Abrufen des aktuellen angemeldeten Benutzers in JHipster

Question

Ich baue eine Zhipster-Anwendung. und ich versuche, eine Liste von Objekten basierend auf dem aktuell angemeldeten Benutzer zu erhalten. Es gibt ein paar einfache Beispiele online wie jhipster blog demo, die beschreiben, wie man die Blogs des aktuellen Benutzers vom aktuell angemeldeten Benutzer erhält - und ich wollte dies nachahmen. In der Demo gibt isa Repo-Methode:

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

Ich habe versucht, dies mit dem folgenden nachzuahmen:

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

aber meine IDE führt diesen Fehler:

nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List com.thefitnation.repository.WorkoutTemplateRepository.findByUserIsCurrentUser()!

Ich bin nicht zu vertraut mit Hibernate-Abfragen, aber der Parameter scheint in meiner IDE fehlerhaft zu sein. Muss der Parameter am Ende irgendwo konfiguriert werden? Ich verwende plain jhipster 4 aus der Box mit DTO-Objekten.

hier sind die zuständigen Stellen:

Sie können die aktuelle l erhalten Ogged in Benutzer-ID von SecurityUtils. SecurityUtils.getCurrentUserLogin() gibt Ihnen die Anmeldung des aktuell angemeldeten Benutzers. Verwenden Sie diese Anmeldung, um die Benutzerentität aus db abzurufen. (findOneByLogin)
