Mockito在spring的间谍对象
当我尝试在unit testing中窥探一个对象时，我得到了一个例外。 这是我的unit testing文件：
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:spring/applicationContext.xml" }) public class BookingSuperManTest { BookInfoParams bookInfoParams; HttpAttributeParams httpAttributeParams; AbstractRequester requester; public void beforeStartTest(){ bookInfoParams = Mockito.spy(new BookInfoParams()); httpAttributeParams = Mockito.spy(new HttpAttributeParams()); } @Test public void step1GoToHomePage() throws BookingException{ beforeStartTest(); requester = new Step1HomePage(bookInfoParams, httpAttributeParams); requester.executeRequest(); Assert.assertNotNull(httpAttributeParams.getResponseGetRequest()); } } 我在链接分配bookInfoParams spy时得到了exception：

这是我的pom文件中的依赖项
junit junit 4.12 org.mockito mockito-core 2.0.44-beta org.powermock powermock-api-mockito 1.6.4 org.powermock powermock-module-junit4 1.6.4 cglib cglib 3.2.1 test
也许版本不兼容或我错过了什么？
它可能是依赖项的问题。 powermock-api-mockito在mockito-core版本1.10.19上有编译时依赖性，但你也定义了对版本2.0.44-beta的依赖。 这可能是类路径问题。 尝试删除版本2.0.44-beta的显式依赖2.0.44-beta 。
在2.0.32-beta版本中，Mockito团队将cglib类移到了分离的jar中 。 但是PowerMock仍然依赖于已移动的类，因此您将获得java.lang.NoClassDefFoundError。
在版本1.6.2中，Mockito类被复制到PowerMock中，但并非全部。 作为解决方法，我可能建议克隆，构建并添加到类路径mockito-cglib（ https://github.com/mockito/mockito-cglib ）。
从1.6.5开始，PowerMock将支持 Mockito 2 API，它将在5月底发布，但仍将使用cglib。 完整的Mockito 2和Bytebuddy将在1.6.5之后发布。
移植到Mockito的开发人员指南2
这是因为powermock-api-mockito对mockito-core的依赖性。 由于powermock-api-mockito被明确添加为依赖项，请删除mockito-core，这可能会导致问题
