Yes i did it...
this is DAO and impl
public interface Dao<T extends DomainObject> {
@Transactional
void delete(T o);
T load(long id);
@Transactional
void save(T o);
@Transactional
List<T> findAll();
int countAll();
}
and the implemetation is
public abstract class AbstractHibernateDaoImpl<T extends DomainObject>
implements Dao<T> {
private Class<T> domainClass;
private SessionFactory sf;
public AbstractHibernateDaoImpl(Class<T> domainClass) {
this.domainClass = domainClass;
}
public SessionFactory getSessionFactory() {
return sf;
}
public void setSessionFactory(SessionFactory sf) {
this.sf = sf;
}
public void delete(T object) {
getSession().delete(object);
}
@SuppressWarnings("unchecked")
public T load(long id) {
return (T) getSession().get(domainClass, id);
}
public void save(T object) {
getSession().saveOrUpdate(object);
}
@SuppressWarnings("unchecked")
public List<T> findAll() {
Criteria criteria = getSession().createCriteria(domainClass);
return (List<T>) criteria.list();
}
public int countAll() {
Criteria criteria = getSession().createCriteria(domainClass);
criteria.setProjection(Projections.rowCount());
return (Integer) criteria.uniqueResult();
}
public Session getSession() {
// presumes a current session, which we have through the
// OpenSessionInViewFilter; doesn't work without that
return sf.getCurrentSession();
}
}
