java - 流口水返回最低显着性规则

Question

我遇到了匹配多个规则并获取显着性最低的规则的问题。这是源文件。

package HotelAnalyticsLuxuryPromotions 
#generated from Decision Table
import com.mmt.analytics.hotel.promotions.drools.HotelPromotionsDroolsPojo;
import com.mmt.analytics.hotel.promotions.drools.HotelPromotionsDroolRules;
#From row number: 11
rule "for Luxury Hotel Promotions_11"
    salience 9
    when
        fact: HotelPromotionsDroolsPojo(
  eval(HotelPromotionsDroolRules.checkHotelId(fact,"12345")),
  eval(HotelPromotionsDroolRules.checkRsq(fact,"*")),
  eval(HotelPromotionsDroolRules.checkValidCheckInCheckOut(fact,"*")), 
  eval(HotelPromotionsDroolRules.checkLoggedStatus(fact,"*")))
        eval(HotelPromotionsDroolRules.checkActiveStatus(fact,"1"))
    then
        fact.setPackageName("Pack 2");
        fact.setRatePlanCode("ABC 2");
        fact.setTariffUrl("TariffUrl");
        fact.setClickUrl("ClickUrl");
        fact.setInclusionText("InclusionText");
end

#From row number: 12
rule "for Luxury Hotel Promotions_12"
    salience 10
    when
        fact: HotelPromotionsDroolsPojo(
  eval(HotelPromotionsDroolRules.checkHotelId(fact,"12345")), 
  eval(HotelPromotionsDroolRules.checkRsq(fact,"*")), 
  eval(HotelPromotionsDroolRules.checkValidCheckInCheckOut(fact,"*")), 
  eval(HotelPromotionsDroolRules.checkLoggedStatus(fact,"*")))
        eval(HotelPromotionsDroolRules.checkActiveStatus(fact,"1"))
    then
        fact.setPackageName("Pack 1");
        fact.setRatePlanCode("ABC 1");
        fact.setTariffUrl("TariffUrl");
        fact.setClickUrl("ClickUrl");
        fact.setInclusionText("InclusionText");
end

#From row number: 14
rule "for Luxury Hotel Promotions_14"
    salience 5
    when
        fact:HotelPromotionsDroolsPojo(
  eval(HotelPromotionsDroolRules.checkHotelId(fact,"12345")), 
  eval(HotelPromotionsDroolRules.checkRsq(fact,"*")), 
  eval(HotelPromotionsDroolRules.checkValidCheckInCheckOut(fact,"*")), 
  eval(HotelPromotionsDroolRules.checkLoggedStatus(fact,"*")))
        eval(HotelPromotionsDroolRules.checkActiveStatus(fact,"1"))
    then
        fact.setPackageName("Pack 3");
        fact.setRatePlanCode("ABC 3");
        fact.setTariffUrl("TariffUrl");
        fact.setClickUrl("ClickUrl");
        fact.setInclusionText("InclusionText");
end

我认为必须返回具有最高优先级的规则，但我得到的恰恰相反。

下面是规则引擎的代码

   StatelessKnowledgeSession kSession = promotionsDroolManager.getStatelessSession();
        kSession.execute(droolsPojo);

我正在使用这些 Drool 配置属性

promotions.drools.agent.scan.resources=true
promotions.drools.agent.scan.directories=true
promotions.drools.resource.scanner.interval=1800
promotions.drools.agent.monitor.change.set.events=true
promotions.drools.knowledge.agent.name=Promotions_Knowledge_agent
promotions.drools.base.knowledge.agent.change.set.path=promotions.xml

请。建议

如果您使用 kie workbench 进行规则建模，则可以添加显着性属性列，如下所示。这将确保表中的最后一条规则具有最高优先级。
