我正在构建一个jhipster应用程序。我试图根据当前登录的用户获取对象列表。在线上有一些简单的示例，例如jhipster博客演示，描述了如何通过当前登录用户获取当前用户的博客，而我想对此进行模仿。在演示中，有一个repo方法：

@Query("select blog from Blog blog where blog.user.login = ?#{principal.username}")
List<Blog> findByUserIsCurrentUser();

我试图用以下方法来模仿：

@Query("select userWorkoutTemplate from WorkoutTemplate workoutTemplate where workoutTemplate.userDemographic.user.login = ?#{principal.username}")
List<WorkoutTemplateDTO> findByUserIsCurrentUser();

但是我的IDE抛出此错误：

嵌套异常为java.lang.IllegalArgumentException：方法公共抽象java.util.List
com.thefitnation.repository.WorkoutTemplateRepository.findByUserIsCurrentUser（）的查询验证失败！

我对hibernate查询不太熟悉，但是该参数在我的IDE中似乎有误。最后是否需要在某处配置参数？我使用DTO对象开箱即用的普通jhipster 4。

以下是相关实体：
