创建一个java服务器套接字，该套接字使用线程池等待来自客户端的消息

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

int port = 8080; // 服务器监听的端口号
ServerSocket serverSocket = new ServerSocket(port);

int threadPoolSize = 10; // 线程池大小
ExecutorService executorService = Executors.newFixedThreadPool(threadPoolSize);

while (true) {
    Socket clientSocket = serverSocket.accept(); // 等待客户端连接
    executorService.execute(new ClientHandler(clientSocket)); // 将客户端连接交给线程池处理
}

class ClientHandler implements Runnable {
    private Socket clientSocket;

    public ClientHandler(Socket clientSocket) {
        this.clientSocket = clientSocket;
    }

    @Override
    public void run() {
        // 在这里处理客户端的消息
        // 可以使用clientSocket.getInputStream()读取客户端发送的消息
        // 可以使用clientSocket.getOutputStream()向客户端发送消息
    }
}
