java—如何取消从另一个线程发出http请求的线程

任何关于如何杀死一个发出httppost请求并等待得到响应的线程的建议。我想从另一个并行运行的线程中终止这个线程，然后它才能收到来自请求的任何响应。我得到了关闭或中止http post请求的建议，但没有得到解决，有人能建议我们如何在这种情况下中止http请求或任何其他方式来实现这一点。

发出请求的线程在等待服务器响应时被阻止。如果获取线程转储并查看，它将位于某个read（）方法中，但不在thread.sleep中。因此，调用interrupt（）不会产生影响（除非它是interruptablechannel）。您有权访问发出post请求的套接字或输出流吗？如果是这样，您可以关闭它，它将带出一个异常的读取等待。你有一个代码样本可以放上去吗？

我想解决同样的问题。我编写了一个http请求runnable，它花了20秒超时并在一个线程（第一个线程）上执行。我在一个单独的线程（第二个线程）上编写了一个timeout runnable，它应该在10秒后中断/停止第一个线程。对于主线程中的每一秒（总共3个线程），我打印线程的状态，发现第一个线程一直在运行。

大家好，终于实现了这个关闭套接字的想法。下面是我试过的片段。
我的请求线程

package com.pkg.myhttptest;

import org.apache.http.client.methods.HttpPost;

public class RequestThread implements Runnable{

    Message msg = null;
    Util util = null;
    public RequestThread(Message msg, Util util) {
        this.msg = msg;
        this.util = util;
    }
    public void run() {
        System.out.println("its request thread");
        util.print(msg);
    }

}

取消线程

public class CancelThread implements Runnable {
    Message msg = null;
    Util util = null;
    public CancelThread(Message msg, Util util) {
        this.msg = msg;
        this.util = util;
    }
    public void run() {
        System.out.println("its cancel thread");
        int i=0;
        while(i<5){
            System.out.println("looping" + i);
            i++;
        }
        System.out.println(msg.getHttpost() + "In cancelled");
        Header[] hdr = msg.getHttpost().getAllHeaders();
        System.out.println(hdr.length + "length");
        msg.getHttpost().abort();

public class App 
{
    public static void main( String[] args )
    {
        Message msg = new Message();
        Util util = new Util();

        Thread reqThread = new Thread(new RequestThread(msg, util));
        Thread cancelThread = new Thread(new CancelThread(msg, util));

        System.out.println("Starting Threads");
        reqThread.start();
        try {
            reqThread.sleep(2000);
            cancelThread.start();
            cancelThread.join();
            System.out.println("closing..");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

我同意这是一个小小的不干净的代码，但它是有效的。它导致以下异常并终止线程。

java.net.SocketException: Socket is closed
    at java.net.Socket.getInputStream(Socket.java:876)
    at sun.security.ssl.SSLSocketImpl.doneConnect(SSLSocketImpl.java:644)
    at sun.security.ssl.SSLSocketImpl.<init>(SSLSocketImpl.java:549)

感谢所有努力帮助我的人。
