我有2個插入/更新語句，我想在Spring事務中包裝。如果兩個語句都失敗了，我想讓語句回滾。我試着用下面的場景來測試這一點：JDBC模板的彈簧回滾問題
我有一個application具有DB約束它的CODE只能是最多25個字符。我強制違反約束，同時通過提供太大的CODE來節省第二個application。
我期望第一次插入/更新application A會被回滾。但是，我的測試表明，情況並非如此。
我不太清楚，我缺少的是什麼？
我TRANSATION測試：
public class SpringTransactionTest {
private static final Logger LOGGER = LoggerFactory.getLogger(SpringTransactionTest.class.getName());
private ApplicationDAO applicationDAO = SpringUtils4Test.getBean(ApplicationDAO.class);
@Transactional
public void doStuff() {
Application a = new Application();
a.setCode("A");
Application b = new Application();
b.setCode("BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB");
a = applicationDAO.insertOrUpdate(a);
LOGGER.debug("a: "+a.getIdentifier());
b = applicationDAO.insertOrUpdate(b);
LOGGER.debug("b: "+b.getIdentifier());
}
@Before
public void cleanIt() {
Application a = applicationDAO.getApplicationByCode("A");
if(a != null && a.getIdentifier() > 0) {
applicationDAO.deleteById(a.getIdentifier());
LOGGER.debug("removed A");
}
Application b = applicationDAO.getApplicationByCode("BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB");
if(b != null && b.getIdentifier() > 0) {
applicationDAO.deleteById(b.getIdentifier());
LOGGER.debug("removed B");
}
}
@Test
public void runTransactionTest() {
try {
doStuff();
} catch (org.springframework.jdbc.UncategorizedSQLException e) {
e.printStackTrace();
}
Assert.assertNull("A should be null, but instead A was found", applicationDAO.getApplicationByCode("A"));
Assert.assertNull("B should be null, but instead B was found", applicationDAO.getApplicationByCode("B"));
}
}
