socket返回数据失败

Question

import java.io.*;
import java.net.InetAddress;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.UnknownHostException;

public class HttpServer {
    public static final String WEB_ROOT = System.getProperty("user.dir") + File.separator + "src\\main\\java\\ex01\\static";

    public static void main(String[] args) throws IOException, InterruptedException {
        HttpServer server = new HttpServer();
        server.await();
    }

    public void await(){
        ServerSocket serverSocket = null;
        int port = 8999;
        try{
            serverSocket = new ServerSocket(port,1, InetAddress.getByName("127.0.0.1"));
        } catch (IOException e) {
            e.printStackTrace();
            System.exit(1);
        }
        Socket socket = null;
        try {
            socket = serverSocket.accept();
        } catch (IOException e) {
            e.printStackTrace();
        }
        PrintWriter printWriter = null;
        try {
            printWriter = new PrintWriter(socket.getOutputStream());
        } catch (IOException e) {
            e.printStackTrace();
        }
        String errorMessage = "HTTP/1.1 404 File Not Found\r\n"+
                "Content-Type: text/html\r\n" +
                "Content-Length: 23\r\n" +"\n"+
                "<h1>File Not Found</h1>";
        printWriter.println(errorMessage);
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

我在浏览器访问http://127.0.0.1:8999/home 却无法访问。

输出为：

Connected to the target VM, address: '127.0.0.1:49586', transport: 'socket'
