Ich bin in eine ConstraintViolationException, wenn ich versuche, Sie zu speichern ein Objekt eine @OneToMany-Karte in es.Hibernate entweder scheint zu denken, dass ich bin versucht zu setzen eine NULL in der zugeordneten Liste oder es kann sein, setzen Sie sich.Das problem scheint zu passieren sporadisch:mit einigen Datenbanken ist es leicht reproduzierbar, aber mit anderen kann ich es nicht bekommen zu sein.
Ich bin eine Art Neuling in beide Hibernate, Hibernate Annotationen, so dass jede Hilfe wäre sehr geschätzt werden.
Ich habe zwei Klassen:Kamera und AlarmZone (der sich eine 3. Klasse, Zone).Unter anderem, Kamera enthält eine Liste von IDs der AlarmZone Objekte.Hier ist die Klasse Erklärungen:
@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
{
...
}
Immer wenn ich speichern eines Objekts, die ich verwenden, was ich verstehe, werden Sie boilerplate-commit-code:
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;
}
Das problem tritt auf, wenn ich speichern einer AlarmZone, dann legen Sie dessen ID in der Kamera-Liste und speichern Sie die Kamera.Um besser zu Debuggen, info, folgte ich dem Rat aus https://forum.hibernate.org/viewtopic.php?p=2220295&sid=a7ccc3be32137436c8062a99c8372a9e und meine batch-Größe auf 0 ein und aktiviert den DEBUG-level debugging in log4j.Hier ist der stack-trace des Fehlers (zusammen mit dem vorangegangenen paar Zeilen):

Lösung
Es gibt mehrere Probleme mit Ihrem code:
- Sie haben ids deklariert als Serialisierbar anstelle von normalem
long(oderLong).Warum? - Sollten Sie die Karte tatsächlichen
Zone(oderAlarmZonewenn Sie möchten) - Instanzen in Ihrer OneToMany-Beziehung anstelle von ids.Es gibt keine Notwendigkeit für zwischentisch, es sei denn, die Beziehung ist wirklich ManyToMany in diesem Fall sollte es zugeordnet werden, als solche (kann eine einzelne AlarmZone gehören mehr als eine Kamera?Wenn ja, ist es, viele-zu-viele). - Sie haben die Vererbung Anmerkungen auf Ihrer
CameraEinheit.Warum?Ist es Teil einer anderen Hierarchie? - Die "boilerplate" - code, die Sie verwenden, ist schlecht.Transaktion schließen ein gesamte Einheit von der Arbeit, nicht einzelne Entität.Explizite Spülung unnötig ist.
Sample-mapping:
@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;
}
}
