Hibernate-Validator: @NotEmpty funktioniert nicht für NULL-Werte

Question

Ich habe ein String-Feld mit @NotEmpty Tag kommentiert.

Wenn ich versuche, die Einheit bestehen bleiben mit diesem Wert der eingereichten „“, es funktioniert gut. Mechanismus erkennt den Validierungsfehler und wirft eine InvalidStateException Ausnahme, das Problem zu informieren.

Aber wenn ich versuche, die Einheit bestehen bleibe mit diesem Wert null Feld, ein UndeclaredThrowableException (verursacht durch InvocationTargetException, verursacht durch PropertyValueException: nicht-null-Eigenschaft verweist auf eine Null oder transienten Wert) Exception ausgelöst wird, weil das System versucht, die Datenbank zu treffen mit null-Wert auf einem nicht-Nullable-Bereich.

Die Frage ist offensichtlich: warum Validierungsmechanismus hat diese Situation nicht erkennen? Ich denke, es sollte eine InvalidStateException Ausnahme anstelle eines UndeclaredThrowableException erhöhen.

Ich wurde mit den folgenden Bibliotheken:

  - hibernate-annotations 3.3.1.GA
  - hibernate-validator 3.0.0.ga
  - hibernate-core 3.2.6ga

und jetzt habe ich ein Upgrade nur auf

  - hibernate-annotations 3.4.0.GA
  - hibernate-validator 3.1.0.GA
  - hibernate-core 3.3.2

Dies sind die neuesten stabilen Versionen.

Aber es immer noch nicht funktioniert.

Jede Idee?

Vielen Dank im Voraus.

Answer 1

Zu allererst "merge vor speichern" ist nicht sinnvoll. Sie können Druck verwenden () anstelle von save (), wenn angemessen, aber fusionieren () bereits wieder eine persistente Instanz -. Die folgenden save () ist sinnlos

Zum anderen fusionieren () pre-insert / Hörer vor Aktualisierung Ereignis nicht standardmäßig aufrufen, soweit ich weiß; so Validierung wird nie ausgeführt. Sie können manuell angeben Hörer für merge Ereignis oder manuell aufrufen validatior vor dem Zusammenführen.

Answer 2

Ich habe den gleichen Fehler, die selbst festgelegt, sobald ich die folgende tat:

public class CustomEventListener implements PreUpdateEventListener{...}

anstelle des früheren Code, war:

public class CustomEventListener{..}
