java - 我的 java 服务器在代码中间停止

Question

由于某种原因，我的服务器在代码的标记区域停止运行，但我不明白为什么。

import java.net.*;
import java.io.*;

public class SlickServer{
    public static void main(String[] args) throws IOException {

        int MAX_PLAYERS = 3;
        int playerNum = 0;
        Player[] players = new Player[MAX_PLAYERS];
        players[0] = new Player(25,25);
        players[1] = new Player(125,125);
        players[2] = new Player(225,225);
        ServerSocket serverSocket = new ServerSocket(40);
        boolean listening = true;

        while(listening){
            System.out.println("Waiting to connect with: " + playerNum);
            new ClientThread(serverSocket.accept(), players, playerNum).start();
            //stops here.
            System.out.println("Connected with: " + playerNum + " Now incrementing");
            playerNum++;
            System.out.println("Incremented to: " + playerNum);
        }



        serverSocket.close();
        System.exit(0);
    }
}

这是主题:

import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.*;
import java.io.*;

public class ClientThread extends Thread implements Runnable{
    Socket acceptedSocket;
    Player[] players;
    int playerNum;

    public ClientThread(Socket acceptedSocket, Player[] players, int playerNum){
        super("ClientThread");
        this.acceptedSocket = acceptedSocket;
        this.players = players;
        this.playerNum = playerNum;
    }

    public void run(){
        try{

            Socket clientSocket = acceptedSocket;
            System.out.println("Accepted. Now creating I/O.");
            ObjectInputStream in = new ObjectInputStream(clientSocket.getInputStream());
            ObjectOutputStream out = new ObjectOutputStream(clientSocket.getOutputStream());
            System.out.println("I/O with: " + playerNum + " working.");
            out.writeInt(playerNum);
            out.flush();
        }

        catch(Exception e){
            e.printStackTrace();
            System.exit(1);
        }


    }

    public void start(){
        run();
    }

}

“客户端线程”中的代码实际上在主线程上运行。

那是因为您编写了自己的 start 实现，但实际上并没有生成新线程。

你不想这样做。
