根據三個維度繼續過濾
在上一節中我們實現了根據流量資訊過濾的程式碼,但是我們的條件有可能是多條件一起傳給我們的檢索服務的,本節我們繼續實現根據推廣單元的三個維度條件的過濾。
- 在
SearchImpl
類中新增過濾方法
public class SearchImpl implements ISearch {
@Override
public SearchResponse fetchAds(SearchRequest request) {
...
// 根據三個維度過濾
if (featureRelation == FeatureRelation.AND) {
filterKeywordFeature(adUnitIdSet, keywordFeature);
filterHobbyFeature(adUnitIdSet, hobbyFeatrue);
filterDistrictFeature(adUnitIdSet, districtFeature);
targetUnitIdSet = adUnitIdSet;
} else {
getOrRelationUnitIds(adUnitIdSet, keywordFeature, hobbyFeatrue, districtFeature);
}
}
return null;
}
- 定義三個方法實現過濾
/**
* 獲取三個維度各自滿足時的廣告id
*/
private Set<Long> getOrRelationUnitIds(Set<Long> adUnitIdsSet,
KeywordFeature keywordFeature,
HobbyFeatrue hobbyFeatrue,
DistrictFeature districtFeature) {
if (CollectionUtils.isEmpty(adUnitIdsSet)) return Collections.EMPTY_SET;
// 我們在處理的時候,需要對副本進行處理,大家可以考慮一下為什麼需要這麼做?
Set<Long> keywordUnitIdSet = new HashSet<>(adUnitIdsSet);
Set<Long> hobbyUnitIdSet = new HashSet<>(adUnitIdsSet);
Set<Long> districtUnitIdSet = new HashSet<>(adUnitIdsSet);
filterKeywordFeature(keywordUnitIdSet, keywordFeature);
filterHobbyFeature(hobbyUnitIdSet, hobbyFeatrue);
filterDistrictFeature(districtUnitIdSet, districtFeature);
// 返回它們的並集
return new HashSet<>(
CollectionUtils.union(
CollectionUtils.union(keywordUnitIdSet, hobbyUnitIdSet),
districtUnitIdSet
)
);
}
/**
* 根據傳遞的關鍵詞過濾
*/
private void filterKeywordFeature(Collection<Long> adUnitIds, KeywordFeature keywordFeature) {
if (CollectionUtils.isEmpty(adUnitIds)) return;
if (CollectionUtils.isNotEmpty(keywordFeature.getKeywords())) {
// 如果存在需要過濾的關鍵詞,查詢索引例項物件進行過濾處理
CollectionUtils.filter(
adUnitIds,
adUnitId -> IndexDataTableUtils.of(UnitKeywordIndexAwareImpl.class)
.match(adUnitId, keywordFeature.getKeywords())
);
}
}
/**
* 根據傳遞的興趣資訊過濾
*/
private void filterHobbyFeature(Collection<Long> adUnitIds, HobbyFeatrue hobbyFeatrue) {
if (CollectionUtils.isEmpty(adUnitIds)) return;
// 如果存在需要過濾的興趣,查詢索引例項物件進行過濾處理
if (CollectionUtils.isNotEmpty(hobbyFeatrue.getHobbys())) {
CollectionUtils.filter(
adUnitIds,
adUnitId -> IndexDataTableUtils.of(UnitHobbyIndexAwareImpl.class)
.match(adUnitId, hobbyFeatrue.getHobbys())
);
}
}
/**
* 根據傳遞的地域資訊過濾
*/
private void filterDistrictFeature(Collection<Long> adUnitIds, DistrictFeature districtFeature) {
if (CollectionUtils.isEmpty(adUnitIds)) return;
// 如果存在需要過濾的地域資訊,查詢索引例項物件進行過濾處理
if (CollectionUtils.isNotEmpty(districtFeature.getProvinceAndCities())) {
CollectionUtils.filter(
adUnitIds,
adUnitId -> {
return IndexDataTableUtils.of(UnitDistrictIndexAwareImpl.class)
.match(adUnitId, districtFeature.getProvinceAndCities());
}
);
}
}
根據推廣單元id獲取推廣創意
我們知道,推廣單元和推廣創意的關係是多對多,從上文我們查詢到了推廣單元ids,接下來我們實現根據推廣單元id獲取推廣創意的程式碼,let's code.
首先,我們需要在com.sxzhongf.ad.index.creative_relation_unit.CreativeRelationUnitIndexAwareImpl
關聯索引中查到推廣創意的ids
/**
* 通過推廣單元id獲取推廣創意id
*/
public List<Long> selectAdCreativeIds(List<AdUnitIndexObject> unitIndexObjects) {
if (CollectionUtils.isEmpty(unitIndexObjects)) return Collections.emptyList();
//獲取要返回的廣告創意ids
List<Long> result = new ArrayList<>();
for (AdUnitIndexObject unitIndexObject : unitIndexObjects) {
//根據推廣單元id獲取推廣創意
Set<Long> adCreativeIds = unitRelationCreativeMap.get(unitIndexObject.getUnitId());
if (CollectionUtils.isNotEmpty(adCreativeIds)) result.addAll(adCreativeIds);
}
return result;
}
然後得到了推廣創意的id list後,我們在創意索引實現類com.sxzhongf.ad.index.creative.CreativeIndexAwareImpl
中定義根據ids查詢創意的方法。
/**
* 根據ids獲取創意list
*/
public List<CreativeIndexObject> findAllByIds(Collection<Long> ids) {
if (CollectionUtils.isEmpty(ids)) return Collections.emptyList();
List<CreativeIndexObject> result = new ArrayList<>();
for (Long id : ids) {
CreativeIndexObject object = get(id);
if (null != object)
result.add(object);
}
return result;
}
自此,我們已經得到了想要的推廣單元和推廣創意,因為推廣單元包含了推廣計劃,所以我們想要的資料已經全部可以獲取到了,接下來,我們還得過濾一次當前我們查詢到的資料的狀態,因為有的資料,我們可能已經進行過邏輯刪除了,因此還需要判斷獲取的資料是否有效。在SearchImpl
類中實現。
/**
* 根據狀態資訊過濾資料
*/
private void filterAdUnitAndPlanStatus(List<AdUnitIndexObject> unitIndexObjects, CommonStatus status) {
if (CollectionUtils.isEmpty(unitIndexObjects)) return;
//同時判斷推廣單元和推廣計劃的狀態
CollectionUtils.filter(
unitIndexObjects,
unitIndexObject -> unitIndexObject.getUnitStatus().equals(status.getStatus()) &&
unitIndexObject.getAdPlanIndexObject().getPlanStatus().equals(status.getStatus())
);
}
在SearchImpl
中我們實現廣告創意的查詢.
...
//獲取 推廣計劃 物件list
List<AdUnitIndexObject> unitIndexObjects = IndexDataTableUtils.of(AdUnitIndexAwareImpl.class).fetch(adUnitIdSet);
//根據狀態過濾資料
filterAdUnitAndPlanStatus(unitIndexObjects, CommonStatus.VALID);
//獲取 推廣創意 id list
List<Long> creativeIds = IndexDataTableUtils.of(CreativeRelationUnitIndexAwareImpl.class)
.selectAdCreativeIds(unitIndexObjects);
//根據 推廣創意ids獲取推廣創意
List<CreativeIndexObject> creativeIndexObjects = IndexDataTableUtils.of(CreativeIndexAwareImpl.class)
...
根據廣告位adslot 實現對創意資料的過濾
因為我們的廣告位是有不同的大小,不同的型別,因此,我們在獲取到所有符合我們查詢維度以及流量型別的條件後,還需要針對不同的廣告位來展示不同的廣告創意資訊。
/**
* 根據廣告位型別以及引數獲取展示的合適廣告資訊
*
* @param creativeIndexObjects 所有廣告創意
* @param width 廣告位width
* @param height 廣告位height
*/
private void filterCreativeByAdSlot(List<CreativeIndexObject> creativeIndexObjects,
Integer width,
Integer height,
List<Integer> type) {
if (CollectionUtils.isEmpty(creativeIndexObjects)) return;
CollectionUtils.filter(
creativeIndexObjects,
creative -> {
//稽核狀態必須是通過
return creative.getAuditStatus().equals(CommonStatus.VALID.getStatus())
&& creative.getWidth().equals(width)
&& creative.getHeight().equals(height)
&& type.contains(creative.getType());
}
);
}
- 組建搜尋返回物件
正常業務場景中,同一個廣告位可以展示多個廣告資訊,也可以只展示一個廣告資訊,這個需要根據具體的業務場景來做不同的處理,本次為了演示方便,會從返回的創意列表中隨機選擇一個創意廣告資訊進行展示,當然大家也可以根據業務型別,設定不同的優先順序或者權重值來進行廣告選擇。
/**
* 從創意列表中隨機獲取一條創意廣告返回出去
*
* @param creativeIndexObjects 創意廣告list
*/
private List<SearchResponse.Creative> buildCreativeResponse(List<CreativeIndexObject> creativeIndexObjects) {
if (CollectionUtils.isEmpty(creativeIndexObjects)) return Collections.EMPTY_LIST;
//隨機獲取一個廣告創意,也可以實現優先順序排序,也可以根據權重值等等,具體根據業務
CreativeIndexObject randomObject = creativeIndexObjects.get(
Math.abs(new Random().nextInt()) % creativeIndexObjects.size()
);
//List<SearchResponse.Creative> result = new ArrayList<>();
//result.add(SearchResponse.convert(randomObject));
return Collections.singletonList(
SearchResponse.convert(randomObject)
);
}
完整的請求過濾實現方法:
@Service
@Slf4j
public class SearchImpl implements ISearch {
@Override
public SearchResponse fetchAds(SearchRequest request) {
//獲取請求廣告位資訊
List<AdSlot> adSlotList = request.getRequestInfo().getAdSlots();
//獲取三個Feature資訊
KeywordFeature keywordFeature = request.getFeatureInfo().getKeywordFeature();
HobbyFeatrue hobbyFeatrue = request.getFeatureInfo().getHobbyFeatrue();
DistrictFeature districtFeature = request.getFeatureInfo().getDistrictFeature();
//Feature關係
FeatureRelation featureRelation = request.getFeatureInfo().getRelation();
//構造響應物件
SearchResponse response = new SearchResponse();
Map<String, List<SearchResponse.Creative>> adSlotRelationAds = response.getAdSlotRelationAds();
for (AdSlot adSlot : adSlotList) {
Set<Long> targetUnitIdSet;
//根據流量型別從快取中獲取 初始 廣告資訊
Set<Long> adUnitIdSet = IndexDataTableUtils.of(
AdUnitIndexAwareImpl.class
).match(adSlot.getPositionType());
// 根據三個維度過濾
if (featureRelation == FeatureRelation.AND) {
filterKeywordFeature(adUnitIdSet, keywordFeature);
filterHobbyFeature(adUnitIdSet, hobbyFeatrue);
filterDistrictFeature(adUnitIdSet, districtFeature);
targetUnitIdSet = adUnitIdSet;
} else {
targetUnitIdSet = getOrRelationUnitIds(adUnitIdSet, keywordFeature, hobbyFeatrue, districtFeature);
}
//獲取 推廣計劃 物件list
List<AdUnitIndexObject> unitIndexObjects = IndexDataTableUtils.of(AdUnitIndexAwareImpl.class)
.fetch(targetUnitIdSet);
//根據狀態過濾資料
filterAdUnitAndPlanStatus(unitIndexObjects, CommonStatus.VALID);
//獲取 推廣創意 id list
List<Long> creativeIds = IndexDataTableUtils.of(CreativeRelationUnitIndexAwareImpl.class)
.selectAdCreativeIds(unitIndexObjects);
//根據 推廣創意ids獲取推廣創意
List<CreativeIndexObject> creativeIndexObjects = IndexDataTableUtils.of(CreativeIndexAwareImpl.class)
.fetch(creativeIds);
//根據 廣告位adslot 實現對創意資料的過濾
filterCreativeByAdSlot(creativeIndexObjects, adSlot.getWidth(), adSlot.getHeight(), adSlot.getType());
//一個廣告位可以展示多個廣告,也可以僅展示一個廣告,具體根據業務來定
adSlotRelationAds.put(
adSlot.getAdSlotCode(),
buildCreativeResponse(creativeIndexObjects)
);
}
return response;
}
...
檢索服務對外提供
暴露API介面
上文中,我們實現了檢索服務的核心邏輯,接下來,我們需要對外暴露我們的廣告檢索服務介面,在SearchController
中提供:@PostMapping("/fetchAd") public SearchResponse fetchAdCreative(@RequestBody SearchRequest request) { log.info("ad-serach: fetchAd ->{}", JSON.toJSONString(request)); return search.fetchAds(request); }
實現API閘道器配置
zuul: routes: sponsor: #在路由中自定義服務路由名稱 path: /ad-sponsor/** serviceId: mscx-ad-sponsor #微服務name strip-prefix: false search: #在路由中自定義服務路由名稱 path: /ad-search/** serviceId: mscx-ad-search #微服務name strip-prefix: false prefix: /gateway/api strip-prefix: true #不對 prefix: /gateway/api 設定的路徑進行擷取,預設轉發會擷取掉配置的字首
