代码如下（网上参考而来）：

import java.io.IOException;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Date;
public class HttpServlet implements Runnable {
    ServerSocket server;
    public HttpServlet() throws UnknownHostException, IOException {
        server = new ServerSocket(8888);
    }
    public static void main(String[] args) throws Exception {
        Thread t = new Thread(new HttpServlet());
        t.start();
    }
    public void run() {
        boolean listening = true;
        while (listening) {
            try {
                Socket client = server.accept();
                System.out.println("client:" + client);
                PrintStream out = new PrintStream(client.getOutputStream(), true);
                String content = "<h1>It works.<h1>/r/n";
                out.print("HTTP/1.0 202 OK" + "/r/n");
                out.print("Server: testserver" + "/r/n");
                out.print("Date: " + new Date() + "/r/n");
                out.print("Content-length: " + content.length() + "/r/n");
                out.print("Content-type: text/html" + "/r/n");
                out.print("/r/n");
                out.print(content);
                out.flush();
                out.close();
                client.close();
            } catch (Exception ex) {
                System.out.println(ex.getMessage());
            }
        }
        if (server != null) {
            try {
                server.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
