[Resolvido]Como acessar os métodos do HibernateTemplate em um DAO estendido do Generic

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);
	}
}

É claro, mas mudou o erro, pois mudei o método de teste.

Classe do teste:

package br.com.techfor.nasa.teste;

import static org.junit.Assert.assertNotNull;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import br.com.techfor.nasa.dao.FuncionarioDAOImpl;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = "applicationContext.xml")
public class TesteDAO {

	private FuncionarioDAOImpl funcionarioDAOImpl;

	@Autowired
	public void setFuncionarioDAOImpl(FuncionarioDAOImpl funcionarioDAOImpl) {
		this.funcionarioDAOImpl = funcionarioDAOImpl;
	}

	@Test
	public void getAllTest() {
		assertNotNull(funcionarioDAOImpl);
		assertNotNull(funcionarioDAOImpl.listarNomes("SHAZAN"));

	}

}
