テストコンテキストの@TransactionalテストのPlatformTransactionManagerの取得に失敗しました

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

Java.lang.IllegalStateException: Failed to retrieve PlatformTransactionManager for @Transactional test for test context [DefaultTestContext@d8355a8 testClass = EHCacheTest, testInstance = com.hibernate.query.performance.EHCacheTest@3532ec19, testMethod = testTransactionCaching@EHCacheTest, testException = [null], mergedContextConfiguration = [MergedContextConfiguration@59fa1d9b testClass = EHCacheTest, locations = '{}', classes = '{class com.hibernate.query.performance.config.ApplicationConfig, class com.hibernate.query.performance.config.CachingConfig}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{}', contextLoader = 'org.springframework.test.context.support.AnnotationConfigContextLoader', parent = [null]]].

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({})
javaspringhibernatejunittransactions

@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;
    }
