간단한 사용자 정의 엔티티 집합 인 속성을 선택하려고하지만 애매한 예외가 발생합니다. 여기스프링 데이터 Jpa 새로운 문제 선택
public class AdminRole {
private String name;
private Set<AdminRole> adminRoles;
}
ar.adminRoles가 Set<AdminRole> adminRoles입니다 :
@Query("SELECT new com.my.package.MyModel(ar.name, ar.adminRoles) " +
" FROM AdminRole ar ")
이 내 클래스입니다. 내 생성자가 정확하며 MyModel (ar.name)을 검색하려는 경우 제대로 작동합니다. 그것은 생성자에서 SET 전달에 문제가있는 것, 당신은 그 문제를 해결하는 방법을 알고 있습니까?
