app後端服務NoSuchMethodError産生原因分析

1.錯誤日志：

2.關鍵錯誤代碼：java.lang.NoSuchMethodError: com.sfAPI.api.dianjiang.service.DJOrderService.listResponse(Ljava\/util\/ArrayList;)Lcom\/sfAPI\/api\/response\/common\/ListResponse。

分析：找不到DJOrderService類中 ListResponse listResponse(ArrayList list);方法。原因：修改了DJOrderService父類listResponse方法參數ArrayList為List，Build Artifacts後，隻把DJOrderService父類的class檔案更新到伺服器中，而DJOrderService類生成的新的class檔案沒有更新到伺服器中。

3.注意：修改父類方法參數類型，要考慮子類調用該方法産生的影響。
