我有一個從其端點@RestController返回DeferredResult對象的類。在到達這些端點之前，我使用一個@EnableWebSecurity類來設置基本身份驗證。我能夠使用正確的基本身份驗證在本地卷曲這些端點并使其工作。但是，通過 spring 測試測試這些端點會導致此異常：java.lang.ClassCastException: org.springframework.security.web.servletapi.HttpServlet3RequestFactory$SecurityContextAsyncContext 不能轉換為 org.springframework.mock.web.MockAsyncCont我已經嘗試在我的測試類上使用@WebAppConfiguration和@ContextConfiguration(classes = SpringSecurityConfig.class)注釋并設置MockMvc我自己（SpringSecurityConfig只是我實現基本身份驗證的類）。我也試過只使用@SpringBootTestand @AutoConfigureMockMvc。這是我當前的測試課程：@RunWith(SpringRunner.class)@WebAppConfiguration@ContextConfiguration(classes = SpringSecurityConfig.class)public class PushNotificationControllerSpringTest {    @MockBean    BucketDetailsService bucketDetailsService;    @MockBean    NotificationService notificationService;    @Autowired    protected WebApplicationContext wac;    private MockMvc mockMvc;    @Before    public void prepare() {        mockMvc = MockMvcBuilders.webAppContextSetup(wac).apply(springSecurity()).build();    }    @Test    public void testListBulletins() throws Exception {        mockMvc.perform(asyncDispatch(                mockMvc.perform(get("/admin/bulletins").header("Authorization", "Basic YWRtaW46cGFzc3cwcmQ="))                        .andExpect(status().isOk()).andReturn()));    }}這是我的休息控制器：@RestController@RequestMapping("/admin")public class PushNotificationController {    protected static final Logger logger = LoggerFactory.getLogger(PushNotificationController.class);    @Autowired    BucketDetailsService bucketDetailsService;    @GetMapping("/bulletins")    public DeferredResult<List<BulletinDetails>> listBulletins() {        DeferredResult<List<BulletinDetails>> deferredResult = new DeferredResult<>();        logger.debug("Fetching bulletins...");        bucketDetailsService.listBulletins()                .whenComplete((res, ex) -> setResult(deferredResult, res, ex, "List bulletins"));        return deferredResult;    }
