SpringBoot整合RabbitMQ出现org.springframework.amqp.AmqpException: No method found for class

@Component

@RabbitListener(queues="my_fanout")

public class Consumer {

    @RabbitHandler 

    public void process(String msg){

        System.out.println(msg);

    }

}

但是运行接收消息时，后台一直循环报错

Caused by: org.springframework.amqp.AmqpException: No method found for class [B

解决方法：
@RabbitListener(queues=”my_fanout”)不需要放在类上。直接注释在方法上就好

@Component

public class Consumer {

    @RabbitListener(queues="my_fanout")

    public void process(Message message){

        System.out.println(new String(message.getBody()));

    }

}
