Ich bekomme eine NOT NULL Constraint-Verletzung Ausnahme beim Versuch, ein Objekt vom Typ Individual in der DB einzufügen. Ich benutze hsql Version 2.3.2. Ich lasse Hibernate die DB-Tabellen für mich generieren. Im normalen Code (wo ich eine SQLServer-Datenbank verwende) funktioniert alles gut.ConstraintViolationException: NOT NULL bei Verwendung von Spring, HSQL und Hibernate
Dies ist mein individuelles Objekt, wo die ID von der Datenbank generiert wird und der Primärschlüssel der Tabelle ist.
Einzelobjekt:
@XmlRootElement
@Entity
@Table(name="INDIVIDUALS")
public class Individual {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="INDIVIDUAL_ID")
private long id;
Im HealthCareProfessional Objekt gibt es einen Link zu dem Primärschlüssel dieses Einzelobjekt:
@Entity
@Table(name="HEALTHCARE_PROFESSIONALS")
public class HealthCareProfessional {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="HEALTHCARE_PROFESSIONAL_ID")
private long id;
@ManyToOne
@JoinColumn(name = "INDIVIDUAL_ID", nullable = false, updatable = false, insertable = true)
private Individual individual;
...
Der Anwendungskontext, wo ich definieren die EntityManagerFactory wie folgt aussieht:
<jdbc:embedded-database id="dataSource" type="HSQL" />
<bean id="emf"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="/persistence-unittest.xml" />
<property name="persistenceUnitName" value="testingSetup"/>
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<!-- Create the database, please -->
<property name="generateDdl" value="true" />
</bean>
</property>
</bean>
<bean id="jpaVendorAdaptor"
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emf" />
</bean>
Meine Persistenz Xml ist definitiv ed wie folgt:
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="testingSetup">
<!-- The autodetection only works if the classes are packaged as a JAR. Doesn't work for unit tests. Go figure -->
<class>be.healthconnect.pwg.domain.individual.HealthCareProfessional</class>
<class>be.healthconnect.pwg.domain.individual.Individual</class>
<properties>
<property name="hibernate.archive.autodetection" value="" />
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
Das ist mein Unit-Test:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = {"classpath:/applicationContext-test.xml"})
@Transactional
public class IndividualDaoTest {
private static final String SSIN_JELLE= "81062205558";
private static final String NIHII = "123";
@Autowired
private IIndividualDao individualDao;
@Before
public void setUp() throws Exception {
Individual individual = buildIndividual(SSIN_JELLE);
individualDao.addIndividual(individual);
}
@Test
public void testGetIndividualsBySSIN() throws Exception {
final List<Individual> individuals = individualDao.getIndividuals(SSIN_JELLE);
Assert.assertNotNull(individuals);
Assert.assertEquals(1, individuals.size());
Individual individual = individuals.get(0);
Assert.assertNotNull(individual);
}
Und das ist die Fehlermeldung, die ich bekam:

Ich verstehe nicht, warum wirklich hsql doesn‘ t verwenden Sie die generierten Werte für die ID ...
