錯誤收集
1. 沒有對應的交換機在“/”這個虛擬機下
channel error; protocol method: #method<channel.close>(reply-code=404, reply-text=NOT_FOUND - no exchange ‘wujianqinjian_rabbitmq_publish’ in vhost ‘/’, class-id=50, method-id=20)
2. 已經聲明的隊列，修改代碼重新運行，會報錯
重新運行就會報這樣的錯！
channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg ‘durable’ for queue ‘wujianqinjian_queue_hello’ in vhost ‘/’: received ‘true’ but current is ‘false’, class-id=50, method-id=10)
