我正在使用此代码使用libgdx net api启动一个简单的服务器(我目前正在使用libgdx,所以我将来会使用这个api)

  Server server = new Server(1234);

该行调用此类:

package com.me.mygdxgame;

import java.io.BufferedReader;
import java.io.InputStreamReader;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Net;
import com.badlogic.gdx.net.ServerSocket;
import com.badlogic.gdx.net.Socket;

public class Server extends Thread {
    int port;
    ServerSocket server;
    boolean running = true;

    public Server(int port) {
    this.port = port;

    this.start();
    }

    @Override
    public void run() {
    Socket s = null;
    String text = "";
    try {
        server = Gdx.net.newServerSocket(Net.Protocol.TCP, port, null);
        s = server.accept(null);
        BufferedReader in = new BufferedReader(new InputStreamReader(
            s.getInputStream()));
        while (s.isConnected()) {
        text = in.readLine();
        if (text != "") {
            Gdx.app.log("Output", text);
            Gdx.app.exit();
        }
        }

        in.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
    }
}

我的问题是,我一直在收到JVM BIND错误。我正在使用端口1234.它在我的路由器配置中打开(我打开它),未使用的netstat说。该程序在我的防火墙中是whitelistet,所以我不知道问题出在哪里。这是错误(它重​​复无限次,直到我关闭程序(虽然没有任何循环?)

端口1234已在使用中。检查netstat。也许您的程序的早期实例仍在运行,或者仍有端口处于TIME-WAIT状态。
