Java Spring事务测试。嵌套事务不是'；他没有后退

我正在尝试使用DbUnit+Spring（4.1.1）tests+MyBatis+Oracle实现集成测试

我正在做以下工作：

测试课前：（a）公开交易； （b） 插入只读公共父数据集（适用于所有测试方法）

将测试类标记为事务类（propogation=NESTED）。因此，每个测试方法都应该在自己的事务中执行，然后回滚它。嵌套-因为我想访问父事务中“before test class”方法插入的数据（因此propogation=REQUIRED_NEW不是选项）

测试类回滚父事务后

问题是嵌套事务不会回滚。如果方法A插入数据，方法B就会看到该数据

可能是JDBC（11.2.0.1.0）驱动程序问题（因为spring使用保存点方法）还是Oracle（11g）

我附带了简化（一体式）测试来演示此问题：

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration({ "/core-dao-config.xml", "/test-context.xml" })
    @TestExecutionListeners({DependencyInjectionTestExecutionListener.class,
            TransactionTest.class, TransactionalTestExecutionListener.class})
    @Transactional(propagation = Propagation.NESTED)

    public class TransactionTest extends AbstractTestExecutionListener
    {

    public TransactionTest(){}

    DataSource dataSource;

    DataSourceTransactionManager txManager;

    protected void injectDependencies(final TestContext testContext) throws Exception {

        dataSource = testContext.getApplicationContext().getBean(DataSource.class);
        txManager = testContext.getApplicationContext().getBean(DataSourceTransactionManager.class);

    }

    @Override
    public void beforeTestClass(TestContext testContext) throws Exception {
        injectDependencies(testContext);
        final TransactionStatus transaction = txManager.getTransaction(new DefaultTransactionAttribute());
        testContext.setAttribute("parenttx", transaction);
    }    

    @Autowired
    SomeDao someDao;

    @Test
    public void testTx() {
        final DbObject domainObject = new DbObject();
        domainObject.setKey(-303L);
        someDao.add(domainObject);

        assertNotNull(someDao.findByKey(-303L));
    }

    @Test
    public void testInserted() {
        assertNull(someDao.findByKey(-303L));
    }

    @Override
    public void afterTestClass(TestContext testContext) throws Exception {
        final TransactionStatus parenttx =(TransactionStatus)testContext.getAttribute("parenttx");
        Validate.notNull(parenttx);
        txManager.rollback(parenttx);
    }
}

因此，当testTx方法插入testInserted记录时，就会看到它并失败。但日志显示数据被回滚：
