我有类：客户端、服务器和背景正在使用 Player 类。我真的不明白为什么我的ObjectInputStream/客户端类ObjectOutputStream不能正常工作。
我在做什么坏事？我的错在哪里？
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(); ... }
现在客户端类：
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();
}
}
}
它不会将 Object 发送到 Server 类，但它也没有说明错误。
服务器类：
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(); }
}
}
