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
[]'s
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){
//logger.info(“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.
