Spring AMQP:RabbitAdmin&&声明

二.配置类

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

@Configuration public class RabbitMQConfig {     @Bean     public ConnectionFactory connectionFactory(){         CachingConnectionFactory connectionFactory = new CachingConnectionFactory();         connectionFactory.setAddresses("192.168.10.132:5672");         connectionFactory.setUsername("guest");         connectionFactory.setPassword("guest");         connectionFactory.setVirtualHost("/");         return connectionFactory;     }       @Bean     public RabbitAdmin rabbitAdmin(ConnectionFactory connectionFactory){         RabbitAdmin rabbitAdmin = new RabbitAdmin(connectionFactory);         //autoStartup必须要设置为true,否则Spring容器不会加载RabbitAdmin类         rabbitAdmin.setAutoStartup(true);         return rabbitAdmin;     } }

三.RabbitAdmin测试

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

@SpringBootTest class SpringAmqpApplicationTests {       @Autowired     private RabbitAdmin rabbitAdmin;       @Test     public void testAdmin(){         //声明交换机         rabbitAdmin.declareExchange(new DirectExchange("admin.direct",false,false));         //声明队列         rabbitAdmin.declareQueue(new Queue("admin.queue",false));         rabbitAdmin.declareExchange(new DirectExchange("admin.topic",false,false));         rabbitAdmin.declareQueue(new Queue("admin.topic.queue",false));         //队列与交换机绑定         rabbitAdmin.declareBinding(                 new Binding("admin.queue",//Queue名                         Binding.DestinationType.QUEUE,//QUEUE绑定                         "admin.direct",//exchange名                         "direct", //路由                         new HashMap<>()));//参数         //链式编程         rabbitAdmin.declareBinding(                 BindingBuilder.bind(new Queue("admin.topic.queue",false))                 .to(new TopicExchange("admin.topic",false,false))                 .with("topic.#")         );         //清空队列         rabbitAdmin.purgeQueue("admin.topic.queue",false);     } }

 四.声明

　使用Spring AMQP可以使用如下方式去声明Exchange、queue。

　在配置类中加入Bean的方式。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

@Bean public TopicExchange topicExchange(){     return new TopicExchange("amqp.bean.topic",true,false); }   @Bean public Queue queue(){     return new Queue("queue",true) ; }   @Bean public Binding binding(){     return BindingBuilder.bind(this.queue()).to(topicExchange()).with("amqp.#"); }

　　运行springboot test方法，会发现控制台以及将exchange和queue创建完成。
