Hibernate-validador: @NotEmpty não funciona para valores nulos

Question

Eu tenho anotado um campo String com @NotEmpty tag.

Quando tento persistir a entidade com este valor arquivados "", ele funciona bem. Mecanismo detecta o erro de validação e levanta uma exceção InvalidStateException notificando a questão.

Mas quando eu tento a persistir a entidade com nulo valor deste campo, uma UndeclaredThrowableException (causada por InvocationTargetException, causada por PropertyValueException: não nulos referências de propriedade de um nulo ou valor transitória) exceção é levantada porque o sistema está a tentar bater o banco de dados com valor nulo em um campo não nulo.

A pergunta é óbvia: por mecanismo de validação não detectar esta situação? Eu acho que deve gerar uma exceção InvalidStateException em vez de um UndeclaredThrowableException.

Eu estava usando as seguintes bibliotecas:

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

e agora eu só atualizar para

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

Estas são as últimas versões estáveis.

Mas ainda não está funcionando.

Qualquer idéia?

Agradecemos antecipadamente.

Answer 1

Em primeiro lugar, "merge antes Salvar" não faz sentido. Você pode usar merge () em vez de save () quando apropriado, mas merge () já retorna uma instância persistente -. A seguinte save () é inútil

Em segundo lugar, merge () não invoca pré-insert / pré-atualização evento ouvintes por padrão, tanto quanto eu sei; assim validação nunca é executada. Você pode contornar isso, manualmente especificando ouvinte para o evento fusão ou manualmente invocação validatior antes da fusão.

Answer 2

Eu tenho o mesmo erro que se fixada uma vez eu fiz o seguinte:

public class CustomEventListener implements PreUpdateEventListener{...}

em vez do código anterior, que foi:

public class CustomEventListener{..}
