仔细看一下报错信息: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 'messageChange' in vhost '/': received 'fanout' but current is 'direct', class-id=40, method-id=10)

大概意思是交换机的类型不匹配,消费端应该收到名称为“messageChange”,类型为“fanout”的交换机发送的消息,但是当前RabbitMQ中存在的名称为“messageChange”的交换机的类型却是“direct”,所以交换机的类型不匹配。

打开RabbitMQ可以看到确实是这样:

 

目前有两种解决方式:

一、更改消费端代码中声明的交换机名称即可;

二,把RabbitMQ中的同名却不同类型的交换机删除即可;

消费端代码如下,交换机名称为“messageChange”,类型为“fanout”;
