Hibernate-validator: @NotEmpty не работает для нулевых значений

0 голосов
/ 26 октября 2009

Я аннотировал поле String тегом @NotEmpty.

Когда я пытаюсь сохранить сущность со значением этого поля "", она работает нормально. Механизм обнаруживает ошибку проверки и вызывает исключение InvalidStateException, уведомляя о проблеме.

Но когда я пытаюсь сохранить сущность со значением этого поля null, возникает исключение UndeclaredThrowableException (вызванное InvocationTargetException, вызванное свойством PropertyValueException: свойство not-null ссылается на нулевое или временное значение), поскольку система пытается обратиться к базе данных с нулевым значением в необнуляемом поле.

Вопрос очевиден: почему механизм валидации не обнаруживает эту ситуацию? Я думаю, что это должно вызвать исключение InvalidStateException вместо UndeclaredThrowableException.

Я использовал следующие библиотеки: 

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

и теперь я просто обновляюсь до 

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

Это последние стабильные выпуски.

Но он все еще не работает.

Есть идеи?

Я получил ту же ошибку, которая исправила себя, как только я сделал следующее: 

public class CustomEventListener implements PreUpdateEventListener{...}

вместо предыдущего кода, который был: 

public class CustomEventListener{..}

Прежде всего, «объединить перед сохранить» не имеет смысла. При необходимости вы можете использовать merge () вместо save (), но merge () уже возвращает постоянный экземпляр - следующее сохранение () бессмысленно.

Во-вторых, насколько я знаю, merge () не вызывает прослушиватели событий pre-insert / pre-update по умолчанию; таким образом, проверка никогда не выполняется. Вы можете обойти это, вручную указав прослушиватель для события слияния или , вручную вызывая validatior до объединения.
