如果正在侦听连接，如何关闭套接字

import socket

# 创建套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定地址和端口
server_address = ('localhost', 8080)
server_socket.bind(server_address)

# 开始监听连接
server_socket.listen(5)

# 接受连接请求
client_socket, client_address = server_socket.accept()

# 关闭已建立的连接
client_socket.close()

# 停止接受新的连接请求
server_socket.close()

import java.net.ServerSocket;
import java.net.Socket;

public class Server {
    public static void main(String[] args) throws Exception {
        // 创建ServerSocket对象
        ServerSocket serverSocket = new ServerSocket(8080);

        // 开始监听连接
        Socket clientSocket = serverSocket.accept();

        // 关闭已建立的连接
        clientSocket.close();

        // 停止接受新的连接请求
        serverSocket.close();
    }
}
