1、核心的启动器包

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

2、配置 yml

spring:
  rabbitmq:
    host: 192.168.0.103
    username: guest
    password: guest
    virtual-host: /

3、消费端监听器对象及Rabbitmq的注解

@Component
public class Listener {

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "spring.test.queue", durable = "true"),
            exchange = @Exchange(
                    value = "spring.test.exchange",
                    ignoreDeclarationExceptions = "true",
                    type = ExchangeTypes.TOPIC
            ),
            key = {"#.#"}))
    public void listen(String msg){
        System.out.println("接收到消息：" + msg);
    }
}

4、生产方同样上面导依赖和yml配置，在需要发消息的时候注入AmqpTemplate使用

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class MqDemo {

    @Autowired
    private AmqpTemplate amqpTemplate;

    @Test
    public void testSend() throws InterruptedException {
        String msg = "hello, Spring boot amqp";
        this.amqpTemplate.convertAndSend("spring.test.exchange","a.b", msg);
        // 等待10秒后再结束
        Thread.sleep(10000);
    }
}

消费方消费方法里面有异常了抛出，这样出了异常消息不会被消费丢失，而是退回消息中间件queue中
