Hibernate ConstraintViolationException w tabeli join

2009-10-23 17 views

Podczas próby zapisania obiektu z mapą @OneToMany uruchamiam wyjątek ConstraintViolationException. Hibernate albo wydaje się myśleć, że próbuję umieścić NULL na mapowanej liście lub może to być umieszczenie jej tam. Problem wydaje się zdarzać sporadycznie: w przypadku niektórych baz danych jest łatwo powtarzalny, ale z innymi nie mogę tego zrobić w ogóle.Hibernate ConstraintViolationException w tabeli join

Jestem rodzajem nowicjusza na obu adnotacjach Hibernate i Hibernate, więc każda pomoc w ogóle byłaby doceniana.

Mam dwie klasy: Camera i AlarmZone (która rozszerza trzecią klasę, Zone). Aparat zawiera między innymi listę identyfikatorów obiektów AlarmZone. Oto deklaracje klasy:

@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 
{ 
    ... 
}

Ilekroć zapisać obiekt, używam tego, co rozumiem, aby być boilerplate popełnić Kod:

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; 
}

Problem zdarza się kiedy zapisać AlarmZone, a następnie umieścić swój identyfikator do listę kamer i spróbuj zapisać aparat. Aby uzyskać lepsze informacje na temat debugowania, postępowałem zgodnie z radą https://forum.hibernate.org/viewtopic.php?p=2220295&sid=a7ccc3be32137436c8062a99c8372a9e i ustawiłem rozmiar wsadu na 0 i włączono debugowanie poziomu DEBUG w log4j. Oto ślad stosu do błędu (wraz z poprzednich kilku liniach):

Istnieje kilka problemów z kodem:

  1. Masz identyfikatory zadeklarowane jako SERIALIZABLE zamiast zwykłego long (lub Long). Czemu?
  2. Powinieneś odwzorować rzeczywiste Zone (lub AlarmZone, jeśli chcesz) instancje w relacji OneToMany zamiast identyfikatorów. Nie ma potrzeby korzystania z pośredniej tabeli, chyba że związek jest naprawdę ManyToMany, w którym to przypadku powinien być mapowany jako taki (czy pojedynczy AlarmZone może należeć do więcej niż jednej kamery? Jeśli tak, to jest wiele-do-wielu).
  3. Masz adnotację dziedziczenia na jednostce Camera. Czemu? Czy jest częścią innej hierarchii?
  4. Kod "podstawowa", którego używasz jest zły. Transakcja powinna obejmować jednostkę entire unit of work, a nie indywidualną. Wyraźne spłukiwanie jest niepotrzebne.

mapowanie Próbka:

@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; 
    } 
}

Dzięki za porady.Są bardzo doceniane. Zdecydowanie zgadzam się, że posiadanie listy rzeczywistych obiektów AlarmZone jest drogą do zrobienia, ale nie mam wystarczająco dużo czasu, aby wprowadzić wymagane zmiany do bazy kodów. Czy masz pojęcie, co może być przyczyną wyjątku na wstawieniu tabeli łączenia? – Seth

Nie mam zamiaru być o tym palantem, ale jeśli nie masz czasu, aby zrobić to poprawnie teraz, jak znajdziesz czas później (kiedy zbudujesz więcej rzeczy na ten temat)? Problem z ids AlarmZone jest taki, że Long NIE jest bytem; NIE możesz mapować identyfikatorów jako @OneToMany. Jedynym sposobem na ich odwzorowanie jest użycie opcji @CollectionOfElements - patrz rozdział 2.4.2.2.5 dokumentacji adnotacji Hibernate dla przykładu. – ChssPly76

Niestety, są okoliczności, na które nie mam wpływu, które uniemożliwiają mi wykonanie tego poprawnie teraz (konkretnie, refaktoryzacja kodu, aby zamknąć pełną jednostkę pracy i zmianę klasy Camera tak, aby faktyczne alarmy zajęły znacznie więcej czasu niż ja. Ten zły kod jest rozrzucany w całej aplikacji). – Seth
