在Java中，我们可以使用内置的Socket和HttpURLConnection来创建一个简单的HTTP服务器。下面是一个基本的例子：

import java.io.*;
import java.net.*;
public class SimpleHttpServer {
    public static void main(String[] args) {
        try (ServerSocket server = new ServerSocket(8000)) {
            while (true) {
                Socket client = server.accept();
                try (PrintWriter writer = new PrintWriter(client.getOutputStream(), true);
                     BufferedReader reader = new BufferedReader(new InputStreamReader(client.getInputStream())))) {
                    // Handle incoming requests
                    String requestLine = reader.readLine();
                    if (requestLine != null && requestLine.startsWith("GET")) {
                        String pathInfo = requestLine.substring(requestLine.indexOf(' ') + 1)).trim();
                        if (pathInfo != null) {
                            writer.println("HTTP/1.1 200 OK");
                            writer.println("Content-Type: text/html");
                            writer.println();
                            // Generate HTML response
                            writer.println("<html><head><title>Simple HTTP Server</title></head>");
                            writer.println("<body><h1>Hello, World!</h1></body></html>");
                            client.close();
                        }
                    } else {
                        System.out.println("Unsupported request: " + requestLine));
                    }
                } catch (IOException e) {
                    System.out.println("Error handling request: " + e.getMessage());
                }
            }
        } catch (IOException | InterruptedException e) {
            System.out.println("Error starting server: " + e.getMessage());
        }
    }
}
