Java 尝试重新打开连接时发生套接字关闭错误

我正在制作一个程序，每次客户端从服务器接收数据时都需要更新UI。为此，每次都必须关闭并重新打开套接字和服务器套接字。尽管当程序尝试接受新连接时，以下是我的代码和错误：

    public void startServer(){
    Thread serverstart = new Thread(){
        public void run() {
                try {       
                    serversocket = new ServerSocket(socket);

                    while(true){
                        skt = serversocket.accept();
                        close.setEnabled(true);
                        new Thread(new newClient(skt)).start();
                    }
            } catch (IOException e){
                e.printStackTrace();
              }
        }
    };serverstart.start();
}
static class newClient implements Runnable {
    private Socket socket;
    static PrintStream output;
    public newClient(Socket skt){
        this.socket = skt;
    }
    @Override
    public void run(){
        try {
        output = new PrintStream(socket.getOutputStream());
        } catch(IOException ioe){
            ioe.printStackTrace();
        }
    }
}

    public void sendData(){                 
        tallydata = Integer.toString(preview) + " " + Integer.toString(program);        
                System.out.println(tallydata);
                newClient.output.print(tallydata);

        try{
                skt.close();
                serversocket.close();
            } catch(IOException e){
                e.printStackTrace();
            } 
            startServer();                  
    }

    at TallySystem.servergui$1.run(servergui.java:201)

套接字在sendData（）方法的末尾关闭，然后调用startServer（）方法重新启动连接。以下是错误：

    public void startServer(){
    Thread serverstart = new Thread(){
        public void run() {
                try {       
                    serversocket = new ServerSocket(socket);

                    while(true){
                        skt = serversocket.accept();
                        close.setEnabled(true);
                        new Thread(new newClient(skt)).start();
                    }
            } catch (IOException e){
                e.printStackTrace();
              }
        }
    };serverstart.start();
}
static class newClient implements Runnable {
    private Socket socket;
    static PrintStream output;
    public newClient(Socket skt){
        this.socket = skt;
    }
    @Override
    public void run(){
        try {
        output = new PrintStream(socket.getOutputStream());
        } catch(IOException ioe){
            ioe.printStackTrace();
        }
    }
}

    public void sendData(){                 
        tallydata = Integer.toString(preview) + " " + Integer.toString(program);        
                System.out.println(tallydata);
                newClient.output.print(tallydata);

        try{
                skt.close();
                serversocket.close();
            } catch(IOException e){
                e.printStackTrace();
            } 
            startServer();                  
    }

谢谢。

为什么要关闭并重新打开服务器？只要启动一次，别管它。这就是它应该被使用的方式

无论如何，根据：

公众假期结束（）

关闭此套接字。当前在accept（）中阻塞的任何线程都将抛出SocketException

这正是你的问题。您正在关闭ServerSocket，而它正忙于等待连接
