故障分析及解決過程
問題的關鍵是:"Table 'credittrans.tp_trade_order' doesn't exist" ,查找數據庫會發現,[credittrans]庫下面沒有[tp_trade_order]這張表,從而排查到是數據源配置錯誤,使用的默認數據源進行的查詢
關於多數據源可以查看:
尋找風口的豬:
mybatis用spring的動態數據源實現讀寫分離
以及
使用springboot + druid + mybatisplus完成多數據源配置
如何配置Springboot多數據源
總結
遇到這樣的問題,還是需要理解清楚,多數據源的原理.大致實現過程,才更容易排查問題
