在Hibernate条件限制中使用所选对象

Question

I am trying to rewrite a query:

select user from UserImpl as user where user not in (:affectedPersons)

With a Hibernate Criteria as:

createCriteria(UserImpl.class, "user").add(Restrictions.not(Restrictions.in("user", affectedPersons))));

But I get Hibernate exception saying:

'user' field is not found in UserImpl entity

I understand the exception but I can't find the way how to use/specify 'user' alias of selected object to make it available in criteria restriction.

Thank you in advance.

Here You have to give the Column/field not(Restrictions.in("user"), It will search for the field user in UserImpl , which it will not find. That is why it is giving error

Criteria criteria = session.createCriteria(UserImpl.class,"user"); criteria.add(Restrictions.not(Restrictions.in("nameOfFieldInWhichYouAreStoringAffectedPersons", affectedPersons)));
