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

Example 1 with Cache

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

the class ReadWriteTest method testEntityCacheContentsAfterEvictAll.

@Test
public void testEntityCacheContentsAfterEvictAll() throws Exception {
    final List<Citizen> citizens = saveSomeCitizens();
    withTxSession(s -> {
        Cache cache = s.getSessionFactory().getCache();
        Statistics stats = sessionFactory().getStatistics();
        SecondLevelCacheStatistics slcStats = stats.getSecondLevelCacheStatistics(Citizen.class.getName());
        assertTrue("2lc entity cache is expected to contain Citizen id = " + citizens.get(0).getId(), cache.containsEntity(Citizen.class, citizens.get(0).getId()));
        assertTrue("2lc entity cache is expected to contain Citizen id = " + citizens.get(1).getId(), cache.containsEntity(Citizen.class, citizens.get(1).getId()));

Example 2 with Cache

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

the class ReadWriteTest method testMultipleEvictAll.
