Alguém poderia me ajudar com esse error no meu DAO Generico hibernate?
meu dao generico:
import org.hibernate.Session; import org.hibernate.criterion.MatchMode; import util.HibernateUtil; public abstract class AbstractDAO<T> { private Class classe; private Session session; public AbstractDAO(){ this.classe = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0]; } protected Session getSession(){ if(this.session == null || !this.session.isOpen()){ this.session = HibernateUtil.getSessionFactory().openSession(); } return this.session; } public void save(T t){ getSession().beginTransaction(); getSession().save(t); getSession().close(); } public void delete(T t){ getSession().beginTransaction(); getSession().delete(t); getSession().close(); } public void alter(T t){ getSession().beginTransaction(); getSession().update(t); getSession().close(); } public List<T> findAll(T t){ return getSession().createCriteria(this.classe).list(); } /** * Metodo responsavel por recuperar todos os objetos de uma tabela da base de dados de acordo * com o exemplo passado. * * @param filtro * @param matchMode * @param ignoreCase * @return lista */ public List<T> findByExample(T filtro, MatchMode matchMode, boolean ignoreCase){ org.hibernate.criterion.Example example = org.hibernate.criterion.Example.create(filtro); if(matchMode != null){ example = example.enableLike(matchMode); } if(ignoreCase){ example = example.ignoreCase(); } return getSession().createCriteria(this.classe).add(example).list(); } meu hibarnate util
public class HibernateUtil {
private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from hibernate.cfg.xml sessionFactory = new Configuration().configure().buildSessionFactory(); } catch (Throwable ex) { // Make sure you log the exception, as it might be swallowed System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } }
meu main:
public static void main(String[] args) { Departamento depart = new Departamento(); AbstractDAO<Departamento> padrao = new DepartamentoDAO(); padrao.findAll(depart); System.out.println(padrao); } meu error:
