Delete a record using Spring data jpa - rest

Question

I have an entity 'Competence', this entity has OneToMany relation with two other entities : CandidatCompetence and OffreCompetence, and a ManyToOne relation with GroupCompetence.
And I have a rest delete service with will take the id of a Competence entity as following :
#Secured("ROLE_ADMIN")
#RequestMapping(value="/competences/{id}",method= RequestMethod.DELETE)
public void deleteCompetence(#PathVariable Long id) {
competenceMetier.deleteCompetence(id);
}
Then the deleteCompetence function will call a delete function from the Competence Repository which extends JpaRepository<Competence, Long> as following :
public void deleteCompetence(Long id) {
competenceRepository.delete(id);
}
The problem is that when I call the rest delete method, I get 200 as an http response, but nothing in the body, the same for the log I can't see the DELETE sql query anywhere, and the entity still exists in the database.
here are my entities :
Competence :

You should annotate your Service Method deleteCompetence with #Transactional.
