Question

我有这个测试：

@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());
    }                   
}

添加功能：

@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);
        }
    ...
}

在dao中添加功能：

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)正常地添加到数据库，但在测试中它不会添加到数据库。我在测试后检查了数据库，看看它。

可能是什么问题？

Answer 1

尝试在测试类中的方法周围添加@Transactional注释。

此注释创建一个可与数据库交互的会话。

Answer 2

在candidateService.add之后发出同花。测试方法周围有一个事务，只在方法执行后才发生提交（和刷新）。你必须通过刷新会话来“伪造”提交。只需在测试类中注入SessionFactory，并在当前会话中调用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());
    }                   
}

当然，确保您的findByName方法也正确实现并使用相同的休眠会话！

Answer 3

您必须使用@Autowired在DAO中自动连接sessionDactory实例。我会将@ Transactional注释放在DAO的每个方法中，而不是在他定义服务类之前。这通常是在注释驱动的Spring应用程序中完成的方式。

数据不会在测试中添加到数据库
