根据三个维度继续过滤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。
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;
}/**
* 获取三个维度各自满足时的广告id
*/
private Set<Long> getOrRelationUnitIds(Set<Long> 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<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<Long> 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<Long> 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<Long> 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());
}
);
}
}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 List<Long> selectAdCreativeIds(List<AdUnitIndexObject> unitIndexObjects) {
if (CollectionUtils.isEmpty(unitIndexObjects)) return Collections.emptyList();
//获取要返回的广告创意ids
List<Long> result = new ArrayList<>();
for (AdUnitIndexObject unitIndexObject : unitIndexObjects) {
//根据推广单元id获取推广创意
Set<Long> 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 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(List<AdUnitIndexObject> unitIndexObjects, 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
List<AdUnitIndexObject> unitIndexObjects = 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<Long> creativeIds = IndexDataTableUtils.of(CreativeRelationUnitIndexAwareImpl.class)
.selectAdCreativeIds(unitIndexObjects);
//根据 推广创意ids获取推广创意
List<CreativeIndexObject> creativeIndexObjects = IndexDataTableUtils.of(CreativeIndexAwareImpl.class)
...
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(List<CreativeIndexObject> creativeIndexObjects,
Integer width,
Integer height,
List<Integer> 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());
}
);
}/**
* 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 List<SearchResponse.Creative> buildCreativeResponse(List<CreativeIndexObject> 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<SearchResponse.Creative> 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
List<AdSlot> adSlotList = 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<String, List<SearchResponse.Creative>> adSlotRelationAds = response.getAdSlotRelationAds();
for (AdSlot adSlot : adSlotList) {
Set<Long> targetUnitIdSet;
//根据流量类型从缓存中获取 初始 广告信息
Set<Long> 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<AdUnitIndexObject> 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<Long> creativeIds = IndexDataTableUtils.of(CreativeRelationUnitIndexAwareImpl.class)
.selectAdCreativeIds(unitIndexObjects);
//根据 推广创意ids获取推广创意
List<CreativeIndexObject> 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;
}
...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
