春季啓動測試期待ConstraintViolationException但收到JpaSystemException

試圖在彈簧啓動時針對JPA圖層執行測試分片，每個guide但驗證約束似乎不會觸發。我的設置如下春季啓動測試期待ConstraintViolationException但收到JpaSystemException

@SpringBootApplication 
public class MyApplication { 

    public static void main(String[] args) { 
     SpringApplication.run(MyApplication.class, args); 
    } 
} 

@Configuration 
@EnableAutoConfiguration 
@EnableJpaRepositories(basePackages = "com.myapp.core.dao") 
@EntityScan(basePackages = {"com.myapp.core.entity"}) 
    public class CoreConfig { 
} 

@Entity 
@Table(name = "users") 
public class Users implements Serializable { 

    private static final long serialVersionUID = 1L; 
    @Id 
    @NotNull 
    @Size(min = 1, max = 50) 
    @Column(name = "username") 
    private String username; 

    ... 
} 


public interface UsersDAO extends CrudRepository<Users, String> { 
} 


@RunWith(SpringRunner.class) 
@DataJpaTest 
@AutoConfigureTestDatabase(replace=Replace.NONE) 
public class UsersDAOIT { 

    @Autowired 
    private UsersDAO usersDAO; 

    private static final String USER_NAME = RandomStringUtils.randomAlphabetic(50); 
    private static final String PASSWORD = RandomStringUtils.randomAlphabetic(50); 

    private Users p; 

    @Before 
    public void onStartUp() { 
     p = new Users(); 
     p.setUsername(USER_NAME); 
     p.setPassword(PASSWORD); 
     p.setEnabled(Boolean.TRUE); 
    } 

    @Test(expected = ConstraintViolationException.class) 
    public void testSave_NullUsername() { 
     p.setUsername(null); 
     usersDAO.save(p); 
    } 
}

與所有的設置，測試結果如下：

我很難找到那裏驗證是自動配置的位置。我確實看到Hibernate-validator作爲一個依賴包含在內，甚至指定爲測試作用域，它在處理事物的db端之前似乎沒有通過驗證來響應實體。

任何想法？

在此先感謝！

這是不是我們預期，Hibernate驗證應該抓住@NotNull試圖保存不@Id之前。更進一步，有另一個測試經過時，它不應該

@Test(expected = ConstraintViolationException.class) 
    public void testSave_LongUsername() { 
     p.setUsername(RandomStringUtils.randomAlphabetic(51)); 
     usersDAO.save(p); 
    }

檢查此鏈接是否有幫助http://stackoverflow.com/questions/8922631/spring-thrown-jpasystemexception-instead-of-duplicatekeyexception –

你嘗試調用'getRootCause'或'getMostSpecificCause'方法，看看是否有你正在尋找的例外？ javadoc http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/orm/jpa/JpaSystemException.html –

@MadhusudanaReddySunnapu，這樣做並驗證驗證沒有被解僱。請參閱編輯1. – mosgjig

JPA的異常說明了一切：你不使用任何ID生成（@GeneratedValue），因此您必須在致電save()之前手動分配ID。此檢查發生在Bean Validation開始之前。

不確定您是否閱讀了編輯1上的更新，但證明不驗證bean驗證是否被調用。 @Size沒有被強制執行，表明在這個過程中沒有考慮到bean驗證。 – mosgjig

在測試中，您需要強制EntityManager刷新，因爲驗證發生在Hibernate PreInsert事件中。

所以

@RunWith(SpringRunner.class) 
@DataJpaTest 
@AutoConfigureTestDatabase(replace=Replace.NONE) 
public class UsersDAOIT { 

    @Autowired 
    private UsersDAO usersDAO; 

    @PersistenceContext 
    private EntityManager entityManager; 

    private static final String USER_NAME = RandomStringUtils.randomAlphabetic(50); 
    private static final String PASSWORD = RandomStringUtils.randomAlphabetic(50); 

    private Users p; 

    @Before 
    public void onStartUp() { 
     p = new Users(); 
     p.setUsername(USER_NAME); 
     p.setPassword(PASSWORD); 
     p.setEnabled(Boolean.TRUE); 
    } 

    @Test(expected = ConstraintViolationException.class) 
    public void testSave_NullUsername() { 
     p.setUsername(SOME_EXTRA_LONG_STRING); 
     usersDAO.save(p); 
     entityManager.flush(); 
    } 
}

基於這個原因，以及（在PreInsert事件驗證）在@Id領域的@NotNull審定會也從未解僱。生成ID（或在您的情況下必須分配）之前插入，所以他們將被創建/必須在此之前分配。
