java - 多线程和 Selenium

Question

我试图在不同的 WebChrome 驱动程序 (atcThread[]) 中尽可能快地打开一组链接。我尝试实现 ExecutorService 但意识到线程的初始执行是顺序的。有没有一种方法可以并行打开链接更快。谢谢!

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

public class ATC {
    private ExecutorService executor = Executors.newFixedThreadPool(15);

    public void startThreads() {
        for (int i = 0; i < Captcha.x; i++) {
            executor.execute(new ATCpool(i, Generator.links[i]));
        }
    }

    private final class ATCpool implements Runnable{

        public ATCpool(int x, String link){
            Generator.atcThread[x].get(link);
        }

        @Override
        public void run() {
            // TODO Auto-generated method stub
        }
    }
}

对我来说，你得到这个行为是因为你在你的类 ATCpool 的构造函数中调用方法 get(String url) 而不是调用它到 run 方法将其调用委托(delegate)给您期望的线程池。

只需将类 ATCpool 更改为如下所示:

private final class ATCpool implements Runnable {

    private final int x;
    private final String link;

    ATCpool(int x, String link){
        this.x = x;
        this.link = link;
    }

    @Override
    public void run() {
        // Will be called asynchronously by a thread of the thread pool
        Generator.atcThread[x].get(link);
    }
}
