我有以下课程：

public class SomeAssebler {

    private EnrichedRequest assembleBasicEnrichedRequest(BasicRequest request) {
        EnrichedRequest enrichedRequest = new EnrichedRequest();
        if (request != null) {
            enrichedRequest.setId(request.getId());
            enrichedRequest.setDate(request.getDate());
            enrichedRequest.setParam(request.getParam());
        }
        return enrichedRequest;
    }

    private static EnrichedRequest assembleGeoDataEnrichedRequest(EnrichedRequest request, GeoData geoData) {
        EnrichedRequest geoEnrichedRequest = Optional.ofNullable(request).orElse(new EnrichedRequest());
        if (geoData != null) {
            geoEnrichedRequest.setCity(geoData.getCity());
            geoEnrichedRequest.setCountryCode(geoData.getCountryCode());
        }
        return geoEnrichedRequest;
    }

    private static EnrichedRequest assembleUserAgentEnrichedRequest(EnrichedRequest request, UserAgentData userAgentData) {
        EnrichedRequest userAgentEnrichedRequest = Optional.ofNullable(request).orElse(new EnrichedRequest());
        if (userAgentData != null) {
            userAgentEnrichedRequest.setBrowser(userAgentData.getBrowserCode());
            userAgentEnrichedRequest.setOperatingSystem(userAgentData.getOsCode());
            userAgentEnrichedRequest.setManufacturer(userAgentData.getBrand());
        }
    }

    public static EnrichedRequest assembleEnrichedRequest(BasicRequest request, GeoData geoData, UserAgentData userAgentData) {
        EnrichedRequest enrichedRequest = assembleBasicEnrichedRequest(request);
        enrichedRequest = assembleGeoDataEnrichedRequest(enrichedRequest, geoData);
        enrichedRequest = assembleUserAgentEnrichedRequest(enrichedRequest, userAgentData);
        return enrichedRequest;
    }
}

它在不同的变压器中被称为：在geodatatransformer中

new KeyValue<>(key, assembleEnrichedRequest(basicRequest, geoData, null))

在useragenttransformer中：

new KeyValue<>(key, assembleEnrichedRequest(enrichedRequest, null, userAgent))

如果更多的“丰富”将被添加到未来这可能会变得非常丑陋。有人知道我怎么能设计得更好吗？我想到了建设者的设计模式，但我不确定。
