JDBC模板的Spring回滚问题

时间：2014-09-02 15:33:06

标签： spring rollback jdbctemplate transactional

我有2个插入/更新语句，我想在Spring事务中包装。如果任何一个语句失败，我想要回滚语句。我尝试使用以下方案对此进行测试：

我的application有一个数据库约束，它的CODE最多只能是25个字符。我通过提供过大的application来保存第二个CODE，从而强制违反约束条件。

我希望application A上的第一次插入/更新会被回滚。但是我的测试表明情况并非如此。

我不太确定我错过了什么......

我的转化测试： 

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"));
}
}

控制台输出：

我认为在junit测试中@Transactional太晚了

您需要将其移动到dao（或创建业务对象层）

当spring创建ctx.getBean时，它需要代理该类以应用事务

看看这些是否有帮助 Does Spring @Transactional attribute work on a private method?
