Drools：drl 文件变量

Question

下面是我的 class :

    public class NumberDetails {

        private String a ; 
        private String b;
        private String c;
        private String status;

        private String result;

         // getters and setters
        }

初始化值状态：302，a = "A"，b="2"

我必须应用逻辑：

if(status=302){
    result = a+b; 

}

如何在.drl文件中写这个？

rule "302 case"
when 
    numberObject: NumberDetails(status==302)
then

    numberObject.setResult(numberObject(a)+numberObject(b)); // I know this is wrong but how to write it ?
end

Answer 1

您可以使用 getter and setter 方法获取 drl file 中的值。例如，您可以将规则写为：

rule "302 case"
when 
    numberObject: NumberDetails(status==302)
then

    numberObject.setResult(numberObject.getA()+numberObject.getB());
end
