用Java实现一个简单的HTTP服务器

在Java中，我们可以使用内置的HttpServer类来创建一个简单的HTTP服务器。以下是一个基本的例子：

import java.io.IOException;
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 started on port " + PORT);
            while (true) {
                Socket clientSocket = serverSocket.accept();
                System.out.println("New connection accepted from " + clientSocket.getRemoteSocketAddress()));
                // Handle client requests here. For simplicity, we'll just echo the request back.
                String request = "GET / HTTP/1.1\r\nHost: localhost\r\n\r\n";
                try (Socket clientOutputSocket = clientSocket.getOutputStream();
                         PrintWriter writer = new PrintWriter(clientOutputSocket, true)))) {
                    writer.print(request);
                } catch (IOException e) {
                    System.out.println("Error handling client request: " + e.getMessage());
                }
            }
        } catch (IOException e) {
            System.err.println("Error starting HTTP server: " + e.getMessage());
            e.printStackTrace();
        }
    }
}
