SqlResultSetMapping未知映射错误

标签： spring-boot spring-data-jpa hibernate-mapping java-ee-8 sqlresultsetmapping

我正在使用Spring Boot Rest API，并且我早些时候问过一个有关将pojo类映射到结果集的问题 Could not locate appropriate constructor on class .....

我得到了有效的答案，但是当我仅使用一个实体类和一个SqlResultSetMapping文件时。

我的StackTrace：

我的问题是

我有几个实体，例如成员，用户，课程，并且我为每个类设计了一个SqlResultSetMapping文件。但是当我测试我的API时，只有Member类获得正确的响应和映射，用户实体服务实现返回未知的SqlResultSetMapping [UserMapping] ...
