Spring / Hibernate / JUnit - No Hibernate Session bound to Thread
- by Marty Pitt
Hi
I'm trying to access the current hibernate session in a test case, and getting the following error:
org.hibernate.HibernateException: No
Hibernate Session bound to thread, and
configuration does not allow creation
of non-transactional one here at
org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)
at
org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:574)
I've clearly missed some sort of setup, but not sure what.
Any help would be greatly appreciated. This is my first crack at Hibernate / Spring etc, and the learning curve is certainly steep!
Regards
Marty
Code follows:
The offending class:
public class DbUnitUtil extends BaseDALTest {
@Test
public void exportDtd() throws Exception
{
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
Connection hsqldbConnection = session.connection();
IDatabaseConnection connection = new DatabaseConnection(hsqldbConnection);
// write DTD file
FlatDtdDataSet.write(connection.createDataSet(), new FileOutputStream("test.dtd"));
}
}
Base class:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
public class BaseDALTest extends AbstractJUnit4SpringContextTests {
public BaseDALTest()
{
super();
}
@Resource
protected SessionFactory sessionFactory;
}
applicationContext.xml:
