swagger无法识别api描述

我假设 docket 这样地

@Bean
public Docket api() {
    return new Docket(DocumentationType.SWAGGER_2)
        .select()
        .apis(RequestHandlerSelectors.basePackage("com.config.internal"))
        .paths(Predicates.or(PathSelectors.ant("/api**/**")))
        .build();
}

我创建了一组存根端点来模拟 /login 或 /oauth .

@Api("Authentication")
@RequestMapping("/api")
public interface LoginEndpointApi {

    @ApiOperation(value = "Github SSO endpoint", notes = "Endpoint for Github SSO authentication")
    @ApiResponses({
        @ApiResponse(code = 200, message = "HTML page of main application")
    })
    @GetMapping("/oauth/github")
    default void oauthGithub() {
        throw new UnsupportedOperationException();
    }

    @ApiOperation(value = "Get CSRF token", notes = "Returns current CSRF token")
    @ApiResponses({
        @ApiResponse(code = 200, message = "CSRF token response", response = String.class,
            examples = @Example({@ExampleProperty(value = "015275eb-293d-4ce9-ba07-ff5e1c348092")}))
    })
    @GetMapping("/csrf-token")
    default void csrfToken() {
        throw new UnsupportedOperationException();
    }

    @ApiOperation(value = "Login endpoint", notes = "Login endpoint for authorization")
    @ApiResponses({
        @ApiResponse(code = 200, message = "Successful authentication")
    })
    @PostMapping("/login")
    default void login(
            @ApiParam(required = true, name = "login", value = "login body")
            @RequestBody LoginRequest loginRequest) {
        throw new UnsupportedOperationException();
    }
}

但它认不出来。它位于同一位置 com.config.internal 按我说的打包。

但是页面 swagger ui 是空的 No operations defined in spec!

怎么了?
