需要帮助，了解口水中的PHREAK算法和规则激活7

标签： drools

我们正在将Drools实现从5.4迁移到7.20。我创建了一个基本的单元测试，以尝试使用新的PHREAK算法确定drools 7中的决策。

除了显着性，无循环性之外，我已经验证了当多个规则与LHS上的条件匹配时，文件中的后一个规则将具有优先权。但是，在这种情况下，我不能遵循更通用的规则，也找不到能清楚说明正在发生什么情况的文档。

此测试在具有junit 4.11和drools 7.15.0.Final的Java 8中运行。我尝试了7.20，结果相同。

有问题的2条规则将简单地将一个姓氏取为一个人，并为名字设置一个新值。如下面的规则所示，最终值是将firstName设置为“ NEW”。

rule "rule1"
    ruleflow-group "rfg1"
    when
        $person : BFEnrollmentPerson(firstName != null)
        $name : TransitoryElement(value == "Orig") from $person.getFirstName()
    then
        System.out.println("1 Fired: " + $person.getFirstName().getValue());
        $person.getFirstName().setValue("New");
    end

rule "rule2"
    ruleflow-group "rfg1"
    when
        $person : BFEnrollmentPerson()
        $name : TransitoryElement(value == "Orig") from $person.getFirstName()
    then
         $person.getFirstName().setValue("New2");
         System.out.println("2 Fired: " + $person.getFirstName().getValue());
    end

我可以通过听众看到第二条规则从未激活过。但是，如果我将“ rule2”更改为更具体，例如查找“ rule1”设置的值或使该规则等效于“ rule1”，则第二个规则将被激活并优先。我，其中任何一个都会激活并享有优先权：

rule "rule2"
    ruleflow-group "rfg1"
    when
        $person : BFEnrollmentPerson(firstName != null)
        $name : TransitoryElement(value == "Orig") from $person.getFirstName()
    then
         $person.getFirstName().setValue("New2");
         System.out.println("2 Fired: " + $person.getFirstName().getValue());
    end

或

rule "rule2"
    ruleflow-group "rfg1"
    when
        $person : BFEnrollmentPerson()
        $name : TransitoryElement(value == "New") from $person.getFirstName()
    then
         $person.getFirstName().setValue("New2");
         System.out.println("2 Fired: " + $person.getFirstName().getValue());
    end

1 Fired: Orig
2 Fired: New2
Final person first name value is: New2

我希望在所有这些情况下，“ rule2”将始终处于激活状态，并且最终值将来自“ rule2”，因为它在所有情况下均符合标准。它在规则流中具有默认显着性，并且是文件中的最新显着性。为什么在第一种情况下不考虑“ rule2”？
