我的entityManager persist()从序列获取id并将其放到我的Image对象中,但Image对象本身没有显示在数据库中.EntityManager.flush()给出了一个错误,所以我不能这样提交.这是我的代码.

@Repository
public class ImageDaoImpl extends BaseDao implements ImageDao {

@PersistenceContext
protected EntityManager entityManager;

@Override
@Transactional
public void create(Image image) {       
    JpaTemplate jpaTemplate = getJpaTemplate(entityManager);
    jpaTemplate.persist(image);
}

@Repository
public class BaseDao {

private JpaTemplate jpaTemplate;


public JpaTemplate getJpaTemplate(EntityManager entityManager){
    if(jpaTemplate == null)
        jpaTemplate = new JpaTemplate(entityManager);
    return jpaTemplate;
}

<bean id="entityManagerFactory"
       class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
       p:dataSource-ref="dataSource">
       <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="showSql" value="true" />
                <property name="generateDdl" value="true" />
                <property name="databasePlatform" value="org.hibernate.dialect.PostgreSQLDialect" />
            </bean>
        </property>
        <property name="persistenceUnitName" value="sample"></property>
    </bean>

我正在运行一个简单的JUnit测试再次应用程序DAO.问题是我总是得到:

javax.persistence.RollbackException: Transaction marked as rollbackOnly

JUnit测试是:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:com/my/app/context.xml"}
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = false)
@Transactional
public class PerformanceTest {

    @Test
    @Transactional(propagation= Propagation.REQUIRES_NEW)
    @Rollback(false)
    public void testMsisdnCreationPerformance() {
        // Create a JPA entity

        // Persist JPA entity
    }
}

正如您所看到的,我明确表示不会回滚此方法.

Spring JUnit是否支持始终将回滚设置为true？
