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);
    }
}

这里是说明很好地发挥作用的一个考验:

@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,我转回交易。 我刚刚为这项服务增添了别名。

<bean id="service" class="main.MyClass">
    <property name="employeeDao" ref="employeeDao" />
</bean>

感谢大家, 俄罗斯不会忘记你们!
