Drools集合迭代

这条规则怎么了

rule "Organization Employee Rule"
    when

        $company: CompanyFact( $emp: /employeeList{organizationName== "XYZ"})

    then
        System.out.println("Employee in organization" +$emp);
end

我在尝试运行此规则时遇到此错误

rule "Organization Employee Rule"
    when

        $company: CompanyFact( $emp: /employeeList{organizationName== "XYZ"})

    then
        System.out.println("Employee in organization" +$emp);
end

[ERR 102]第23:44行规则组织员工规则中的输入“{”不匹配

CompanyFact有雇员列表，雇员有字符串组织名称。

如果您使用的是Drools 7.x，则它们是

尝试使用方括号而不是花括号：

rule "Organization Employee Rule"
when
    $company: CompanyFact( $emp: /employeeList[organizationName== "XYZ"])
then
    System.out.println("Employee in organization" +$emp);
end

希望有帮助
