Ниже приведен пример того, как вы можете создать весенний конфиг с помощью теста hslqdb
Он автоматически обнаруживает все ваши схемы из @Table (schema = ...) и создает их для вас.
Если это только для тестирования, это должно работать для вас:
import org.reflections.Reflections; //maven artifact: 'org.reflections:reflections:0.9.9-RC1'
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Bean( name = "testSessionFactory" )
@Lazy
public LocalSessionFactoryBean getTestSessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

А вот тестовый образец:
@ContextConfiguration( classes = CollectionConfig.class )
@DirtiesContext( classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD )
public class DaoMappingTest extends AbstractTestNGSpringContextTests {
@Autowired
private SessionFactory testSessionFactory;
@Test
public void thatMovieIsSaved() {
Movie killBill = getKillBillMovie0();
saveToDb( Arrays.asList(killBill) );
Session querySession = testSessionFactory.openSession();
List<Movie> movies = querySession.createQuery( "from Movie" ).list();
querySession.close();
assertThat( movies ).containsExactly( killBill );
}
@Test
public void that2MoviesIsSaved() {
Movie killBill = getKillBillMovie0();
Movie terminator = getTerminatorMovie1();
saveToDb( Arrays.asList( killBill, terminator ) );
Session querySession = testSessionFactory.openSession();
List<Movie> movies = querySession.createQuery( "from Movie" ).list();
querySession.close();
assertThat( movies ).containsOnly( killBill, terminator );
}
private void saveToDb( List<?> objects ) {
Session session = testSessionFactory.openSession();
session.beginTransaction();
for( Object obj : objects) {
session.save( obj );
}
session.getTransaction().commit();
session.close();
}
@AfterSuite
public void tearDown() {
testSessionFactory.close();
}
}
