以drools验证

Question

这是我的drools验证问题的第二部分。第一部分已经得到解答，我的代码中已经提出了解决方案。 First Part

这是我的java类结构

public class Person {
 List<PersonAddress> personAddress;
 List<FinanceDetails> financeDetails;
}
public enum AddressStatus {
 CURRENT, PREVIOUS;
}
public enum AddressType {
 PHYSICAL, POSTAL;
}
public enum AddressUseType {
 HOME, OFFICE;
}
public class PersonAddress{    
  Address address;
  AddressType type
  AddressStatus status
  AddressUseType useType
  String ownerShipType
  Integer timeAtAddress;        
}
public class Address {
  String city;
  String country;
  String street;
}
public class FinanceDetails {
  String financeItemName;
  BigDecimal itemValue;
}

好的我的问题是，如果financeItemName是＆＃34; Land或Building＆＃34;，如果此用户的地址符合以下条件，我需要验证FinanceDetails实例的itemValue，

AddressStatus == CURRENT

AddressType == PHYSICAL

AddressUseType == HOME

ownerShipType ==＆＃34;拥有＆＃34;

Drools版本5.5.0.Final

Java 1.7

可以使用

功能

需要示例流氓规则语法。谢谢

Answer 1

添加了itemValue测试，如某些评论中所示

rule "land-orbuilding..."
when
  Peson( $financeDetails: financeDetails, $personAddress: personAddress )
  FinanceDetails( financeItemName == "Land or Building", itemValue == null || itemValue == 0 ) from $financeDetails
  PersonAddress( status == AddressStatus.CURRENT,
                 type == AddressType.PHYSICAL,
                 useType == AddressUseType.HOME,
                 ownerShipType == "Own" ) from $personAddress
then
  //...
end

阅读一些文档怎么样？这非常像“第一部分”，只是一个微小的变化。

Answer 2

rule "Check Details"
when
  details:FinanceDetails  (itemValue == 'LAND' || == 'Building')
  address:PersonAddress(status == AddressStatus.CURRENT,
                 type == AddressType.PHYSICAL,
                 useType == AddressUseType.HOME,
                 ownerShipType == "Own" )
then
  modify(details){itemValue=//set your value};
end
