Mockito和MockMvc方法中的Absent Code属性

Question

public class ExampleRestControllerTest {

     private MockMvc mockMvc;

     @Mock
     private MyService myService;

     @InjectMocks
     private MyRestController myRestController;

     @Before
     public void setUp() {
        MockitoAnnotations.initMocks(this);
        StandaloneMockMvcBuilder setup =    MockMvcBuilders.standaloneSetup(myService);
        mockMvc = setup.build();
}

执行MockMvcBuilders.standaloneSetup(myService);时，我返回了这个堆栈跟踪：

可能有什么不对？

谢谢

standaloneSetup()带你的控制器。也许以下示例可以帮助您：

@RunWith(MockitoJUnitRunner.class)
public class IndexControllerTest {

    private IndexController classUnderTest;

    @Mock
    private IndexService mockedService;

    @Before
    public void setUp() {
        classUnderTest = new IndexController(mockedService);
    }

    @Test
    public void testMockMvc() throws Exception{
        MockMvc mockMvc = MockMvcBuilders.standaloneSetup(classUnderTest).build();

        mockMvc.perform(get("/")).andExpect(status().isOk()).andExpect(view().name("index"));

    }
}
