Java网络编程中socket连接断开处理案例

在Java的网络编程中，Socket是实现客户端和服务器端通信的重要工具。然而，由于网络环境的不稳定，socket连接可能会断开。以下是一个简单的断开连接处理案例：

import java.io.*;
import java.net.*;
public class SocketConnectionHandler {
    private Socket socket;
    public SocketConnectionHandler(Socket socket) {
        this.socket = socket;
    }
    // Method to handle connection loss
    public void handleConnectionLoss() {
        try {
            // Check if the socket is still open
            if (socket != null && !socket.isClosed()) {
                System.out.println("Socket is still connected. Reconnecting...");
                // Try to reconnect with a new Socket object
                socket.close();
                socket = new Socket(socket.getRemoteSocketAddress()));
                // If successful, print a message and continue
                if (socket != null) {
                    System.out.println("Reconnected successfully. Resuming communication...");
                } else {
                    System.out.println("Failed to reconnect. Closing the connection.");
                }
            } else {
                System.out.println("Socket has already been closed or no longer connected.");
            }
        } catch (IOException e) {
            System.err.println("Error occurred while handling connection loss: " + e.getMessage());
            e.printStackTrace();
        }
        // Finally, close the socket
        try {
            if (socket != null && !socket.isClosed()) {
                socket.close();
            }
        } catch (IOException ex) {
            System.out.println("Error occurred while closing the socket: " + ex.getMessage());
        }
    }
}
