我正在使用 Spring 3.2.11.RELEASE、JUnit 4.12 和 Mockito 1.10.18。在我的 JUnit 测试中，如何创建 @Autowired 弹簧服务的间谍（不是模拟，间谍）？以下是服务的声明方式……</p> 

@Service("orderService")
public class OrderServiceImpl implements OrderService, InitializingBean 
{

以下是我的 JUnit 测试的设置方式……</p> 

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class ProcessPDWorkerTest extends AbstractWorkerTest
{
    …    
    @Autowired
    protected OrderService m_orderSvc;

和

      final OrderService orderSvcSpy = Mockito.spy(getTargetObject(m_orderSvc));
    …
      ReflectionTestUtils.setField(workerObj, "m_orderSvc", orderSvcSpy);

我在哪里……</p> 

protected static <T> T getTargetObject(Object proxy)
{
    if ((AopUtils.isJdkDynamicProxy(proxy)))
    {
        try
        {
            return (T) getTargetObject(((Advised) proxy).getTargetSource().getTarget());
        }
        catch (Exception e)
        {
            throw new RuntimeException("Failed to unproxy target.", e);
        }
    }
    return (T) proxy;
}

但我在“Mockito.spy(getTargetObject(m_orderSvc))”这一行得到以下异常：

或者，您可以尝试仅更改此行：

 final OrderService orderSvcSpy = Mockito.spy((OrderService)getTargetObject(m_orderSvc));
 …

这应该有效。Mockito.spy() 是一个重载的静态方法，编译器在编译时选择了 Mockito.spy(Class)。

为我工作：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class ProcessPDWorkerTest extends AbstractWorkerTest {

    …    
    @Spy
    @Autowired
    protected OrderService m_orderSvc;

    @Before
    public void initMocks() {
        MockitoAnnotations.initMocks(this);
        ReflectionTestUtils.setField(workerObj, "m_orderSvc", m_orderSvc);
    }
