为什么我会收到 RabbitMQ 交换异常？

Question

这是我的测试队列设置，它们不正确但有效：

mq:
  username: guest
  password: guest
  host: localhost
  port: ${QA_RABBIT_LISTENER}
  ig-smev3:
    listener:
      vhost: /
      exchangeName: igSmev3Listener
      queueName: igSmev3-ListenerQueue
      routingKey: igSmev3-Listener
    producer:
      vhost: /
      exchangeName: igSmev3Producer
      queueName: igSmev3-ProducerQueue
      routingKey: igSmev3-Producer

如果我设置

vhost: /
      exchangeName: igSmev3Producer
      queueName: igSmev3ProducerQueue
      routingKey: igSmev3Producer

我会得到一个错误：

Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'type' for exchange 'igSmev3Listener' in vhost '/': received 'fanout' but current is 'direct', class-id=40, method-id=10)

怎么了？

Answer 1

inequivalent arg 'type' for exchange 'igSmev3Listener' in vhost '/': received 'fanout' but current is 'direct'

您在经纪人上已经有一个 igSmev3Listener 交易所，其类型是 fanout，但您提供相同的名称和默认类型 - direct.

考虑在开始申请之前删除该交换。

这感觉就像一个似曾相识的人，有类似的问题和类似的属性：
