在调用具有完全未来的外部请购单时,我可以使用Feign拦截器吗?

我正试图使用foreign拦截器来处理我使用completable future调用的foreign请购单,但ServletRequestAttributes只返回null。

public class FeignInterceptor implements RequestInterceptor  {

    @Override
    public void apply(RequestTemplate requestTemplate) {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        String bearerToken = request.getHeader(AUTHORIZATION);
        requestTemplate.header(AUTHORIZATION, bearerToken);
    }
}

    public Object searchObject() {
        Object[] listFutures;
        try {
            listFutures = Stream.of(getObjectFuture1(), getObjectFuture2(), getObjectFuture3())
                    .map(CompletableFuture::join)
                    .toArray(Object[]::new);
        } catch(Exception e) {
            throw e.getCause();
        }

        // Rest of the code

        return listFutures[0];
    }
    
    private CompletableFuture<Object> getObjectFuture1() {
        return CompletableFuture.supplyAsync(() -> feignClient.detailObject(null));
    }
    
    private CompletableFuture<Object> getObjectFuture2() {
        return CompletableFuture.supplyAsync(() -> feignClient.listObject(true));
    }
    
    private CompletableFuture<Object> getObjectFuture3() {
        return CompletableFuture.supplyAsync(() -> feignClient.listObject(true));
    }

我找了很长时间的anwser,但找不到。
