java Spring引导控制器测试始终返回404

Question

```java  
@RunWith(SpringRunner.class)
@SpringBootTest(classes = DemoApplication.class)
@AutoConfigureMockMvc
@TestPropertySource(locations = "classpath:application-integrationtest.properties")
@EnableAutoConfiguration(exclude = {WebMvcAutoConfiguration.class})
public class DemoControllerTest {

    @Autowired
    private MockMvc mvc;

    @Autowired
    private WebApplicationContext context;

    @Before
    public void setup() {
        this.mvc = MockMvcBuilders.webAppContextSetup(context).dispatchOptions(true).build();
    }

    @Test
    public void getApplicationVersionTest() throws Exception {
        mvc.perform(get("/demo/version").contentType(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk());
    }
}

我已经从v2升级了我的springboot版本。1.7至v2。2.5从那以后，我的控制器测试失败了，因为mock返回404 for all。由于bean实例化错误，我已排除了WebMvcAutoConfiguration类。现在，mock返回404

I have upgraded my Spring Boot version from v2.1.7 to v2.2.5 and since then my controller tests are failing because the mock is returning 404 for all. I have excluded `WebMvcAutoConfiguration` class for bean instantiation error. Now the mock returns 404 for all.

Below is the my controller class:

    @PropertySource(ignoreResourceNotFound = true, value = "classpath:app-version.properties")
    @RestController
    @RequestMapping("/demo")
    public class DemoController extends CommonController {
        private static final Logger LOGGER = LoggerFactory.getLogger(DemoController.class);
        private DemoService demoService;
        @Value("${environment.name:unknown}")
        private String environmentName;
        @Value("${buildNumber:unknown}")
        private String buildNumber;
        private EovService eovService;

        @Autowired
        public DemoController(DemoService demoService, EovService eovService) {
            this.demoService = demoService;
            this.eovSqsService = eovSqsService;
        }

        @GetMapping(value = "/version", produces = {"application/json"}, consumes = {
                "application/json"})
        public ResponseEntity getApplicationVersionNumber() {
            String result = environmentName + " " + buildNumber;
            return new ResponseEntity<>(result, HttpStatus.OK);
        }
    }

Below is what I receive in my console for mockServletResponse. The controller class is starting as expected but the mockMvc is receiving 404 response for all the requests.
