WebApplicationContext不会自动装配

Question

我写这个测试类:

@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:

我该怎么做才能解决我的问题？

UPDATE

我改变代码:

@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();

    }
...
}

Answer 1

没有WebApplicationContext唯一的ApplicationContext,除非你添加@WebAppConfiguration到您的测试类.

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

@RunWith您也可以扩展一个弹簧便利类,而不是注释.

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

Answer 2

我使用TestNG和Mockito也有同样的问题.

事实证明wac不是自动装配的,并且在@BeforeTest方法中可用,但是在@Test方法中.

我感动了这个

mockMvc = MockMvcBuilders.webApplicationContextSetup(wac).build();

@Test方法和presto,它的工作原理!
