문제

@onetomany 맵이있는 객체를 저장하려고 할 때 제약 ViolationException으로 실행 중입니다. 최대 절전 모드는 내가 매핑 된 목록에 널을 넣으려고한다고 생각하는 것 같습니다. 문제는 산발적으로 발생하는 것처럼 보입니다. 일부 데이터베이스를 사용하면 쉽게 재현 할 수 있지만 다른 데이터베이스를 사용하면 전혀 발생할 수 없습니다.

나는 최대 절전 모드 및 최대 절전 모드 주석 모두에 일종의 초보자이므로 도움이 전혀 감사 할 것입니다.

카메라와 알람 존 (3 학년, 영역을 연장)의 두 가지 수업이 있습니다. 무엇보다도 카메라에는 알람 존 객체의 ID 목록이 포함되어 있습니다. 수업 선언은 다음과 같습니다.

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "cameras")
public class Camera
{
    private Serializable id;

    private List<Serializable> alarm_zones = new ArrayList<Serializable>();

    ...

    @Id(generate = GeneratorType.SEQUENCE)
    @Type(type = "java.lang.Long")
    public java.io.Serializable getId()
    {
        return this.id;
    }

    public void setId(java.io.Serializable id)
    {
        this.id = id;
    }

    @OneToMany(targetEntity = java.lang.Long.class, fetch = FetchType.EAGER)
    @JoinTable(table = @Table(name = "cameraalarmzones"))
    public List<Serializable> getAlarmZones()
    {
        return alarm_zones;
    }

    public void setAlarmZones(List<Serializable> alarm_zones)
    {
        this.alarm_zones = alarm_zones;
    }

    ...
}

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "zones")
public class Zone
{
    private Serializable id;

    ...

    @Id(generate = GeneratorType.SEQUENCE)
    @Type(type = "java.lang.Long")
    public java.io.Serializable getId()
    {
        return this.id;
    }

    public void setId(java.io.Serializable id)
    {
        this.id = id;
    }
}

@Entity
@Table(name = "alarmzones")
public class AlarmZone extends Zone
{
    ...
}

객체를 저장할 때마다, 나는 내가 이해하는 것을 보일러 플레이트 커밋 코드로 사용합니다.

public Persistable makePersistent(Object entity)
{
    try
    {
        Hibernate.getSession().beginTransaction();
        Hibernate.getSession().saveOrUpdate(entity);
        Hibernate.getSession().flush();
        Hibernate.getSession().getTransaction().commit();
    } catch (RuntimeException e)
    {
        Hibernate.getSession().getTransaction().rollback();
        logger.error("makePersistent(" + entity.getClass().getSimpleName()
                + ")", e);
    }
    return entity;
}

알람 존을 저장 한 다음 ID를 카메라 목록에 넣고 카메라를 저장할 때 문제가 발생합니다. 더 나은 디버그 정보를 얻으려면 조언을 따랐습니다. https://forum.hibernate.org/viewtopic.php?p=2220295&sid=a7ccc3be32137436c8062a99c8372a9e 배치 크기를 0으로 설정하고 Log4J에서 디버그 레벨 디버깅을 켰습니다. 오류의 스택 추적은 다음과 같습니다 (이전 몇 줄과 함께) :

해결책

코드에는 몇 가지 문제가 있습니다.

  1. IDS는 평범한 대신 직렬화 가능한 것으로 선언했습니다 long (또는 Long). 왜요?
  2. 당신은 실제를 맵핑해야합니다 Zone (또는 AlarmZone 원하는 경우) ID 대신 onetomany 관계의 인스턴스. 관계가 실제로 많은 사람이 아닌 한 중간 테이블이 필요하지 않습니다.이 경우 단일 알람 존은 하나 이상의 카메라에 속할 수 있습니까? 그렇다면, 다수입니다).
  3. 당신은 당신의 상속 주석이 있습니다 Camera 실재. 왜요? 다른 계층의 일부입니까?
  4. 사용중인 "보일러 플레이트"코드는 나쁘다. 거래는 an을 둘러싸고 있어야합니다 전체 작업 단위, 개별 실체가 아닙니다. 명백한 플러싱은 불필요합니다.

샘플 매핑 :

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "cameras")
public class Camera {
    private long id;
    private List<AlarmZone> alarm_zones = new ArrayList<AlarmZone>();

    @SequenceGenerator(name="Camera_Gen", sequenceName="cameras_seq")
    @Id @GeneratedValue(generator="Camera_Gen")    
    public long getId() {
        return this.id;
    }

    @OneToMany(mappedBy="camera") // this maps a bi-directional relationship
    public List<AlarmZone> getAlarmZones() {
        return alarm_zones;
    }

    ...
}

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "zones")
public class Zone {
  // same deal as above
  ...
}

@Entity
@Table(name = "alarmzones")
public class AlarmZone extends Zone {
  private Camera camera;

  @ManyToOne
  public Camera getCamera() {
    return this.camera;
  }
}
