Examples with Criteria org.hibernate.Criteria used on opensource projects

Example 21 with Criteria

use of org.hibernate.Criteria in project hibernate-orm by hibernate.

the class NaturalIdTest method testNaturalIdUncached.

@Test
public void testNaturalIdUncached() {
    saveSomeCitizens();
    Session s = openSession();
    Transaction tx = s.beginTransaction();
    State france = this.getState(s, "Ile de France");
    Criteria criteria = s.createCriteria(Citizen.class);
    criteria.add(Restrictions.naturalId().set("ssn", "1234").set("state", france));
    criteria.setCacheable(false);
    this.cleanupCache();
    Statistics stats = sessionFactory().getStatistics();
    stats.setStatisticsEnabled(true);
    stats.clear();
    assertEquals("Cache hits should be empty", 0, stats.getNaturalIdCacheHitCount());
    // first query
    List results = criteria.list();
    assertEquals(1, results.size());
    assertEquals("Cache hits should be empty", 0, stats.getNaturalIdCacheHitCount());
    assertEquals("Query execution count should be one", 1, stats.getNaturalIdQueryExecutionCount());
    // query a second time - result should be cached in session
    criteria.list();
    assertEquals("Cache hits should be empty", 0, stats.getNaturalIdCacheHitCount());
    assertEquals("Second query should not be a miss", 1, stats.getNaturalIdCacheMissCount());
    assertEquals("Query execution count should be one", 1, stats.getNaturalIdQueryExecutionCount());
    // cleanup
    tx.rollback();
    s.close();
}
