Spring Data JPA Hibernate viele zu viele Kaskade löschen

mit Spring-Boot 1.4.0 und MySQL 5.7Spring Data JPA Hibernate viele zu viele Kaskade löschen

Ich habe zwei Tisch und es ist unidirektional @ManyToMany, aber die Eltern-Seite in der Rolle, ich will die Erlaubnis Hibernate löschen wird es sich selbst und den Link-Tabellensatz automatische löschen:

  • Permission

    @Entity 
public class Permission { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private Long id; 

    @Column(unique = true) 
    private String name; 

    //...Getter and Setter 
}

  • Rolle

    @Entity 
public class Role { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private Long id; 

    @Column(unique = true) 
    private String name; 

    @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL) 
    private final Collection<Permission> allowedPermissions = new ArrayList<>(); 

    //...Getter and Setter 
}

Aber wenn versuchen, die Permission Datensatz löschen. Der ERROR sagt mir "Kann eine Elternzeile nicht löschen oder aktualisieren: Eine Fremdschlüsselbedingung scheitert".

Ich legte die Cascade = CascadeType.ALL in Rolle.

Wie es zu beheben?

Ich will, wenn die Erlaubnis löschen, die Link-Tabelle wird alle Link der Erlaubnis entfernen.

Soweit ich verstehe, haben Sie eine Beziehung zwischen Rolle und Berechtigung als ManyToMany. Sie haben sich also der Tabelle angeschlossen (übrigens wie @Moshe angegeben hat, ich konnte Ihre JoinTable Annotation auch nicht sehen). Wenn Sie die Berechtigung löschen wollen, wollen Sie sie auch aus der Tabelle löschen, aber Sie wollen keine Rolle löschen, oder? –

Sie bekommen diese Ausnahme, weil Sie versuchen, einen Permission Datensatz auf der Permission Tabelle zu löschen, aber Sie haben nicht vor, dass die passenden Datensatz auf den Tisch kommen gelöscht.

Also, sagen wir auf Permission Tabelle Sie haben einen Datensatz mit dem Primärschlüssel von 203, müssen Sie einen Datensatz mit einem Fehlerschlüssel von 203 auf der Join-Tabelle löschen.

Übrigens, wo ist Ihre @JoinTable Annotation? Ich kann es in deinem Code nicht sehen.

Die Lösung für dieses Problem nur ist erlaubt, so dass die besitzende Einheit (mit unidirektionalen Vereinigung Sie, welche Unternehmen wird sein, den Besitz Einheit wählen).

die auf Permission bedeutet, dass Sie die verwenden müssen:

@ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)

die CascadeType.ALL (CascadeType.ALL umfasst CascadeType.REMOVE) auf Join-Tabelle alle entsprechenden Aufzeichnungen zu löschen kümmern, bevor die Aufzeichnung aus dem Besitz Einheit zu löschen.
