java socket.close_java – Socket.close()在Socket.connect()期间无效

使用Windows上的默认套接字实现,我无法找到任何有效的方法来停止Socket.connect(). This answer表明Thread.interrupt()不起作用,但Socket.close()会.但是,在我的审判中,后者也没有用.

我的目标是快速,干净地终止应用程序(即在套接字终止后需要完成清理工作).我不想在Socket.connect()中使用超时,因为可以在合理的超时到期之前终止进程.

import java.net.InetSocketAddress;

import java.net.Socket;

public class ComTest {

static Socket s;

static Thread t;

public static void main(String[] args) throws Exception {

s = new Socket();

InetSocketAddress addr = new InetSocketAddress("10.1.1.1",11);

p(addr);

t = Thread.currentThread();

(new Thread() {

@Override

public void run() {

try {

sleep(4000);

p("Closing...");

s.close();

p("Closed");

t.interrupt();

p("Interrupted");

} catch (Exception e) {

e.printStackTrace();

}

}

}).start();

s.connect(addr);

}

static void p(Object o) {

System.out.println(o);

}

}

/10.1.1.1:11

Closing...

Closed

Interrupted
