WebApplicationContext不会自动装配

我写这个测试课：

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
public class CandidateControllerTest {
        @Mock(name = "candidateService")
        private CandidateService candidateService;
        @InjectMocks
        private CandidateMenuController candidateMenuController = new CandidateMenuController();
        @Autowired
        WebApplicationContext wac;
        MockMvc mockMvc;
        @Before
        public void before() {
            mockMvc = MockMvcBuilders.webApplicationContextSetup(wac).build();
         }
    }

但：

代码执行后，我看到下一个跟踪：

我该如何解决我的问题？

我更改代码：

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@WebAppConfiguration
public class CandidateControllerTest {
    @Mock(name = "candidateService")
    private CandidateService candidateService;
    @InjectMocks
    private CandidateMenuController candidateMenuController = new CandidateMenuController();
    @Autowired
    WebApplicationContext wac;
    MockMvc mockMvc;
    @Before
    public void before() {
        MockitoAnnotations.initMocks(this);
        // this.mockMvc =
        // MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
         mockMvc = MockMvcBuilders.webApplicationContextSetup(wac).build();
    }
...
}

回答：

除非您将添加到测试类中WebApplicationContext，ApplicationContext否则不只是一个@WebAppConfiguration。

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class CandidateControllerTest { ... }

除了@RunWith注释，您还可以扩展spring便利类之一。

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@WebAppConfiguration
public class CandidateControllerTest extends AbstractJUnit4SpringContextTests { ... }
