今天遇到一个问题，半天没看出来问题，特意记录一下

Dao

ConfigEvaluation findConfigEvaluationByEvalpecent(BigDecimal evalPercent);

Mapper.xml

        select * from Config_Evaluation      where #{evalPercent} between evalStart and evalEnd

Service

ConfigEvaluation configEvaluationByEvalpecent = configEvaluationMapperQuery.findConfigEvaluationByEvalpecent(new BigDecimal(8888));

我之前错把sql写成如下，导致半天没找到原因。所以以后遇到问题还是得仔细排查。

        select * from Config_Evaluation      where evalPercent=#{evalPercent} between evalStart and evalEnd
