針對上述日誌中產生的問題的解決方案
- 在消費者的類上面刪除掉註解
@RabbitListener(queues = OfficeQueue.OFFICE_QUEUE)
- 在消費者的方法上面加上註解
@RabbitListener(queues = OfficeQueue.OFFICE_QUEUE)
- 在消費者的方法上面去掉註解
@RabbitHandler
上面的方法處理完後又出現異常（忘記記錄）
- 總的意思是在說，消費者在隊列中獲取這條消息時，生產者那邊生產的 message 是空的;
問題排查
對服務裏面的各個模塊生產消息的地方進行代碼檢查：
- 發現有幾處生產消息的地方，message 發送出去時，內容是空的；
解決方式
- 將所有生產者 message 爲空的地方作出修改，不允許消息爲空還發出消息的情況;
本次異常引申出的一些問題
- 日誌非常非常的大，本來服務器 180G 的磁盤空間，已經被佔滿了 152G
- 由於磁盤空間越來越少，導致其他服務器再發布時，無法發佈成功
