帮我用java写一个简易的基于C/S的图书管理系统

好的，下面是一个简单的基于C/S的图书管理系统的Java代码：

服务端(Server.java)：

import java.io.*;
import java.net.*;

public class Server {
    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(8888);
            System.out.println("服务器已启动，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());

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

            while (true) {
                String request = reader.readLine();
                System.out.println("接收到客户端请求：" + request);

                if ("exit".equals(request)) {
                    System.out.println("客户端已断开连接");
                    break;
                }

                String response = handleRequest(request);
                writer.write(response + "\n");
                writer.flush();
                System.out.println("发送响应给客户端：" + response);
            }

            reader.close();
            writer.close();
            socket.close();
            serverSocket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static String handleRequest(String request) {
        // 处理请求的逻辑
        return "请求已处理";
    }
}

客户端(Client.java)：

import java.io.*;
import java.net.*;

public class Client {
    public static void main(String[] args) {
        try {
            Socket socket = new Socket("127.0.0.1", 8888);
            System.out.println("已连接到服务器");

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

            BufferedReader consoleReader = new BufferedReader(new InputStreamReader(System.in));

            while (true) {
                System.out.print("请输入命令：");
                String command = consoleReader.readLine();
                writer.write(command + "\n");
                writer.flush();

                String response = reader.readLine();
                System.out.println("服务器响应：" + response);

                if ("exit".equals(command)) {
                    break;
                }
            }

            reader.close();
            writer.close();
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

以上代码只是一个简单的示例，实现的功能也很简单，只是简单地通过控制台输入命令，并将命令发送给服务端，服务端收到命令后做出相应的处理，并将处理结果返回给客户端。在实际开发中，需要根据需求来设计更加完善的功能。
