在下面的代码中,我有一个javascript运行在与主要一个单独的线程中.该脚本是一个无限循环,因此它需要以某种方式终止.怎么样？

在脚本开始运行后调用.cancel()不起作用.但是如果我在线程初始化之后调用.cancel(),它将终止它(注释掉的行).

package testscriptterminate;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

import java.util.Timer;
import java.util.TimerTask;

public class TestScriptTerminate extends TimerTask{

    private ExecutorService threads;
    private Future runScript;

    private Timer t;

    public TestScriptTerminate(){
        t = new Timer();
        t.schedule(this, 6000); //let the script run for a while before attempt to cancel

        threads = Executors.newFixedThreadPool(1);
        runScript = threads.submit(new ScriptExec());

        //runScript.cancel(true); //will cancel here, before the script had a change to run, but useless, i want to cancel at any …
