トランザクション間でHibernate(バージョン4)のEHCacheのキャッシュ機能をテストしようとすると失敗します:Failed to retrieve PlatformTransactionManager for @Transactional test for test context
。
テスト
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { ApplicationConfig.class, CachingConfig.class }, loader = AnnotationConfigContextLoader.class)
@PersistenceContext
@Transactional
public class EHCacheTest extends AbstractTransactionalJUnit4SpringContextTests {
@Autowired
private SessionFactory sessionFactory;
@Test
public void testTransactionCaching(){
Session session = sessionFactory.getCurrentSession();
System.out.println(session.get(CustomerEntity.class, 1));
Query query = session.createQuery("from CustomerEntity where CustomerEntity.customerId<10").setCacheable(true).setCacheRegion("customer");
@SuppressWarnings("unchecked")
List<CustomerEntity> customerEntities = query.list();
System.out.println(customerEntities);
TestTransaction.flagForCommit();
TestTransaction.end();
TestTransaction.start();
Session sessionNew = sessionFactory.getCurrentSession();
System.out.println(sessionNew.get(CustomerEntity.class, 1));
Query anotherQuery = sessionNew.createQuery("from CustomerEntity where CustomerEntity.customerId<10");
anotherQuery.setCacheable(true).setCacheRegion("customer");
@SuppressWarnings("unchecked")
List<CustomerEntity> customerListfromCache = anotherQuery.list();
System.out.println(customerListfromCache);
TestTransaction.flagForCommit();
TestTransaction.end();
}
}
手動のプログラムによるトランザクション処理は、Spring 4.xが ドキュメント で提案する方法で実装されました。

エラー

それを機能させる方法は?
更新:
追加することで機能するようになりましたが、@TestExecutionListeners
は本当に必要です:
@Transactional(transactionManager = "hibernateTransactionManager")
@TestExecutionListeners({})
@Transactionalは、明示的に指定されていない場合、アプリケーションコンテキストにtransactionManagerという名前のBeanを必要とします。 @Transactionアノテーション値属性を使用して、テストで使用するトランザクションマネージャーを指定します
たとえば、hibernateTransactionManagerを使用する場合は、これを次のように指定します。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { ApplicationConfig.class, CachingConfig.class }, loader = AnnotationConfigContextLoader.class)
@PersistenceContext
@Transactional("hibernateTransactionManager")
public class EHCacheTest extends AbstractTransactionalJUnit4SpringContextTests {
}
それ以外の場合は、使用するトランザクションマネージャーの名前を変更して、デフォルト名をtransactionManagerにします。
@Bean
public PlatformTransactionManager transactionManager() { // TODO: Really need this?
final HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory().getObject());
return transactionManager;
}
