MockMvc HttpMediaTypeNotSupportedException:不支持内容类型’application / json’

我收到以下异常:

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json' not supported

我的测试如下所示:

public class AvailabilityControllerTest extends BaseTest {   
    @Test
    public void createAvailability() throws Exception {
        final String createAvailabilityEndPoint = "/api/v4/companies/123/availabilities";
        final String responseName = "availabilityResponseDTO";

        AvailabilityDTO availabilityDTO = new AvailabilityDTO();

        MvcResult mvcResult = mockMvc.perform(
                MockMvcRequestBuilders.post(createAvailabilityEndPoint)
                        .contentType(MediaType.APPLICATION_JSON_VALUE)
                        .accept(MediaType.APPLICATION_JSON_VALUE)
                        .content(new ObjectMapper().writeValueAsString(availabilityDTO)))
                .andExpect(MockMvcResultMatchers.status().isCreated())
                .andReturn();
    }

使用BaseTest:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = TestConfiguration.class)
@AutoConfigureMockMvc
public class BaseTest {

    @Autowired
    protected MockMvc mockMvc;

}

TestConfiguration看起来像这样:

@Configuration
@ComponentScan(
        basePackages = "com.app",
        excludeFilters = {
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = App.class)
        }
)
public class TestConfiguration {

    @Bean
    public ErrorAttributes errorAttributes() {
        return new DefaultErrorAttributes();
    }
}

AvailabilityController看起来像这样:

@RestController
@RequestMapping("/api/v4/companies")
public class AvailabilityController {

    public static final String ACCEPT_APP_JSON = "Accept=" + AcceptableMediaType.APPLICATION_JSON;

    @Autowired
    private AvailabilityFacade availabilityFacade;

@RequestMapping(value = "/{companyId}/employees/{employeeId}/availabilities", method = RequestMethod.GET)
    public List<AvailabilityEventResponseDTO> getUserAvailabilities(@PathVariable String companyId,
                                                                    @PathVariable String employeeId) {
        return availabilityFacade.getUserAvailabilities(employeeId);
    }

    @RequestMapping(value = "/{companyId}/availabilities", method = RequestMethod.POST, headers = ACCEPT_APP_JSON, consumes = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<AvailabilityResponseDTO> createAvailability(@PathVariable String companyId,
                                                                      @Valid @RequestBody AvailabilityDTO availabilityDTO) {
        return new ResponseEntity<>(
                availabilityFacade.createAvailability(companyId, availabilityDTO),
                HttpStatus.CREATED
        );
    }
}

基本上GET请求适用于MockMvc,但POST不支持并返回此HttpMediaTypeNotSupportedException.我试图在请求和控制器中添加和删除接受和内容类型的标头,这似乎不起作用.

此问题似乎与Spring integration test with mockmvc throws org.springframework.web.HttpMediaTypeNotSupportedException: Content type ‘application/json’ not supported有关,但在这种情况下删除TestConfiguration中的excludeFilters不允许Spring解释上下文.另外,我不确定Karl R的意思是“在我的类路径中包含一个serverruntime”.

任何帮助表示赞赏.

最佳答案
我认为你应该将@EnableWebMvc添加到你的TestConfiguration中.

@Configuration
@ComponentScan(
     basePackages = "com.app",
    excludeFilters = {
            @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, 
              classes = App.class)
    }
)
@EnableWebMvc
public class TestConfiguration {
