休眠：單元測試回滾產生時完成「交易未成功開始」

Question

當我做單元測試回滾測試後引發以下異常。

我感覺事務在回滾之後關閉並創建一個新事務。然而，這個新的程序並沒有啓動，當測試試圖關閉它時會產生錯誤。

測試：

package de.company.backend.web; 

    import org.junit.Test; 
    import org.junit.runner.RunWith; 
    import org.springframework.test.context.ContextConfiguration; 
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
    import org.springframework.transaction.annotation.Transactional; 

    import de.company.backend.hibernate.HibernateUtil; 

    @RunWith(SpringJUnit4ClassRunner.class) 
    @Transactional 
    @ContextConfiguration(locations = { "/app-context.xml", "/test-app-context.xml" }) 
    public class RollbackTest { 

     @Test 
     public void testRollback() { 
      HibernateUtil.rollback(); 
     } 

    } 

形式appcontext

<!-- make @Transactional working --> 
<tx:annotation-driven transaction-manager="transactionManager" /> 
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
    <property name="dataSource" ref="dataSource" /> 
    <property name="sessionFactory" ref="sessionFactory" /> 
</bean> 

<!-- Use open session in view pattern for json/rest controller + transaction is similarly opened/closed --> 
<mvc:interceptors> 
    <bean class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor"> 
     <property name="sessionFactory" ref="sessionFactory" />    
     <property name="flushModeName"> 
      <value>FLUSH_AUTO</value> 
     </property> 
    </bean> 
</mvc:interceptors> 

的HibernateUtil

package de.company.backend.hibernate; 

    import org.hibernate.Session; 
    import org.hibernate.SessionFactory; 
    import org.hibernate.Transaction; 

    import de.company.backend.spring.SpringFactory; 

    public class HibernateUtil { 

     public static SessionFactory getSessionFactory() { 
      return (SessionFactory) SpringFactory 
        .generate("sessionFactory"); 
     } 

     public static Session getCurrentSession() { 
      return getSessionFactory().getCurrentSession(); 
     } 

     public static Transaction getCurrentTransaction() { 
      Transaction transaction = getCurrentSession().getTransaction(); 
      return transaction; 
     } 

     public static void flush() { 
      getCurrentSession().flush(); 
     } 

     public static void commit() { 
      getCurrentTransaction().commit(); 
     } 

     public static void rollback() { 
      Transaction transaction = getCurrentTransaction(); 
      transaction.rollback(); 
     } 

    } 

是否有人有一些建議嗎？

非常感謝！
