我已成功将此注释用于Dao类。回滚适用于测试。

但是现在我需要回滚真实代码，而不仅仅是测试。有用于测试的特殊注释。但是哪些注释适用于非测试代码？对我来说这是一个大问题。我已经花了一天的时间。官方文档不符合我的需求。

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);
    }
}

这是一个注释可以很好地运行的测试：

@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>
   ...

是的，我回滚了交易。我刚刚为服务添加了BEAN …，然后注释@Transactional开始起作用:-)

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