I have to create create Criteria or Criterion on specific field myProperity (on class MyClass). I have to choose all objects that have prop = null or satisfy specific Criteria. So I should make something like:
Criteria criteria = this.sessionManager.getCurrentSession().createCriteria(MyClass.class);
specificCriteria = criteria.createCriteria('myProperity');
/* definition of specificCriteria */
Disjunction disjunction = Restrictions.disjunction();
disjunction.add(Restrictions.isNull('myProperity'));
disjunction.add(specificCriteria);
criteria.add(disjunction);
The problem is caused be the facts:
Have you any Idea how to deal with it?
You can get answer of all question here this will help you
for ex if your MyClass like
class MyClass{
private long id;
private String myProperity;
.
.
.
setter & getter
}
here you null issue is solved and this'll oring with other criterias.
Criteria criteria = session.createCriteria(MyClass.class);
Disjunction disjunction = Restrictions.disjunction();
disjunction.add(Restrictions.isNull("myProperity"));
criteria.add(disjunction);
criteria.add(Restrictions.eq("id", value));
