嗨，我该如何执行3个可调用函数，这样我就不必等待何时执行另一个进程，在某种程度上，我将不得不等待它们完成，然后才能正确地移动到我的下一行代码？我是这样做的：
我有一个返回值为可调用的函数：

public <T> Callable<List<T>> getDataFromOtherAPI(List<Long> ids, String url, Class<T> tClass){
    WebClient webClient = WebClient.create();

    //NOTE init mapper
    ObjectMapper mapper = new ObjectMapper()
        .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); 
    //NOTE end of init mapper

    CollectionType listType = mapper.getTypeFactory().constructCollectionType(ArrayList.class, tClass);

    List<T> object = webClient.post()
        .uri(url).body(Mono.just(ids), Object.class)
        .retrieve()
        .onStatus(HttpStatus::isError, res -> res.bodyToMono(ExceptionResponse.class)
                .onErrorResume(e -> Mono.error(new ResourceNotFound("Something Happened")))
                .flatMap(errorBody -> Mono.error(new ResourceNotFound(errorBody.getMessage())))
        )
        .bodyToMono(new ParameterizedTypeReference<List<T>>() {})
        .block();

    List<T> mappedClass = mapper.convertValue(object, listType);

    if(mappedClass.size() == 0) {
        throw new ResourceNotFound("Data in Url " + url + " not found");
    }

    return () -> mappedClass;
}

我是这样宣布我的执行官的：

@Autowired
@Qualifier("executor")
private AsyncTaskExecutor execs;

下面是我如何尝试从函数中的另一个api调用：

Future<List<PartnerDto>> initPartners = execs.submit(getDataFromOtherAPI(
            transDeliveryPlanningDtSoDtoPartnerIds, b2b.getPartnerSpecificId(), PartnerDto.class));

Future<List<PartnerShipmentDto>> initPartnerShipments = execs.submit(getDataFromOtherAPI(
            transDeliveryPlanningDtSoDtoPartnerShipmentIds, b2b.getPartnerShipmentSpecificId(), PartnerShipmentDto.class));

Future<List<ProductResponseDto>> initProduct = execs.submit(getDataFromOtherAPI(
            transDeliveryPlanningDtSoDetailDto, b2b.getProductSpecificId(), ProductResponseDto.class));

    //another much process

    //end of another much process

    //i have to hold over here before i continue into my next process to do some for loop :

    for(TransDeliveryPlanningDtSoDto e : d.getTransDeliveryPlanningDtSoDto()) {

         PartnerDto latestPartner = new PartnerDto();
         PartnerShipmentDto latestPartnerShipment = new PartnerShipmentDto();
         TransSalesOrder latestSalesOrder = new TransSalesOrder();

         latestProduct = initProduct.stream().filter(so -> productId.equals(so.getId())).findAny().orElseThrow(() -> new ResourceNotFound("Product " + so.getIs() + " Not Found"));
         latestPartner = initPartners.stream().filter(partner -> partnerId.equals(partner.getId())).findAny().orElseThrow(() -> new ResourceNotFound("Partner " + partnerName + " Not Found"));
         latestPartnerShipment = initPartnerShipments.stream().filter(partnerShipment -> partnerShipmentId.equals(partnerShipment.getId())).findAny().orElseThrow(() -> new ResourceNotFound("PartnerShipment Not Found"));

        }

我必须添加一些东西来保持/等待异步进程正确完成？我该怎么做？
