如何在不阻塞 ServerSocket 的情况下获取待处理请求的数量或接受请求？

Question

我创建了 java.net.ServerSocket 的子类。

在 run 方法中，我想获取所有待处理的请求并向它们发送错误消息。

如何使用 ServerSocket？

这是我的代码：

public class SafeWalkServer extends ServerSocket implements Runnable {

    public SafeWalkServer(int port) throws IOException {
        super(port);

    }

    @Override
    public void run() {
        try {
            boolean isShutdown = false;
            while (!isShutdown) {
                Socket client = accept();
                BufferedReader reader = new BufferedReader(new InputStreamReader(client.getInputStream()));
                PrintWriter writer = new PrintWriter(client.getOutputStream());

                if (clientText.startsWith(":RESET"))
**//at this point I need to send error message to all pending requests.**
                        Socket sock = accept(); 
}
}
}
}

我需要待处理请求的数量或 accept 的非阻塞变体？

Answer 1

你可以用 ServerSocketChannel. call configureBlocking(false) to do non-blocking. There are many good tutorials (with sample code) like The Rox Java NIO Tutorial.

做非阻塞套接字
