Example 1 with JpaParameterExpression

use of org.hibernate.query.criteria.JpaParameterExpression in project hibernate-orm by hibernate.

the class CompositeParameterTests method testDeTypedInPredicateCriteria.

@Test
public void testDeTypedInPredicateCriteria(SessionFactoryScope scope) {
    final HibernateCriteriaBuilder builder = scope.getSessionFactory().getCriteriaBuilder();
    final JpaMetamodel jpaMetamodel = scope.getSessionFactory().getRuntimeMetamodels().getJpaMetamodel();
    final EntityDomainType entityDescriptor = jpaMetamodel.entity(SimpleEntity.class);
    final SingularAttribute attribute = entityDescriptor.getSingularAttribute("composite");
    scope.inTransaction((session) -> {
        final JpaCriteriaQuery criteria = builder.createQuery(SimpleEntity.class);
        final JpaRoot root = criteria.from(entityDescriptor);
        final Path attrPath = root.get(attribute);
        final JpaParameterExpression parameter = builder.parameter(SimpleComposite.class);
        criteria.where(builder.in(attrPath, parameter));
        final QueryImplementor query = session.createQuery(criteria);
        query.setParameter(parameter, new SimpleComposite());
        query.list();
    });
