클래스가 있습니다. Client, Server 및 Background가 Player 클래스에서 작동합니다. ObjectInputStream/ObjectOutputStream 인 클라이언트 클래스가 올바르게 작동하지 않는 이유를 정말로 이해하지 못합니다.ObjectInputStream/ObjectOutputStream 작업이 올바르지 않습니다.
내가 뭘 잘못하고있어? 내 실수는 어디 갔어?
package Shooter2Dv27082013;
public class Player implements Serializable{
....
public int x=10;
public int y=10;
.... }
package Shooter2Dv27082013;
public class Background extends JPanel implements ActionListener, Serializable {
public int countCollisions=0;
private int time = 20; // 0.02s
Timer mainTimer = new Timer(time, this);
....
Player p = new Player(); ... }
이제 클라이언트 클래스 :
package Shooter2Dv27082013;
import javax.swing.*;
import java.net.*;
import java.io.*;
public class Client {
public static void main(String[] ar) {
JFrame frame = new JFrame("D2 Shooter");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(1000, 520);
Background bg = new Background();
frame.add(bg);
frame.setResizable(false);
frame.setVisible(true);
int serverPort = 6666;
String address = "127.0.0.1";/
Player p = new Player();
try {
InetAddress ipAddress = InetAddress.getByName(address);
System.out.println("Any of you heard of a socket with IP address " + address + " and port " + serverPort + "?");
Socket socket = new Socket(ipAddress, serverPort);
System.out.println("Yes! I just got hold of the program.");
InputStream sin = socket.getInputStream();
OutputStream sout = socket.getOutputStream();
ObjectInputStream ois = new ObjectInputStream(sin);
ObjectOutputStream oos = new ObjectOutputStream(sout);
System.out.println("Streams are created. Let's try send these objects");
System.out.println();
System.out.println("P.x : "+bg.p.x);
while (true) {
oos.writeObject(bg.p);
oos.flush();
oos.close();
System.out.println("Player X: " + bg.p.x + " Player Y: " + bg.p.y);
p = (Player) ois.readObject();
ois.close();
System.out.println("New X: " + p.x + "New Y: "+p.y);
System.out.println("Looks like the server is pleased with us. Go ahead and enter more lines.");
System.out.println();
}
} catch (Exception x) {
x.printStackTrace();
}
}
}
이 서버 클래스에 객체를 전송하지 않습니다, 그러나 그것은 또한 오류에 대해 아무것도 말하지 않는다.
서버 클래스 :
package Shooter2Dv27082013;
import java.net.*;
import java.io.*;
public class Server {
public static void main(String[] ar) {
int port = 6666;
try {
ServerSocket ss = new ServerSocket(port);
System.out.println("Waiting for a client...");
Socket socket = ss.accept();
System.out.println("Got a client :) ... Finally, someone saw me through all the cover!");
System.out.println();
InputStream sin = socket.getInputStream();
OutputStream sout = socket.getOutputStream();
ObjectInputStream ois = new ObjectInputStream(sin);
ObjectOutputStream oos = new ObjectOutputStream(sout);
Player p = new Player();
while(true) {
p = (Player) ois.readObject();
System.out.println("The client just sent me this x: "+p.x+" y: "+p.y);
p.x=555; p.y=600;
System.out.println("I change it and now I'm sending it back...");
oos.writeObject(p);
oos.flush();
oos.close();
System.out.println("Waiting for the next line...");
System.out.println();
}
} catch(Exception x) { x.printStackTrace(); }
}
}
@ Eldar 코드에 문제가있는 것은 확실하지만이 문제 만 해결해도 문제가 해결되지는 않습니다. 게시 된 코드는 "스트림이 생성되었습니다.이 객체를 보내 봅시다"라는 문구를 인쇄하는 것까지까지 미치지 못합니다. – EJP
