Java : clean up runnable object with socket

Question

我正在用 Java 编写一个多线程服务器应用程序。
一切正常，但有一个小问题。
当我停止监听传入连接请求的 runnable 时，套接字保持存在。所以我的问题是:如何停止可运行对象并清除在该可运行对象中创建的所有对象？

停止线程的代码:

Runnable tr = new Worldwide() ; 
        Thread thread = new Thread(tr) ;
        thread.start() ; 
        online =  true ;

        while (core.getServerSate()) {
            try{
            Thread.sleep(200);
            } catch (Exception e ) {
                e.printStackTrace();
            }
        } ;
        thread.stop() ;
        thread.
        core.printToConsole("Server is offline now") ; 

可运行代码:

public class Worldwide implements Runnable  { 

Core core = Core.getInstance()  ; 

public Worldwide () {

}
@Override
public void  run() { 

    try {
    ServerSocket server = new ServerSocket(port) ;

    core.printToConsole("Server is online") ; 
    core.printToConsole ( "listening on port :" +  server.getLocalPort()) ; 
    while (core.getServerSate() == true) {

        Socket client = server.accept() ; 
        Runnable tr = new ClientCommunication(client) ; 
        new Thread (tr).start() ;

    }

    }
    catch(Exception e ) {
        core.printToConsole ("An error occured while going online") ; 
        e.printStackTrace() ; 
    } 
    }

谢谢，汤姆

您可以从主线程关闭套接字。这将中断对 accept 的调用并导致它抛出 IOException .然后您可以退出接受线程的 run方法来自 IOException .
