基于tcp协议的简易聊天机器人要求能通过关键字回答问题用Java实现代码

好的，以下是基于TCP协议的简易聊天机器人的Java实现代码示例：

服务端：

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.HashMap;
import java.util.Map;

public class Server {
    private static final int PORT = 8888;

    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(PORT);
            System.out.println("服务端已启动，等待客户端连接...");
            Socket socket = serverSocket.accept();
            System.out.println("客户端已连接，IP地址为：" + socket.getInetAddress().getHostAddress());

            // 模拟关键字回答
            Map<String, String> keywordMap = new HashMap<>();
            keywordMap.put("你好", "您好，请问有什么可以帮助您的？");
            keywordMap.put("再见", "欢迎下次再来！");
            keywordMap.put("天气", "今天天气晴朗，气温适宜。");

            BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));

            while (true) {
                String msg = reader.readLine();
                if (msg != null) {
                    System.out.println("客户端：" + msg);
                    String replyMsg = "不好意思，我没听懂您说的话。";
                    for (String keyword : keywordMap.keySet()) {
                        if (msg.contains(keyword)) {
                            replyMsg = keywordMap.get(keyword);
                            break;
                        }
                    }
                    writer.write(replyMsg);
                    writer.newLine();
                    writer.flush();
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

客户端：

import java.io.*;
import java.net.Socket;
import java.util.Scanner;

public class Client {
    private static final String IP_ADDRESS = "127.0.0.1";
    private static final int PORT = 8888;

    public static void main(String[] args) {
        try {
            Socket socket = new Socket(IP_ADDRESS, PORT);
            System.out.println("已连接服务端，可以开始聊天了！");

            BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));

            Scanner scanner = new Scanner(System.in);
            while (true) {
                String msg = scanner.nextLine();
                writer.write(msg);
                writer.newLine();
                writer.flush();
                String replyMsg = reader.readLine();
                System.out.println("服务端：" + replyMsg);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

以上代码示例中，我们通过socket建立连接，并在服务端模拟关键字回答，客户端输入问题后，通过socket将问题发送到服务端，服务端根据关键字匹配返回相应的答案，客户端再将服务端的回复输出到控制台。
