jpa로지도 요소 삭제하기

지도에서 영구 요소를 제거 할 수있는 일을 지금 알아 내려고하고 있습니다. 비슷한 문제가있는 스레드를 찾았지만 아무도 나를 마침내 도울 수 없었습니다. 모든 것이 잘 작동하고, 요소를 추가하고 유지하며, 요소를 편집하고 업데이트하는 등의 작업을 수행합니다. 요소 삭제를 제외합니다. 나는 평일마다 5 개의지도로 시간 계획을 세우고있다.jpa로지도 요소 삭제하기

@Entity 
public class Schedule extends JPAEntity implements Serializable {

    public boolean removeSubject(final int index, final SchoolSubject oldSubject) { 
     final String day = oldSubject.getWeekday(); 

     switch (day) { 
     case "Montag": 
      return monday.remove(index, oldSubject); 
     case "Dienstag": 
      return tuesday.remove(index, oldSubject); 
     case "Mittwoch": 
      return wednesday.remove(index, oldSubject); 
     case "Donnerstag": 
      return thursday.remove(index, oldSubject);

SchoolSubject :

이

@Entity 
public class SchoolSubject extends JPAEntity implements Serializable { 

    private static final long serialVersionUID = -3554577133392512324L; 

    @Column(nullable = false) 
    private String name; 

    @Basic 
    @Column(nullable = false) 
    private int hourTime; 

    @ManyToOne(optional = false) 
    private Schedule schedule;

JPAEntity :

@MappedSuperclass 
@EntityListeners(JPAEntityListener.class) 
public class JPAEntity { 


    @Id 
    @GeneratedValue 
    private Long id;

그래서 다른 로직 클래스 내 삭제-방법이 여기에 코드의 핵심 부분은

가 일정하다 다음 :

@Override 
    public void removeSubject(User user, Schedule schedule, SchoolSubject oldSubject) { 
     if (schedule.removeSubject(oldSubject.getHourTime() - 1, oldSubject)) { 
      schoolSubjectDAO.remove(oldSubject); 
     } 

     scheduleDAO.update(schedule); 
     try { 
      userDAO.update(user); 
     } catch (final DuplicateUniqueFieldException e) { 
      throw new UnexpectedUniqueViolationException(e); 
     } 
    }

메소드를 디버깅하고 있는데, 일정에서 요소를 성공적으로 제거하고 있습니다. 그러나 scheduleDAO.update(schedule)은 완전히 작동하지 않는 것 같습니다. 내가 말했듯이, 모든 다른

내가 다음 업데이트는 단방향 관계로 변경하고, SchoolSubject.schedule 필드를 제거, 지금 제안을 crizzis

완벽하게 작동합니다.

업데이트 일정 클래스 : (전 일) 주제를 추가 할 때
@Entity public class Schedule extends JPAEntity implements Serializable { /** * Die eindeutige SerialisierungsID. */ private static final long serialVersionUID = -3554837193392512324L; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @MapKey(name = "hourTime") private Map<Integer, SchoolSubject> monday; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @MapKey(name = "hourTime") private Map<Integer, SchoolSubject> tuesday; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @MapKey(name = "hourTime") private Map<Integer, SchoolSubject> wednesday; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @MapKey(name = "hourTime") private Map<Integer, SchoolSubject> thursday; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @MapKey(name = "hourTime") private Map<Integer, SchoolSubject> friday;

그러나이와
내가 새로운 오류가 발생했습니다. 가산 동작은 다음과 같은 : 당신은 그런 mappedBy를 다시 사용할 수 없습니다

removeSubject impl을 추가 할 수 있습니까? 또한 업데이트 전에 병합을 수행합니까? –

그래, 클래스 메서드를 사용하여 클래스를 업데이트했지만 디버깅하는 동안 그 방법에 문제가없는 것 같았다. 엔티티 맵에서 오브젝트를 성공적으로 제거하고있었습니다. 병합은 실제로 javax.persistence.EntityManager'의 merge() 메소드 인 scheduleDAO.update (schedule)에 의해 수행됩니다. 요소를 추가하고 scheduleDAO.update (schedule)를 수행 할 때 모든 것이 잘 작동합니다. – Noli

보았습니다. 어떤 퍼시스턴스 공급자를 사용하고 있습니까? 버전은 무엇입니까? –
