(RabbitTemplate.class); template.convertAndSend("Hello, world!"); Thread.sleep(1000); ctx.destroy();
}</pre></div> </div>
