Question

您好，我在某些JUnit测试中遇到了Spring Hibernate会话管理的问题。

我有一个签名为@Transactional的测试类，以便为每个测试方法提供autorollback功能;在测试期间，我将三行插入数据库，然后运行本机查询（使用session.createSQLQuery（）），该查询应返回包含我刚刚保存的所有三个元素的列表，但本机查询的结果始终是空。

我试图从测试类中删除@Transactional，因此插入过程将以提交结束，在这种情况下，我的本机查询工作正常，测试为绿色但没有执行回滚（由于缺少@Transactional）。

就我个人而言，我宁愿不用@Rollback签名测试（false）并手动删除数据，所以我想知道这种奇怪的行为是否是由不正确的配置引起的。

提前致谢。

在我的Spring会话和事务管理器配置下面，测试中的有罪测试和本机查询。

Spring Config：

@Bean(name = "sessionFactory")
@Autowired
public SessionFactory getSessionFactory(final DataSource dataSource) throws Exception {
        final LocalSessionFactoryBuilder springSessionFactoryBean = new LocalSessionFactoryBuilder(dataSource);
        springSessionFactoryBean.addAnnotatedClasses(CvSentEvent.class);

        final Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.connection.driver_class", "org.postgresql.Driver");
        hibernateProperties.put("hibernate.cache.use_second_level_cache", true);
        hibernateProperties.put("hibernate.hbm2ddl.auto", "validate");
        hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
        hibernateProperties.put("hibernate.format_sql", false);
        hibernateProperties.put("hibernate.jdbc.use_scrollable_resultsets", true);
        hibernateProperties.put("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.EhCacheRegionFactory");
        hibernateProperties.put("org.hibernate.cache.ehcache.configurationResourceName", "ehcache.xml");

        springSessionFactoryBean.addProperties(hibernateProperties);

        return springSessionFactoryBean.buildSessionFactory();
    }

测试中的方法

@Override
@Transactional(readOnly = true)
public List<CvSentReport> searchByWebsiteAccount(final String website, final String account, final String cvs, final String budgetFIlter) {
        final String sql = ""
                + "select sent, website, account from (select "
                + "    sum(c.count) as sent, "
                + "    c.website, "
                + "    c.sponsoraccountname as account "
                + " from "
                + "    cvsentevents c "
                + " where "
                + "    c.website like :website "
                + "    and (c.sponsoraccountname like :account or (c.sponsoraccountname IS NULL and :account = '%%')) "
                + " group by "
                + "    c.website, "
                + "    c.sponsoraccountname ) z " + filterForCVs(cvs) + ";";

        final List<Object> list = new ArrayList<Object>();

        @SuppressWarnings("unchecked")
        final List<Object> itemList = getSession()
                .createSQLQuery(sql)
                .setParameter("website", "%" + website + "%")
                .setParameter("account", "%" + account + "%")
                .list();

        list.addAll(itemList);

        return createAListOfCvSentReports(budgetFIlter, list);

    }

测试代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { SpringJunitContext.class })
@Transactional
public class CvSentEventDaoTest {

    @Autowired
    private CvSentEventDao sut;

   @Test
    public void findAllTheItems() {
        newCvSentEvent(0, "website1", "account1", "1");
        newCvSentEvent(1, "website2", "account2", "1");
        newCvSentEvent(1, "website3", "account3", "0");

        final List<CvSentReport> actual = sut.searchByWebsiteAccount("website", "account", "all", "all");

        assertEquals(3, actual.size());
    }
}

有过类似的问题。在事务测试方法调用期间，实体无法从mem中的H2中删除。修复了在删除DAO方法中刷新当前会话的问题。
