Я пытаюсь создать чат в java, используя Socket и ServerSocket, и клиент и сервер успешно подключаются друг к другу через IP-адреса. Но как только я подключаюсь и пытаюсь ввести что-то в textField, весь чат зависает, и мне приходится выходить из приложения, чтобы остановить его. Знаете ли вы какие-либо причины, по которым это может происходить?
Это сервер
public class Server {
public static void main(String[] args) throws IOException {
System.out.println("The server is running");
int clientNumber = 1;
ServerSocket listener = new ServerSocket(9092);
try{
while(true){
new Chat(listener.accept(), clientNumber++).start();
}
}finally{
listener.close();
}
}
private static class Chat extends Thread{
private Socket socket;
private int clientNumber;
public Chat(Socket socket, int clientNumber) {
this.socket = socket;
this.clientNumber = clientNumber;
System.out.println("You have connected as " + clientNumber +".");
}
public void run(){
try{
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
out.println("You can chat with any other people who have connected");
out.println("To leave just enter a single slash");
out.println(clientNumber + " people have connected.");
while(true){
String input = in.readLine();
if(input == null || input.equals("/")){
break;
}
out.println("Client #" + clientNumber +":" + input);
}
}catch (IOException e) {
System.out.println("Error handling client# " + clientNumber + ": " + e);
} finally {
try {
socket.close();
} catch (IOException e) {
System.out.println("Couldn't close socket");
}
System.out.println("Client #" + clientNumber + " has ended the connection");
}
}
}
}
Это клиент
public class Client implements KeyListener {
private BufferedReader in;
private PrintWriter out;
private JFrame frame = new JFrame("Chat Room");
private JTextField dataField = new JTextField(100);
private JTextArea messageArea = new JTextArea(10, 100);
public Client(){
messageArea.setEditable(false);
frame.getContentPane().add(dataField, "South");
frame.getContentPane().add(messageArea, "Center");
dataField.addKeyListener(this);
}
public void connectToServer() throws Exception{
String serverAddress = JOptionPane.showInputDialog(frame,
"Enter IP Address of the Server:",
"Welcome to the Capitalization Program",
JOptionPane.QUESTION_MESSAGE);
Socket socket = new Socket(serverAddress, 9092);
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
out = new PrintWriter(socket.getOutputStream());
for(int i =0; i<3; i++){
messageArea.append(in.readLine() +"\n");
}
}
public static void main(String[] args) throws Exception {
Client client = new Client();
client.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
client.frame.pack();
client.frame.setVisible(true);
client.connectToServer();
}
@Override
public void keyTyped(KeyEvent e) {
// TODO Auto-generated method stub
}
@Override
public void keyPressed(KeyEvent e) {
int c = e.getKeyCode();
if(c == KeyEvent.VK_ENTER) {
out.println(dataField.getText());
String response;
try{
response = in.readLine();
if(response == null || response.equals("")){
System.exit(0);
}
} catch (IOException ex){
response = "Error: " + ex;
}
messageArea.append(response + "\n");
dataField.setText("");
}
}
@Override
public void keyReleased(KeyEvent e) {
// TODO Auto-generated method stub
}
}
