Spring cloud 查询返回广告创意实例代码

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。

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 Set getOrRelationUnitIds(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 = nehzvAIiw 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 List selectAdCreativeIds(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 List findAllByIds(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(List 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 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 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(List creativeIndexObjects,

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 List buildCreativeResponse(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

List 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

SearchResponsehzvAIi 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;

} ehttp://lse {

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hzvAIi发会截取掉配置的前缀
