如何在使用@Transactional注释时配置Spring-JUnit测试?

标签: spring hibernate junit transactional

我正在使用Spring 3.1.0.RELEASE和Hibernate 4.0.1.Final。虽然我的应用程序在我在线部署时起作用,但我在JUnit测试中测试DAO类时遇到了问题。谁能看到我做错了什么?我有这个JUnit代码......

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "file:src/main/webapp/WEB-INF/dispatcher-servlet.xml" })
@TransactionConfiguration
@Transactional
public class UsersDaoImplTest extends AbstractJUnit4SpringContextTests {

    private Registration registration;

    @Autowired
    private UsersDao usersDao;

    @Before
    public void setUp() { 
        registration = new Registration();
        registration.setUsername("myuser");
        registration.setPassword("password");
        registration.setConfirmPassword("password");
        registration.setFirstName("David");
        registration.setLastName("Robinson");
        registration.setEmail("dave@theadmiral.com");
    }   // setUp    

    @Test
    public void testSaveUser() { 
        boolean passed = true;
        try { 
            passed = usersDao.saveUser(registration);
        } catch (Exception exc) { 
            passed = false;
            exc.printStackTrace(System.err);
        }   // try
        Assert.assertTrue(passed);
    }

这是我的应用程序上下文XML文件...

为什么会话没有建立,我该如何解决这个问题?

我认为你应该扩展AbstractTransactionalJUnit4SpringContextTests而不是AbstractJUnit4SpringContextTests。
