Java网络编程：TCP连接断开处理实例

在Java网络编程中，当TCP连接断开时，我们通常需要进行一些错误处理和重连策略。以下是一个简单的例子：

import java.io.*;
import java.net.*;
public class TCPConnectionHandler {
    private Socket socket;
    private Thread thread;
    public void connect(String host, int port) {
        try {
            socket = new Socket(host, port);
            // 创建一个新的线程来处理客户端输入和输出
            thread = new Thread(new ClientInputHandler(socket)));
            thread.start();
            System.out.println("Connected to " + host + ":" + port);
        } catch (IOException e) {
            System.out.println("Error connecting to " + host + ":" + port);
            e.printStackTrace();
        }
    }
    // ...其他必要的方法和类
    private class ClientInputHandler implements Runnable {
        private Socket socket;
        public ClientInputHandler(Socket socket) {
            this.socket = socket;
        }
        @Override
        public void run() {
            try (DataInputStream in = new DataInputStream(socket.getInputStream()));) {
                String message;
                while ((message = in.readLine()) != null)) {
                    System.out.println("Received message: " + message);
                    // ...处理接收到的消息
                }
            } catch (IOException e) {
                System.out.println("Error reading from socket.");
                e.printStackTrace();
            }
        }
    }
}
