I used this annotation successfully for a Dao class. And rollback works for tests.
But now I need to rollback real code, not just tests. There are special annotations for use in tests. But which annotations are for non-test code? It is a big question for me. I spent a day for that already. The official documentation did not meet my needs.
class MyClass { // this does not make rollback! And record appears in DB.
EmployeeDaoInterface employeeDao;
public MyClass() {
ApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "HibernateDaoBeans.xml" });
employeeDao = (IEmployeeDao) context.getBean("employeeDao");
}
@Transactional(rollbackFor={Exception.class})
public void doInsert( Employee newEmp ) throws Exception {
employeeDao.insertEmployee(newEmp);
throw new RuntimeException();
}
}
employeeDao is
@Transactional
public class EmployeeDao implements IEmployeeDao {
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public void insertEmployee(Employee emp) {
sessionFactory.getCurrentSession().save(emp);
}
}
And here is a test for which the annotations work well:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/HibernateDaoBeans.xml" })
@TransactionConfiguration(transactionManager = "txManager", defaultRollback = true)
@Transactional
public class EmployeeDaoTest {
@Autowired
EmployeeDaoInterface empDao;
@Test
public void insert_record() {
...
assertTrue(empDao.insertEmployee(newEmp));
}
HibernateDaoBeans.xml
...
<bean id="employeeDao" class="Hibernate.EmployeeDao">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="txManager"/>
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
...
**YES, I rolled back the transaction. I just added BEAN for the service... and then annotation @Transactional begin to work :-) **
<bean id="service" class="main.MyClass">
<property name="employeeDao" ref="employeeDao" />
</bean>
Thanks all, Russia will not forget you!
