导包：

     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>

配置：

#rabbitmq配置
spring.rabbitmq.host=10.0.0.19
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/

创建exchange,queue,binding

访问rabbitmq服务：http://10.0.0.1:5672,配置exchange和queue，绑定

使用代码创建，绑定

    @Test
    public void createOrDelete() {
        amqpAdmin.declareExchange(new DirectExchange("amqpadmin.direct.exchange"));
        amqpAdmin.declareQueue(new Queue("amqpadmin.direct.queue"));
        amqpAdmin.declareBinding(
                new Binding("amqpadmin.direct.queue"
                , Binding.DestinationType.QUEUE
                , "amqpadmin.direct.exchange"
                , "whu.cn"
                , null));

    }

使用：

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

    @Autowired
    private RabbitTemplate rabbitTemplate;
    
    @Test
    public void sendMsgDirect() {
        Map<String, String> map = new HashMap<>();
        map.put("code", "123");
        map.put("msg", "第一条消息");
        map.put("data", "远看一条狗");
        rabbitTemplate.convertAndSend("direct-exchange", "whu.com", map);
    }

    @Test
    public void receiveMsgDirect() {
        Object o = rabbitTemplate.receiveAndConvert("whu.com");
        System.out.println(o);
    }

    @Test
    public void sendMsgTopic() {
        Map<String, String> map = new HashMap<>();
        map.put("code", "123");
        map.put("msg", "第一条消息");
        map.put("data", "远看一条狗");
        rabbitTemplate.convertAndSend("topic-exchange", "th.cn", map);
    }

    @Test
    public void receiveTopic() {
        Object o = rabbitTemplate.receiveAndConvert("th.com");
        System.out.println(o);
    }
}
