JPA Criteria API persistent field IN expression using list of entities

Question

I'm trying something similar to this question posted before:

JPA Criteria API IN expression Parameter list

However, I'm trying to use a list of entities instead of a list of Longs (PKs), like:

public List<Task> generateFilteredQuery( List<User> filterUsers )
{
    CriteriaBuilder cb = this.em.getCriteriaBuilder();
    CriteriaQuery<Task> criteriaQuery = cb.createQuery( Task.class );
    Root<Task> root = criteriaQuery.from( Task.class );

    criteriaQuery.select( root ).where( root.get( "owner" ).in( filterUsers ) );

    return this.em.createQuery( criteriaQuery ).getResultList();
}

Please assume this.em to be of type EntityManager . The Task entity has an associated owner, mapped like this:

@Entity
@Table( name = "TASKS" )
public class Task implements Serializable
{
        ...

        @ManyToOne( fetch = FetchType.EAGER )
        @JoinColumn( name = "OWNER_USER_ID", referencedColumnName = "USER_ID" )
        private User owner;

        ...
}

I know I have used something similar from JPQL before, but I don't see how it is done using the Criteria API.

Using the above code causes a DB exception to ocurr:

The problem with this basically is the part ... AND (t1.OWNER_USER_ID IN (?))) ... as this assumes some kind of List to be used. This is not desired.

I remember having done something like that with JPQL and Hibernate as a JPA provider before, now here's the question.

Q :

Is there a Criteria equivalent for JPQL ... WHERE task.owner IN :filterUsers , where :filterUsers is a standard named paramater using query.setParameter( "filterUsers", filterUsers ) and the latter being declared as List<User> filterUsers = ... ? If so, how's it done?

PS: Sorry for the German error messages, I really h*te localized error messages (and I can't repeat that too many times!).

Answer 1

You can try this,

Criteria criteria = getSession().createCriteria(Task .class);                                 
criteria.createAlias("owner.id", "filterUsers");                                              
criteria.add(Restrictions.in("filterUsers", <List that contains user ids>));
