Question

我正在尝试使用GUI组件实现聊天服务器。我实现了3个部分（服务器，客户端和GUI组件）。

以下是我遇到的一些问题 -

我无法使用GUI代码包装代码。
与客户交谈时，只有当每个人只输入一行并按回车键时，它才有效。

代码：

第一个GUI组件：

public class ChatServer extends javax.swing.JFrame {
    String str;

    public ChatServer() {
        initComponents();      
        screen.setEditable(false);
    }

private void sendActionPerformed(java.awt.event.ActionEvent evt) {                                     
    str = enter.getText();
    enter.setText("");
    screen.append(str+"\n");

}

public static void main(String args[]) {
        new ChatServer().setVisible(true);
}

    private javax.swing.JTextPane enter;
    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JScrollPane jScrollPane2;
    private javax.swing.JTextArea screen;
    private javax.swing.JButton send;

}

看起来像：

enter image description here

这是我的服务器代码：

public class Server {
    /**
     * @param args
     * @throws IOException 
     */
    public static void main(String[] args) throws IOException {
        ServerSocket ss = new ServerSocket(23);
        System.out.println(InetAddress.getLocalHost()+" hazir");
        while(true){
            Socket s = ss.accept();
            System.out.println(s.getInetAddress().getHostName() + " baglandi");
            new ServerPart(s).start();
        }
    }

}

public class ServerPart extends Thread {
    private Socket s;
    public ServerPart(Socket s){
        this.s=s;
    }

    @Override
    public void run() {

        try {

            PrintStream ps = new PrintStream(s.getOutputStream());

            ps.println("Hello" + s.getInetAddress().getHostName());

            String gelen;

            while(true){ 

            Scanner sc = new Scanner(s.getInputStream());   

            gelen = sc.nextLine();

            if(gelen.trim().equalsIgnoreCase("bye"))
                break;


            System.out.println("Client: " + gelen);

            BufferedReader input = new BufferedReader( 
                    new InputStreamReader(System.in) );

            ps.println("Server: " + input.readLine());

            }

            s.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }
}

客户代码：

public class Client extends Thread {
    private Socket s;
    public Client(Socket s){
        this.s=s;
    }

    @Override
    public void run() {
        try {

            PrintStream ps = new PrintStream(s.getOutputStream());

            Scanner sc = new Scanner(s.getInputStream());

            ps.println("Hello" + s.getInetAddress().getHostName());

            String gelen;

            while(true){

                BufferedReader input = new BufferedReader( 
                        new InputStreamReader(System.in) );

            gelen = sc.nextLine();

            if(gelen.trim().equalsIgnoreCase("bye"))
                break;

            System.out.println("Client: " + gelen);
            ps.println("Server: " + input.readLine());


            }

            s.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }

    /**
     * @param args
     * @throws IOException 
     * @throws UnknownHostException 
     */
    public static void main(String[] args) throws UnknownHostException, IOException {

        Socket s = new Socket("192.168.1.173", 23);

        new Client(s);

    }

}

如果你能帮我配偶，我将不胜感激。

您正在使用PrintStream类，方法ps.readline();。如果您正在开发一个聊天应用程序，那么这种方法将不起作用，因为readline方法在找到换行符或文件结束时，或者当回车符即输入时终止流。所以我更喜欢使用.. datainputstream和dataoutputstream -

Socket sc = new Socket("address",port);
DataOutputStream daos;
DataInputStream dis;
dis = new DataInputStream(sc.getInputStream());
daos= new DataOutputStream(sc.getOutputStream());

带有GUI的java ChatServer
