Olá, pessoal.
Preciso de um método na minha classe FuncionarioDAO(estendido de uma classe genérica) que retorne uma lista através de um consulta HQL, mas só dá “java.lang.NullPointerException”;
PS: Os métodos que são estendidos do Generic estão todos ok.
O método em questão é o “listarNomes”:
package br.com.techfor.nasa.dao;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import br.com.techfor.nasa.model.Funcionario;
@Repository
public class FuncionarioDAOImpl extends GenericDAOImpl<Funcionario, Long>
implements FuncionarioDAO {
public FuncionarioDAOImpl(Class<Funcionario> classe) {
super(classe);
// TODO Auto-generated constructor stub
}
@Autowired
public FuncionarioDAOImpl(SessionFactory sessionFactory) {
this(Funcionario.class);
setSessionFactory(sessionFactory);
}
public List<Funcionario> listarNomes(String nome) {
String hql = "from Funcionario f where f.nome like '%" + nome + "%'";
return getHibernateTemplate().find(hql);
}
}
Cara, está dando erro nessa linha?
return getHibernateTemplate().find(hql);
Pode colar o stacktrace do nullpointer?
É claro, mas mudou o erro, pois mudei o método de teste.

Disfarcem… :oops: :oops:
O erro tava no applicationContext:
O id do bean tava pegando o Genérico. Agora, troquei para :
Blz cara, qualquer coisa dá um toque!
