Consegui pessoal conforme o link abaixo…

http://forum.springframework.org/showthread.php?t=46600

Agora surgiu uma coisa. Na minha classe Action eu devo chamar meus metodos de persistencia atraves da minha interface de servico criada. Mas ele acusa que essa classe esta fazendo referencia nula…

java.lang.NullPointerException

	org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:75)

Por favor analisem minha classe Action para eu ver o erro…

public class UsuarioDAOHibernate extends GenericHibernateDAO<Usuario, Long>
		implements UsuarioDAO {

	private SessionFactory sessionFactory;

	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

	public Usuario consultaLoginSenha(String codigo, String senha) {
		Usuario usuario = new Usuario();

		Query query = this.sessionFactory
				.getCurrentSession()
				.createQuery(
						"from br.com.MGFSuporte.DAO.Usuario as U Where U.codigo like ? and U.senha like ?");
		query.setString(0, codigo);
		query.setString(1, senha);
		usuario = (Usuario) query.uniqueResult();

		return usuario;

	}

}
public interface UsuarioService {

	Usuario consultaLoginSenha(String codigo, String senha);
}
public class UsuarioServiceImpl implements UsuarioService {

	private UsuarioDAOHibernate usuarioDAO;
	
	
	public void setUsuarioDAO(UsuarioDAOHibernate usuarioDAO) {
		this.usuarioDAO = usuarioDAO;
	}

	@Transactional(readOnly = true, propagation = Propagation.REQUIRES_NEW)
	public Usuario consultaLoginSenha(String codigo, String senha) {
		
		return this.usuarioDAO.consultaLoginSenha(codigo, senha);
	}

}

Action:


public class VerificaUsuarioAction extends Action {

	private UsuarioService usuarioService;

	public void setUsuarioService(UsuarioService usuarioService) {
		this.usuarioService = usuarioService;
	}

	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		
		
		ActionErrors errors = new ActionErrors();
		DynaValidatorForm dyna = (DynaValidatorForm) form;
		Usuario usuario = new Usuario();
		usuario = usuarioService.consultaLoginSenha(dyna.getString("codigo"),
		dyna.getString("senha"));

Obrigado…
