        WebAsyncManager asyncManager = WebAsyncUtils.getAsyncManager(request);

        SecurityContextCallableProcessingInterceptor securityProcessingInterceptor = (SecurityContextCallableProcessingInterceptor) asyncManager
                .getCallableInterceptor(CALLABLE_INTERCEPTOR_KEY);
        if (securityProcessingInterceptor == null) {
            asyncManager.registerCallableInterceptor(CALLABLE_INTERCEPTOR_KEY,
                    new SecurityContextCallableProcessingInterceptor());
        }
