在上一节中我们实现了根据流量信息过滤的代码,但是我们的条件有可能是多条件一起传给我们的检索服务的,本节我们继续实现根据推广单元的三个维度条件的过滤。
在SearchImpl类中添加过滤方法
public class SearchImpl implements ISearch { @Override public SearchResponse fetchAds(SearchRequest request) { ... // 根据三个维度过滤 if (featureRelation == FeatureRelation.AND) { filterKeywordFeature(adUnitIdSet, keywordFeature); filterHobbyFeature(adUnitIdSet, hobbyFeatrue); filterDistrictFeature(adUnitIdSet, districtFeature); targetUnitIdSet = adUnitIdSet; } else { getOrRelationUnitIds(adUnitIdSet, keywordFeature, hobbyFeatrue, districtFeature); } } return null; }
定义三个方法实现过滤
/** * 获取三个维度各自满足时的广告id */ private SetgetOrRelationUnitIds(Set adUnitIdsSet, KeywordFeature keywordFeature, HobbyFeatrue hobbyFeatrue, DistrictFeature districtFeature) { if (CollectionUtils.isEmpty(adUnitIdsSet)) return Collections.EMPTY_SET; // 我们在处理的时候,需要对副本进行处理,大家可以考虑一下为什么需要这么做? Set keywordUnitIdSet = new HashSet<>(adUnitIdsSet); Set hobbyUnitIdSet = new HashSet<>(adUnitIdsSet); Set districtUnitIdSet = new HashSet<>(adUnitIdsSet); filterKeywordFeature(keywordUnitIdSet, keywordFeature); filterHobbyFeature(hobbyUnitIdSet, hobbyFeatrue); filterDistrictFeature(districtUnitIdSet, districtFeature); // 返回它们的并集 return new HashSet<>( CollectionUtils.union( CollectionUtils.union(keywordUnitIdSet, hobbyUnitIdSet), districtUnitIdSet ) ); } /** * 根据传递的关键词过滤 */ private void filterKeywordFeature(Collection adUnitIds, KeywordFeature keywordFeature) { if (CollectionUtils.isEmpty(adUnitIds)) return; if (CollectionUtils.isNotEmpty(keywordFeature.getKeywords())) { // 如果存在需要过滤的关键词,查找索引实例对象进行过滤处理 CollectionUtils.filter( adUnitIds, adUnitId -> IndexDataTableUtils.of(UnitKeywordIndexAwareImpl.class) .match(adUnitId, keywordFeature.getKeywords()) ); } } /** * 根据传递的兴趣信息过滤 */ private void filterHobbyFeature(Collection adUnitIds, HobbyFeatrue hobbyFeatrue) { if (CollectionUtils.isEmpty(adUnitIds)) return; // 如果存在需要过滤的兴趣,查找索引实例对象进行过滤处理 if (CollectionUtils.isNotEmpty(hobbyFeatrue.getHobbys())) { CollectionUtils.filter( adUnitIds, adUnitId -> IndexDataTableUtils.of(UnitHobbyIndexAwareImpl.class) .match(adUnitId, hobbyFeatrue.getHobbys()) ); } } /** * 根据传递的地域信息过滤 */ private void filterDistrictFeature(Collection adUnitIds, DistrictFeature districtFeature) { if (CollectionUtils.isEmpty(adUnitIds)) return; // 如果存在需要过滤的地域信息,查找索引实例对象进行过滤处理 if (CollectionUtils.isNotEmpty(districtFeature.getProvinceAndCities())) { CollectionUtils.filter( adUnitIds, adUnitId -> { return IndexDataTableUtils.of(UnitDistrictIndexAwareImpl.class) .match(adUnitId, districtFeature.getProvinceAndCities()); } ); } }
根据推广单元id获取推广创意
我们知道,推广单元和推广创意的关系是多对多,从上文我们查询到了推广单元ids,接下来我们实现根据推广单元id获取推广创意的代码,let's code.
首先,我们需要在com.sxzhongf.ad.index.creative_relation_unit.CreativeRelationUnitIndexAwareImpl 关联索引中查到推广创意的ids
/** * 通过推广单元id获取推广创意id */ public ListselectAdCreativeIds(List unitIndexObjects) { if (CollectionUtils.isEmpty(unitIndexObjects)) return Collections.emptyList(); //获取要返回的广告创意ids List result = new ArrayList<>(); for (AdUnitIndexObject unitIndexObject : unitIndexObjects) { //根据推广单元id获取推广创意 Set adCreativeIds = unitRelationCreativeMap.get(unitIndexObject.getUnitId()); if (CollectionUtils.isNotEmpty(adCreativeIds)) result.addAll(adCreativeIds); } return result; }
然后得到了推广创意的id list后,我们在创意索引实现类com.sxzhongf.ad.index.creative.CreativeIndexAwareImpl中定义根据ids查询创意的方法。
/** * 根据ids获取创意list */ public ListfindAllByIds(Collection ids) { if (CollectionUtils.isEmpty(ids)) return Collections.emptyList(); List result = new ArrayList<>(); for (Long id : ids) { CreativeIndexObject object = get(id); if (null != object) result.add(object); } return result; }
自此,我们已经得到了想要的推广单元和推广创意,因为推广单元包含了推广计划,所以我们想要的数据已经全部可以获取到了,接下来,我们还得过滤一次当前我们查询到的数据的状态,因为有的数据,我们可能已经进行过逻辑删除了,因此还需要判断获取的数据是否有效。在SearchImpl类中实现。
/** * 根据状态信息过滤数据 */ private void filterAdUnitAndPlanStatus(ListunitIndexObjects, CommonStatus status) { if (CollectionUtils.isEmpty(unitIndexObjects)) return; //同时判断推广单元和推广计划的状态 CollectionUtils.filter( unitIndexObjects, unitIndexObject -> unitIndexObject.getUnitStatus().equals(status.getStatus()) && unitIndexObject.getAdPlanIndexObject().getPlanStatus().equals(status.getStatus()) ); }
在SearchImpl中我们实现广告创意的查询.
... //获取 推广计划 对象list ListunitIndexObjects = IndexDataTableUtils.of(AdUnitIndexAwareImpl.class).fetch(adUnitIdSet); //根据状态过滤数据 filterAdUnitAndPlanStatus(unitIndexObjects, CommonStatus.VALID); //获取 推广创意 id list List creativeIds = IndexDataTableUtils.of(CreativeRelationUnitIndexAwareImpl.class) .selectAdCreativeIds(unitIndexObjects); //根据 推广创意ids获取推广创意 List creativeIndexObjects = IndexDataTableUtils.of(CreativeIndexAwareImpl.class) ...
根据广告位adslot 实现对创意数据的过滤
因为我们的广告位是有不同的大小,不同的类型,因此,我们在获取到所有符合我们查询维度以及流量类型的条件后,还需要针对不同的广告位来展示不同的广告创意信息。
/** * 根据广告位类型以及参数获取展示的合适广告信息 * * @param creativeIndexObjects 所有广告创意 * @param width 广告位width * @param height 广告位height */ private void filterCreativeByAdSlot(ListcreativeIndexObjects, Integer width, Integer height, List type) { if (CollectionUtils.isEmpty(creativeIndexObjects)) return; CollectionUtils.filter( creativeIndexObjects, creative -> { //审核状态必须是通过 return creative.getAuditStatus().equals(CommonStatus.VALID.getStatus()) && creative.getWidth().equals(width) && creative.getHeight().equals(height) && type.contains(creative.getType()); } ); }
组建搜索返回对象
正常业务场景中,同一个广告位可以展示多个广告信息,也可以只展示一个广告信息,这个需要根据具体的业务场景来做不同的处理,本次为了演示方便,会从返回的创意列表中随机选择一个创意广告信息进行展示,当然大家也可以根据业务类型,设置不同的优先级或者权重值来进行广告选择。
/** * 从创意列表中随机获取一条创意广告返回出去 * * @param creativeIndexObjects 创意广告list */ private ListbuildCreativeResponse(List creativeIndexObjects) { if (CollectionUtils.isEmpty(creativeIndexObjects)) return Collections.EMPTY_LIST; //随机获取一个广告创意,也可以实现优先级排序,也可以根据权重值等等,具体根据业务 CreativeIndexObject randomObject = creativeIndexObjects.get( Math.abs(new Random().nextInt()) % creativeIndexObjects.size() ); //List result = new ArrayList<>(); //result.add(SearchResponse.convert(randomObject)); return Collections.singletonList( SearchResponse.convert(randomObject) ); }
完整的请求过滤实现方法:
@Service @Slf4j public class SearchImpl implements ISearch { @Override public SearchResponse fetchAds(SearchRequest request) { //获取请求广告位信息 ListadSlotList = request.getRequestInfo().getAdSlots(); //获取三个Feature信息 KeywordFeature keywordFeature = request.getFeatureInfo().getKeywordFeature(); HobbyFeatrue hobbyFeatrue = request.getFeatureInfo().getHobbyFeatrue(); DistrictFeature districtFeature = request.getFeatureInfo().getDistrictFeature(); //Feature关系 FeatureRelation featureRelation = request.getFeatureInfo().getRelation(); //构造响应对象 SearchResponse response = new SearchResponse(); Map > adSlotRelationAds = response.getAdSlotRelationAds(); for (AdSlot adSlot : adSlotList) { Set targetUnitIdSet; //根据流量类型从缓存中获取 初始 广告信息 Set adUnitIdSet = IndexDataTableUtils.of( AdUnitIndexAwareImpl.class ).match(adSlot.getPositionType()); // 根据三个维度过滤 if (featureRelation == FeatureRelation.AND) { filterKeywordFeature(adUnitIdSet, keywordFeature); filterHobbyFeature(adUnitIdSet, hobbyFeatrue); filterDistrictFeature(adUnitIdSet, districtFeature); targetUnitIdSet = adUnitIdSet; } else { targetUnitIdSet = getOrRelationUnitIds(adUnitIdSet, keywordFeature, hobbyFeatrue, districtFeature); } //获取 推广计划 对象list List unitIndexObjects = IndexDataTableUtils.of(AdUnitIndexAwareImpl.class) .fetch(targetUnitIdSet); //根据状态过滤数据 filterAdUnitAndPlanStatus(unitIndexObjects, CommonStatus.VALID); //获取 推广创意 id list List creativeIds = IndexDataTableUtils.of(CreativeRelationUnitIndexAwareImpl.class) .selectAdCreativeIds(unitIndexObjects); //根据 推广创意ids获取推广创意 List creativeIndexObjects = IndexDataTableUtils.of(CreativeIndexAwareImpl.class) .fetch(creativeIds); //根据 广告位adslot 实现对创意数据的过滤 filterCreativeByAdSlot(creativeIndexObjects, adSlot.getWidth(), adSlot.getHeight(), adSlot.getType()); //一个广告位可以展示多个广告,也可以仅展示一个广告,具体根据业务来定 adSlotRelationAds.put( adSlot.getAdSlotCode(), buildCreativeResponse(creativeIndexObjects) ); } return response; } ...
检索服务对外提供
暴露API接口
上文中,我们实现了检索服务的核心逻辑,接下来,我们需要对外暴露我们的广告检索服务接口,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); }
实现API网关配置
zuul: routes: sponsor: #在路由中自定义服务路由名称 path: /ad-sponsor/** serviceId: mscx-ad-sponsor #微服务name strip-prefix: false search: #在路由中自定义服务路由名称 path: /ad-search/** serviceId: mscx-ad-search #微服务name strip-prefix: false prefix: /gateway/api strip-prefix: true #不对 prefix: /gateway/api 设置的路径进行截取,默认转发会截取掉配置的前缀
以上就是本次分享的全部知识点内容,感谢大家对创新互联的支持
