Hibernate-validator: @NotEmpty no funciona para valores nulos

Pregunta

He anotado un campo String con la etiqueta @NotEmpty.

Cuando trato de persistir la entidad con el valor de este archivo " " ;, funciona bien. El mecanismo detecta el error de validación y genera una excepción InvalidStateException que notifica el problema.

Pero cuando trato de persistir la entidad con el valor de este campo nulo, se genera una excepción UndeclaredThrowableException (causada por InvocationTargetException, causada por PropertyValueException: la propiedad no nula hace referencia a un valor nulo o transitorio) porque el sistema intenta alcanzar la base de datos con valor nulo en un campo no anulable.

La pregunta es obvia: ¿por qué el mecanismo de validación no detecta esta situación? Creo que debería generar una excepción InvalidStateException en lugar de una UndeclaredThrowableException.

Estaba usando las siguientes bibliotecas:

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

y ahora acabo de actualizar a

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

Estas son las últimas versiones estables.

Pero todavía no funciona.

¿Alguna idea?

Plantea el siguiente error:

<*>

Gracias de antemano.

Solución

En primer lugar, " fusionar antes guardar " no tiene sentido Puede usar merge () en lugar de save () cuando sea apropiado, pero merge () ya devuelve una instancia persistente; el siguiente save () no tiene sentido.

En segundo lugar, merge () no invoca oyentes de eventos de preinserción / preactualización de forma predeterminada hasta donde yo sé; por lo tanto, la validación nunca se realiza. Puede solucionar esto con especificando manualmente el escucha para el evento de fusión o invocando manualmente validatior antes de la fusión.

Otros consejos

Recibí el mismo error que se solucionó una vez que hice lo siguiente:

public class CustomEventListener implements PreUpdateEventListener{...}

en lugar del código anterior que era:

public class CustomEventListener{..}
