我使用H2数据库与Spring，Hibernate和DBUnit进行测试。我也使用c3p0连接池。我的一个测试，无论如何奇怪地在成功传递后立即失败，在回滚测试执行后发生一些异常。我的连接网址为jdbc:h2:file:h2/db;MODE=MySQL;LOCK_MODE=0以下是测试本身。
@Test
public testFindLatestNotSynced() {
BuyWine buyWine = buyWineDao.findLatestNotSynced(1).get(0);
assertNotNull(buyWine);
assertEquals("3", buyWine.getId());
buyWine.setSyncDate(new Date());
buyWine = buyWineDao.findLatestNotSynced(1).get(0);
assertNotNull(buyWine);
assertEquals("1", buyWine.getId());
buyWine.setSyncDate(new Date());
/* Checking empty. */
List<BuyWine> wines = buyWineDao.findLatestNotSynced(1);
assertEquals(0, wines.size());
}
setup()和拆解方法是。
@Autowired
private IDatabaseConnection dbUnitConnection;
@Autowired
private FlatXmlDataSetBuilder datasetBuilder;
private ReplacementDataSet dataSet;
...
@Before
public void setUp() throws Exception {
if (initialDatasetName != null) {
/* Using replacement data set, so we can use null values in the first row. */
dataSet = new ReplacementDataSet(
datasetBuilder.build(getClass().getResourceAsStream(initialDatasetName)));
dataSet.addReplacementObject("[NULL]", null);
dataSet.setStrictReplacement(true);
DatabaseOperation.CLEAN_INSERT.execute(dbUnitConnection, dataSet);
}
}
@After
public void tearDown() throws Exception {
if (dataSet != null) {
DatabaseOperation.DELETE_ALL.execute(dbUnitConnection, dataSet);
}
dbUnitConnection.close();
DataSourceUtils.releaseConnection(connection, dataSource);
}
它看起来非常像H2中的错误，但我想找出一些解决方法。
