Function not supported from hibernate - spring

Question

I'm unit testing my DAOs using spring. I am using JPA + Hibernate.
For my tests i'm using the following hsqldb version:
<dependency>
<groupId>hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>1.8.0.10</version>
<scope>test</scope>
</dependency>
And here's my persistence.xml for my unit tests:
<persistence-unit name="unit-test-pu" transaction-type="RESOURCE_LOCAL">
<properties>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:mem:testdb"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.use_sql_comments" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="create"/>
</properties>
</persistence-unit>
This is my test class:
#ContextConfiguration("/spring/test-context.xml")
#TestExecutionListeners({TransactionalTestExecutionListener.class})
#Transactional
public class BaseDaoTestCase extends AbstractJUnit4SpringContextTests {
#Autowired
private MockEntityDao dao;
#Test
public void testSave_success() {
MockEntity e = new MockEntity();
dao.save(e);
assertNotNull(e.getId());
}
}
Note: the idea is to test my DAOs against an in memory HSQLDB instance. Each test method runs within a transaction managed by spring.
Unfortunately, when i run this i get the following exception from hibernate:

The implementation of my DAO's save() method is as follows:
entityManager.persist(entity);
I'm using the following hibernate version:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.0.Final</version>
<scope>compile</scope>
</dependency>
Does anyone have a clue on what's going on?

Answer 1

I had similar Problem. After I update my dependencies (especially hsqldb) to:
<hibernate-core-version>4.1.5.Final</hibernate-core-version>
<spring.version>3.1.2.RELEASE</spring.version>
<hsqldb.version>2.2.8</hsqldb.version>
...
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>${hsqldb.version}</version>
</dependency>
my problem is resolved.

Answer 2

Which mocking framework are you using? I'm just learning to work with mocks so this is just a wild guess but make sure you've done everything necessary to initialize the mock. Maybe the problem has something to do with how the test is being setup.

Answer 3

I'm having the same problem working with JPA + Hibernate + HSQLDB, but not spring.
Here is my code:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit");
EntityManager em = emf.createEntityManager();
EntityTransaction tr = em.getTransaction();
tr.begin();
em.persist(new MyEntity());
tr.commit();
em.close();
emf.close();
That throws me the same This function is not supported exception, but if I do it without the transaction, it doesn't. Like this:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit");
EntityManager em = emf.createEntityManager();
em.persist(new MyEntity());
em.close();
emf.close();
The problem now, is that I don't see the changes reflected on database.
