java - testException = [null] 与 Hibernate 和 SpringMVC

Question

我正在尝试运行以下测试。在本例中，只是一个空白测试来尝试一下，但由于某种原因它不起作用。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class)
@Transactional
public class UserHibernateDaoTest {

    private static final long USERID = 1;
    private static final long NONEXISTENTUSERID = -1;
    private static final String FIRSTNAME = "TestFirstName";
    private static final String LASTNAME = "TestLastName";
    private static final String EMAIL = "test1@mail.com";
    private static final String PASSWORD = "TestPassword";
    private static final String PHONENUMBER = "0000000";
    private static final String ROLE = "USER";

    @PersistenceContext
    private EntityManager em;

    private UserHibernateDao userHibernateDao;  
    private JdbcTemplate jdbcTemplate;


    @Before
    @Transactional
    public void setUp() {
            this.userHibernateDao = new UserHibernateDao();
            User u;
            u = new User();
            u.setUserid(123);
            u.setFirstName(FIRSTNAME);
            u.setLastName(LASTNAME);
            u.setEmail(EMAIL);
            u.setPassword(PASSWORD);
            u.setPhoneNumber(PHONENUMBER);
            u.setRole(ROLE);
            em.persist(u);

    }

    @Rollback
    @Test
    public void testCreate() {
            // Trying to run this empty test
    }
}

运行时得到以下信息:

INFO: Began transaction (1) for test context [DefaultTestContext@16fb356 testClass = UserHibernateDaoTest, testInstance = ar.edu.itba.paw.persistence.UserHibernateDaoTest@6bc248ed, testMethod = testCreate@UserHibernateDaoTest, testException = [null], mergedContextConfiguration = [MergedContextConfiguration@224b4d61 testClass = UserHibernateDaoTest, locations = '{}', classes = '{class ar.edu.itba.paw.persistence.TestConfig}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader', parent = [null]]]; transaction manager [org.springframework.orm.jpa.JpaTransactionManager@23a9ba52]; rollback [true]
Jan 15, 2020 1:17:10 PM org.springframework.test.context.transaction.TransactionContext endTransaction
INFO: Rolled back transaction for test context [DefaultTestContext@16fb356 testClass = UserHibernateDaoTest, testInstance = ar.edu.itba.paw.persistence.UserHibernateDaoTest@6bc248ed, testMethod = testCreate@UserHibernateDaoTest, testException = java.lang.IllegalArgumentException: Unknown entity: ar.edu.itba.paw.models.User, mergedContextConfiguration = [MergedContextConfiguration@224b4d61 testClass = UserHibernateDaoTest, locations = '{}', classes = '{class ar.edu.itba.paw.persistence.TestConfig}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader', parent = [null]]].

如果将 Rollback() 更改为 Rollback(false) 我得到:

 RollbackException: Transaction marked as rollbackOnly

有什么想法可以解决这个问题吗？

如果您觉得有必要，我在 this question. 中发布了我的 TestConfig

Answer 1

Spring 没有找到你的 User 类作为实体。所以它不知道 User 是一个实体。需要在TestConfig类中添加实体包进行组件扫描。

@ComponentScan({"src.main.java.ar.edu.itba.paw.persistence", "ar.edu.itba.paw.models" })
