數據不添加到數據庫中測試

Question

我有這樣的測試：

@ContextConfiguration(locations = {"classpath:/test/BeanConfig.xml"}) 
public class CandidateServiceTest extends AbstractTransactionalJUnit4SpringContextTests{ 

    @Autowired 
    CandidateService candidateService; 

    @BeforeClass 
    public static void initialize() throws Exception{ 

     UtilMethods.createTestDb(); 

    } 
    @Before 
    public void setup() { 
     TestingAuthenticationToken testToken = new TestingAuthenticationToken("testUser", ""); 
     SecurityContextHolder.getContext().setAuthentication(testToken); 
    } 

    @After 
    public void cleanUp() { 
     SecurityContextHolder.clearContext(); 
    } 
    @Test 
    public void add(){ 
     Candidate candidate = new Candidate(); 
     candidate.setName("testUser"); 
     candidate.setPhone("88888"); 
     candidateService.add(candidate);//here I should add data to database 
     List<Candidate> candidates = candidateService.findByName(candidate.getName()); 
     Assert.assertNotNull(candidates); 
     Assert.assertEquals("88888", candidates.get(0).getPhone()); 
    }     
} 

附加功能：在DAO

@Transactional 
@Service("candidateService") 
public class CandidateService { 
    public void add(Candidate candidate) { 
      Authentication auth = SecurityContextHolder.getContext().getAuthentication(); 
      String login = auth.getName(); 
      User user = utilService.getOrSaveUser(login); 
      candidate.setAuthor(user); 
      candidateDao.add(candidate); 
     } 
    ... 
} 

附加功能：

public Integer add(Candidate candidate) throws HibernateException{ 
     Session session = sessionFactory.getCurrentSession(); 
     if (candidate == null) { 
      return null; 
     } 
     Integer id = (Integer) session.save(candidate); 
     return id; 

    } 

通常candidateService.add(candidate)增加數據庫正常，但在測試中它不會添加到數據庫。我在測試後檢查數據庫以查看它。

可能是什麼問題？

Answer 1

嘗試增加周圍的方法@Transactional註釋在您的測試類。

此批註創建可與數據庫交互的會話。

Answer 2

在candidateService.add之後發出沖洗。在測試方法周圍有一個事務，一個提交（和flush）只發生在方法執行之後。您必須通過刷新會話來「僞造」提交。只需在您的測試類中注入SessionFactory，並在當前會話中調用flush。

@ContextConfiguration(locations = {"classpath:/test/BeanConfig.xml"}) 
public class CandidateServiceTest extends AbstractTransactionalJUnit4SpringContextTests{ 

    @Autowired 
    private SessionFactory sessionFactory; 

    @Test 
    public void add(){ 
     Candidate candidate = new Candidate(); 
     candidate.setName("testUser"); 
     candidate.setPhone("88888"); 
     candidateService.add(candidate);//here I should add data to database 
     sessionFactory.getCurrentSession().flush(); //execute queries to database 
     List<Candidate> candidates = candidateService.findByName(candidate.getName()); 
     Assert.assertNotNull(candidates); 
     Assert.assertEquals("88888", candidates.get(0).getPhone()); 
    }     
} 

而且ofcourse確保您findByName方法也正確實現，並使用同一個Hibernate Session！

Answer 3

您必須使用@Autowired自動連線DAO中的sessionDactory實例並且我會將@Transactional註釋放在DAO的每個方法中，而不是在他定義服務類之前。這通常是在註解驅動的Spring應用程序中完成的方式。
