JSON parse error: Cannot deserialize instance of `cn.bywin.pcldata.common.base.model.quality.RuleConfigDo` out of START_ARRAY token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `cn.bywin.pcldata.common.base.model.quality.RuleConfigDo` out of START_ARRAY token\n at [Source: (PushbackInputStream); line: 1, column: 1]

連續遇到了兩次，指不定以后還會遇到，先隨筆記下來

JSON解析錯誤，嘗試下查看前端返回的值，本次遇到的是[{dataList}]和不需要[]的{dataList}，以數組的形式和以對象的形式

在重構原本項目時，沒有太過深入查看這一部分，容易在一些返回的情況中沒有及時和前端溝通拖慢進度
