Pessoal, Ola.

Sou novato em Java, preciso realizar o tratamento de erro para registros não localizados via hibernate.

Estou utilizando um dao generico, quando executo o load(id) recebo ObjectNotFoundException devido ao registro não existir no banco de dados.

alguem pode me ajudar.

Wlsilva

@SuppressWarnings(“unchecked”)

public T load (String id){

return (T) session.load(persistentClass, id);

}

try{
   obj = load("01");
   //Carregou o objeto
   //Fazer algo com o objeto carregado
}catch(ObjectNotFoundException ex){
   //Fazer alguma coisa com o registronão encontrado
}

procure mais sobre try e catch

Qual a dúvida ai? Fazer o tratamento da exception? Se for isso, aconselho dar uma lida em Exceptions, try, catch, throws e etc…

a classe está mapeada corretamente no seu cfg?

grato pela atenção, mas é o seguinte:

o codigo esta assim:

@SuppressWarnings(“unchecked”)

public T load (String id){

<a href="//logger.info">//logger.info</a>(“lendo” + persistentClass + "com id " + id );

try{

return (T) session.load(persistentClass, id);

}catch(ObjectNotFoundException ex)

{

System.out.println(“Erro Load”);

return (T) persistentClass ;

}

}

porem não esta passando pela rotina de tratamento erro.

O trecho do exception:
