@RabbitListener上的交换机type声明为topic时：
ERROR connection.CachingConnectionFactory:1248 - Channel shutdown: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg ‘type’ for exchange ‘lottery_delay_exchange’ in vhost ‘/’: received ‘topic’ but current is ‘‘x-delayed-message’’, class-id=40, method-id=10)

@RabbitListener上的交换机type声明为x-delayed-message时：
org.springframework.beans.factory.BeanInitializationException: Unexpected exchange type: x-delayed-message

rabbitmq版本为3.6.14，这是怎么回事啊？
