yml配置

spring:
  rabbitmq:
    host: localhost
    port: 5672
    virtual-host: /itcast
    username: heima
    password: heima

绑定交换机和队列

@Configuration
public class RabbitMQConfig {
    //交换机名称
    public static final String ITEM_TOPIC_EXCHANGE = "item_topic_exchange";
    //队列名称
    public static final String ITEM_QUEUE = "item_queue";

    //声明交换机
    @Bean("itemTopicExchange")
    public Exchange topicExchange(){
        return ExchangeBuilder.topicExchange(ITEM_TOPIC_EXCHANGE).durable(true).build();
    }

    //声明队列
    @Bean("itemQueue")
    public Queue itemQueue(){
        return QueueBuilder.durable(ITEM_QUEUE).build();
    }

    //绑定队列和交换机
    @Bean
    public Binding itemQueueExchange(@Qualifier("itemQueue") Queue queue,
                                     @Qualifier("itemTopicExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("item.#").noargs();
    }

}

消息监听处理类

@Component
public class MyListener {

    /**
     * 监听某个队列的消息
     * @param message 接收到的消息
     */
    @RabbitListener(queues = "item_queue")
    public void myListener1(String message){
        System.out.println("消费者接收到的消息为：" + message);
    }
}

测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitMQTest {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void test(){
        rabbitTemplate.convertAndSend(RabbitMQConfig.ITEM_TOPIC_EXCHANGE, "item.insert", "商品新增，routing key 为item.insert");
        rabbitTemplate.convertAndSend(RabbitMQConfig.ITEM_TOPIC_EXCHANGE, "item.update", "商品修改，routing key 为item.update");
        rabbitTemplate.convertAndSend(RabbitMQConfig.ITEM_TOPIC_EXCHANGE, "item.delete", "商品删除，routing key 为item.delete");
    }
}
