java聊天程序服务器端无法显示内容，代码在内容中

[qwevert34543345]

要实现的功能就是：同时打开多个客户端，并在输入窗口中发送的消息，在服务器上打印。（问题：在服务器上无法打印出客户端内容)

客户端：
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.io.*;
public class ChatClient extends Frame {
TextArea ta = new TextArea();
TextField tf = new TextField();
Socket s = null;
DataOutputStream dos = null;

public static void main(String[] args) {
new ChatClient().launchFrame();
}
//创建输入界面，并添加监听器
public void launchFrame() {
setLocation(400,400);
this.setSize(300,500);
add(ta,BorderLayout.CENTER);
add(tf,BorderLayout.SOUTH);
addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
disconnected();
System.exit(0);
}
});
tf.addActionListener(new TfListener());
setVisible(true);
connected();
}
//连接服务器端口
public void connected(){
try {
s = new Socket("127.0.0.1",8869);
dos = new DataOutputStream(s.getOutputStream());
System.out.println("connected");

} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
//断开服务器端口
public void disconnected(){
try {
dos.close();
s.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
//行为事件
private class TfListener implements ActionListener{
public void actionPerformed(ActionEvent e){
String str = tf.getText().trim();
ta.setText(str);
tf.setText("");
try{
dos.writeUTF(str);
dos.flush();
}catch(IOException e1){
e1.printStackTrace();
}
}
}
}


服务器：
import java.io.*;
import java.net.*;

public class ChatServer {

boolean started = false;
ServerSocket ss = null;

public static void main(String[] args) {
new ChatServer().start();
}
//服务器端口启动
public void start() {
try {
ss = new ServerSocket(8869);
started = true;
} catch (BindException e) {
System.out.print("端口使用中");
//System.exit(0);
} catch (IOException e) {
e.printStackTrace();
}
try {
while (started) {
Socket s = ss.accept();
Client c = new Client(s);
new Thread(c).start();
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
ss.close();
} catch (IOException e) {
e.printStackTrace();
}
}

}
//多线程同时接受多个客户端
class Client implements Runnable {
private Socket s;
String str = null;
private DataInputStream dis = null;

// private String str = null;

private boolean bConnected = false;

public Client(Socket s) {
this.s = s;

try {
dis = new DataInputStream(s.getInputStream());
bConnected = true;

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

}

public void run() {
try {
while (bConnected)
str = dis.readUTF();
System.out.println(str);
} catch (EOFException e) {
System.out.print("windows closed");
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (dis != null)
dis.close();
if (s != null)
s.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

}
}

看着代码头就晕...抢个沙发

明天回复你

楼主你的问题我找到了。服务器端run方法里的代码：
while (bConnected)
str = dis.readUTF();
System.out.println(str);
变成下面这样就可以了：
while (bConnected) {
str = dis.readUTF();
System.out.println(str);
}
由于你没加大括号，一直不停的读，但没往控制台上打印。
