我在尝试将Hibernate事务中的更改推送到数据库以使DbUnit在我的测试用例中正常工作时遇到问题.似乎DbUnit没有看到Hibernate所做的更改,因为它们还没有在事务结束时提交……而且我不确定如何重构我的测试用例以使其工作.
这是我过度简化的测试用例来证明我的问题： –
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:applicationContext-test.xml"
})
@TransactionConfiguration(transactionManager = "transactionManager")
@Transactional
public class SomeTest {
@Autowired
protected DataSource dataSource;
@Autowired
private SessionFactory sessionFactory;
@Test
public void testThis() throws Exception {
Session session = sessionFactory.getCurrentSession();
assertEquals("initial overlayType count",4,session.createQuery("from OverlayType").list().size());
//-----------
// Imagine this block is an API call,ex: someService.save("AAA");
// But for the sake of simplicity,I do it this way
OverlayType overlayType = new OverlayType();
overlayType.setName("AAA");
session.save(overlayType);
//-----------
// flush has no effect here
session.flush();
assertEquals("new overlayType count",5,session.createQuery("from OverlayType").list().size());
// pull the data from database using dbunit
IDatabaseConnection connection = new DatabaseConnection(dataSource.getConnection());
connection.getConfig().setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY,new MysqLDataTypeFactory());
QueryDataSet partialDataSet = new QueryDataSet(connection);
partialDataSet.addTable("resultSet","select * from overlayType");
ITable actualTable = partialDataSet.getTable("resultSet");
// FAIL: Actual row count is 4 instead of 5
assertEquals("dbunit's overlayType count",actualTable.getRowCount());
DataSourceUtils.releaseConnection(connection.getConnection(),dataSource);
}
}
我使用DbUnit的全部想法是： –
>调用someService.save(…)将数据保存到多个表中.
>使用DbUnit从XML获取预期的表.
>使用DbUnit从数据库中获取实际表.
> Dosertion.assertEquals(expectedTable,actualTable);.
但是,在这一点上,我无法让DbUnit看到Hibernate在事务中所做的更改.
我应该如何改变以使DbUnit与Hibernate事务很好地协作？
谢谢.
