如何用Java实现一个简单的HTTP服务器？

在Java中，我们可以使用Java的内置类如ServerSocket和Socket来实现一个简单的HTTP服务器。以下是一个基本的例子：

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
public class SimpleHttpServer {
    private static final int PORT = 8000; // Change this to any available port
    public static void main(String[] args) {
        try (ServerSocket serverSocket = new ServerSocket(PORT)) {
            System.out.println("HTTP server is running on port " + PORT);
            while (true) {
                Socket clientSocket = serverSocket.accept();
                System.out.println("New connection from " + clientSocket.getRemoteSocketAddress()));
                // Handle the client request here
                // For a simple HTTP server, you can send a response back to the client
                String response = "Hello, World! You accessed this HTTP server on port " + PORT;
                OutputStream outputStream = clientSocket.getOutputStream();
                outputStream.write(response.getBytes());
                outputStream.flush();
                clientSocket.close();
            }
        } catch (IOException e) {
            System.err.println("Error occurred: " + e.getMessage());
            e.printStackTrace();
        }
    }
}
