在 Drools 中定位语法错误

Question

我有一个流口水的文件，其中规则 2 总是成立。

rule "R2"
salience 1000

when

((residence status = "US Citizen") || ((residence status = "Lawfully-entered Alien") and (residence duration >= 5))) and (fpl <= 133)
then

Add to Programs List "3"
end

值

residence status is US Citizen
residence status is null 
residence duration is 0
fpl is 278.77

尽管对于指定值，条件为 false ，但为什么它总是进入其中的

。请找到所有文件。

任何人都可以帮助我为什么它是 entring 是 list3 尽管上面提供的数据并不使它有效

Answer 1

查看为您的规则生成的 java 类并查看可能存在的问题也可能会有所帮助。
使用：
-Ddrools.dump.dir=
设置生成代码的路径。

设置规则侦听器并查看事实插入更新和规则触发序列也可能会有所帮助。

另外，您可以尝试将有问题的规则分解为两个没有 DSL 的规则，如下所示以进行调试：

when
FamilyMember(basicInfo.citizenshipStatus == "US Citizen")
Fact(eval(fpl <= 133))

when
FamilyMember(basicInfo.citizenshipStatus == "Lawfully-entered Alien")
FamilyMember(basicInfo.permanentResidenceDuration >= 5)
Fact(eval(fpl <= 133))

希望这会有所帮助。
