java - 在字符串变量中获取CLIPS/Jess输出

我已经在netbeans中将jess与java集成了。我想访问字符串变量中的输出。

当我（运行）.clp文件并提供输入时，它向我显示输出，但是我想以字符串变量获取此输出。我怎样才能做到这一点？？请帮忙。这是我的.clp文件代码。

(deftemplate problem
(multislot name)
(slot symptom))

(deffacts probelms
(probelm (name (create$ "Air filter"  "fuel injector problem" "fuel pressure regualtor"))
    (symptom Black-Smoke))
    )

(defrule reading-input
=>
(printout t "Enter the symptom your car Shows: " )
(assert (var (read))))

(defrule checking-input
(var ?symptom)
(probelm  (symptom ?symptom1)(name $?name1))
(test (eq ?symptom ?symptom1))
 =>
(printout t "Problems can be " $?name1 crlf))

在Java中运行此代码

 public static string path="C:\Users\Taimoor Mirza\Documents\car.CLP";
  Rete r=new Rete();
   r.batch(path);
   r.reset();
   r.run();

运行良好，当我输入Black-Smoke时，这使我在运行exe时可能出现症状。
我想以字符串形式获取这些症状。我如何在String中获得此结果？

最佳答案

设置一个Writer并告诉Jess使用它：

Writer writer = new StringWriter();
rete.addOutputRouter( "t", writer );
// run Jess writing to router "t"
System.out.println( writer.toString() );
