Could not find result map com.youotech.tl_cons_credit_rating.entity.Result

后端报错如下：

java.lang.IllegalArgumentException: Result Maps collection does not contain value for com.youotech.tl_cons_credit_rating.entity.Result

前端调用报错如下：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

Could not find result map com.youotech.tl_cons_credit_rating.entity.Result

 

问题原因：

resources/mapper里面误将返回类型resultType错写成resultMap类型了

使用resultMap时，必须要有<resultMap></resultMap>标签指明id和返回类型以及表字段的对应关系。

如果是直接返回一个用户定义的实体类型，则要使用resultType，弄混淆就会报错。
