We also use hibernate & spring for that kinds of things. Here's an
example (in a class extending HibernateDaoSupport):
public List<Empleado> getObjects(Date startDate){
DetachedCriteria criteria = DetachedCriteria.forClass
(Empleado.class);
criteria.add(Restrictions.ge("desde", startDate));//desde must be
the name of the field in your Empleado object
List<Empleado> result = getHibernateTemplate().findByCriteria
(criteria);
return result;
}
That's my recommended solution in Hibernate (notice that there are no
strings [besides the name of the field of course] just dates and
Empleados ;) )
Cheers,
Salvador
