Question

Je rencontre une exception ConstraintViolationException lorsque je tente de sauvegarder un objet contenant une carte @OneToMany. Hibernate semble penser que j'essaie de mettre une valeur NULL dans la liste mappée ou peut-être la placer elle-même. Le problème semble se produire de façon sporadique: avec certaines bases de données, il est facilement reproductible, mais avec d’autres, je ne peux pas le faire du tout.

Je suis un débutant à la fois aux annotations Hibernate et Hibernate, donc toute aide serait grandement appréciée.

J'ai deux classes: Camera et AlarmZone (qui étend une 3ème classe, Zone). Caméra contient notamment une liste d'identifiants d'objets AlarmZone. Voici les déclarations de classe: 

@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
{
    ...
}

Chaque fois que j'enregistre un objet, j'utilise ce que j'ai compris pour être un code de validation standard: 

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;
}

Le problème se produit lorsque je sauvegarde une AlarmZone, puis que je inscrit son identifiant dans la liste de la caméra et que je tente de sauvegarder la caméra. Pour obtenir de meilleures informations de débogage, j'ai suivi les conseils de https: //forum.hibern .org / viewtopic.php? p = 2220295 & sid = a7ccc3be32137436c8062a99c8372a9e et définir la taille de mon lot sur 0 et activer le débogage au niveau DEBUG dans log4j. Voici la trace de la pile pour l'erreur (avec les quelques lignes précédentes):

La solution

Votre code pose plusieurs problèmes:

  1. Vous avez des identifiants déclarés comme étant Serializable au lieu de long (ou Long ). Pourquoi?
  2. Vous devez mapper les occurrences de la zone (ou AlarmZone si vous le souhaitez) dans votre relation OneToMany au lieu des identifiants. Il n’est pas nécessaire d’utiliser une table intermédiaire à moins que la relation soit vraiment ManyToMany, auquel cas elle doit être mappée comme telle (une seule AlarmZone peut-elle appartenir à plus d’une caméra? Dans l’affirmative, elle est plusieurs à plusieurs).
  3. Vous avez une annotation d'héritage sur votre entité Caméra . Pourquoi? Cela fait-il partie d'une autre hiérarchie?
  4. Le "standard" " le code que vous utilisez est mauvais. La transaction doit inclure un l'unité entière de travail , pas une entité individuelle. Un rinçage explicite n'est pas nécessaire.

Exemple de mappage: 

@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;
  }
}
