我在理解@Transactionalspring 中的注释以及它的工作原理方面遇到了问题。

我有这个片段(VacancyService 类标记为事务性):

    @TransactionConfiguration(defaultRollback = false)
    @ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
    public class AbstractServiceTest  extends AbstractTransactionalJUnit4SpringContextTests{
           ....
           @Test
        public void delete(){
//here session opens and transaction starts 
            vacancyService.delete(vacancy.getId());

            sessionFactory.getCurrentSession().flush();

            Vacancy vacancyFromDb = vacancyService.findById(vacancy.getId());   

            sessionFactory.getCurrentSession().flush();

            Assert.assertNull(vacancyFromDb);
//here transactions commit and session close
        }
}

第二个片段:

@Controller
public class VacancyMenuController extends AbstractController{

...
   @RequestMapping("/path")
   public String delete(Model model){
  //here session opens and transaction starts 
                 vacancyService.delete(vacancy.getId());
 //here transactions commit and session close

        sessionFactory.getCurrentSession().flush();

 //here session opens and transaction starts    
    Vacancy vacancyFromDb = vacancyService.findById(vacancy.getId());
//here transactions commit and session close    

        sessionFactory.getCurrentSession().flush();


    }
}

请阅读代码中的注释并修复我的错误。

谢谢。
