java.lang.AssertionError：預期狀態：<200>但原為：<404>

Question

我知道這個問題有很多類似的帖子。 我嘗試實現所有功能，但沒有為我工作。 請幫助我為什么我會收到此錯誤java.lang.AssertionError：預期狀態：<200>，但是是：<404>

我嘗試實現MediaType.APPLICATION_JSON注釋@EnableWebMvc，但無法正常工作

我是否還需要包含標題才能使其正常工作？ 請告訴我

我寫的代碼是：

控制器類：

@EnableWebMvc
@Controller
public class Controller {

@RequestMapping(value = "/app/data", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<ResponseData> DataInquiry(
            @RequestBody RequestData requestData,
            @RequestHeader(value = Constants.ID, required = false) String transactionId) {
        //Do some action
        return new ResponseEntity<ResponseData>(responseData, headers, HttpStatus.OK);
}

ControllerTest類：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath*:spring/beanRefContext.xml"})
@WebAppConfiguration
public class ControllerTest{

    public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(),
            MediaType.APPLICATION_JSON.getSubtype(),
            Charset.forName("utf8"));

private MockMvc mockMvc;

    @Autowired 
    WebApplicationContext wac; 

ObjectMapper mapper;
    AnnotationMethodHandlerAdapter adapter;
    MockHttpServletRequest request;
    MockHttpServletResponse response;

@Before
    public void setUp() {
        System.out.println("Before method execution in CommonInquiryControllerTest class ");
        //this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
        MockitoAnnotations.initMocks(this);
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();

        adapter = new AnnotationMethodHandlerAdapter();
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();
        mapper = new ObjectMapper();
    }

@Test
    public void InquiryDataTest() throws Exception, JsonProcessingException
    {
        RequestData anObject = new RequestData();

        anObject.setId("1234");
        anObject.setQualifier("someData");     

        mapper = new ObjectMapper();
        mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);
        ObjectWriter ow = mapper.writer().withDefaultPrettyPrinter();
        String requestJson=ow.writeValueAsString(anObject );

        assertNotNull(anObject.getId());
        assertNotNull(anObject.getQualifier());

        ResultActions resultActions = mockMvc
                .perform(post("/app/data")
                .contentType(MediaType.APPLICATION_JSON)
                .accept(MediaType.APPLICATION_JSON)
                .content(mapper.writeValueAsBytes(requestJson)));

            resultActions.andExpect(status().isOk());

            //This will print the response JSON string
            resultActions.andDo(MockMvcResultHandlers.print());

        Assert.assertEquals(200, response.getStatus());
}

Answer 1

即使啟用WebMvc，也需要掃描控制器以自動注冊控制器和URL映射.component-scan掃描軟件包以在應用程序上下文中查找和注冊bean。

<context:component-scan base-package="com.mycompany.xyz" />

我懷疑上下文xml中沒有組件掃描。如果是這樣，請在beanRefContext.xml中添加此語句。
