我正在使用 Spring 3.1.1.RELEASE 和 JUnit 4.8.1。在我的测试课上,我想模拟一个私有字段并发现“ReflectionTestUtils”的美妙之处......
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class OrderServiceTest extends AbstractTransactionalJUnit4SpringContextTests
…
@Autowired
private OrderService m_orderSvc;
@Test
public void testGetPDOrders() throws QuickBaseException, Exception {
…
ReflectionTestUtils.setField(m_orderSvc, "m_orderDao", mockOrderDao);
下面是我试图模拟的类和领域......
@Service("orderService")
@Transactional
public class OrderServiceImpl implements OrderService {
…
@Autowired
private OrderDAO m_orderDao;
令人失望的是,我收到以下错误。我读过这是因为我的类被标记为“@Transactional”,但我找不到足够的解决方法,而且仅仅为了适应 JUnit 而编写 setter 方法似乎是一种浪费。有人对我如何将模拟对象注入私有字段有其他建议吗?
