Java网络编程：TCP连接断开问题实例

在Java的网络编程中，TCP（Transmission Control Protocol）连接的断开是一个常见的问题。这里我们将通过一个实例来理解和解决这个问题。

首先，我们需要创建一个Socket服务器端：

import java.io.IOException;
import java.net.ServerSocket;
public class Server {
    private static final int PORT = 1234; // 配置监听端口
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = new ServerSocket(PORT);
        System.out.println("Server is listening on port " + PORT);
        // 监听客户端连接，并为每个连接创建一个Socket
        while (true) {
            Socket clientSocket = serverSocket.accept();
            System.out.println("New connection from " + clientSocket.getRemoteSocketAddress()));
            // 创建一个新的线程来处理这个连接，通常这里的操作会涉及到网络通信
            new Thread(() -> handleClient(clientSocket)).start();
        }
    }
    private static void handleClient(Socket socket) {
        try (Socket client = socket.accept(); DataOutputStream out = new DataOutputStream(client.getOutputStream()); DataInputStream in = new DataInputStream(socket.getInputStream())) {
            // 这里可以进行你的网络通信操作，比如发送数据、接收数据等
            System.out.println("Handling the client request...");
            // 发送响应数据
            out.writeUTF("ACK: Your request has been processed successfully!");
            // 读取并打印客户端的请求数据
            String requestData = in.readUTF();
            System.out.println("Received request data: " + requestData);
            // 向客户端发送响应数据
            in.writeUTF("Response to your request: " + requestData + ", Processed successfully!");
        } catch (IOException e) {
            System.err.println("Error occurred while handling client request: " + e.getMessage());
            e.printStackTrace();
        }
    }
}
