serversocket和serversocketchannel实现http服务

ServerSocket:

package com.http;

import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class MyServer {

    public static void main(String[] args) throws java.io.IOException,java.lang.InterruptedException {

        ServerSocket ss = new ServerSocket(8000);
        
        Socket socket = null;
        
        while((socket = ss.accept())!= null){
            PrintWriter out = new PrintWriter(socket.getOutputStream());
            
            out.println("HTTP/1.1 200");
            out.println("Content-Type: text/html");
            out.println("Date: Thu, 26 Jul 2018 01:54:53 GMT");
            
            out.println();
            
            out.println("<html><head><title>Hello</title></head><body><h1>hello world aaaa</h1>");
            
            out.flush();
            
            
            out.println("</body></html>");
            
            out.flush();
            
            socket.shutdownOutput();
        }
    }

}

ServerSocketChannel:

package com.http;

import java.net.InetSocketAddress;
import java.nio.ByteBuffer;
import java.nio.channels.SelectionKey;
import java.nio.channels.Selector;
import java.nio.channels.ServerSocketChannel;
import java.nio.channels.SocketChannel;
import java.util.Iterator;

public class MyNioServer {

    public static void main(String[] args) throws Exception {

        ServerSocketChannel ssc = ServerSocketChannel.open();
        
        ssc.configureBlocking(false);
        
        Selector selector = Selector.open();
        
        ssc.register(selector, SelectionKey.OP_ACCEPT);
        
        ssc.bind(new InetSocketAddress(8000));
        
        while(true){
            selector.select();
            
            Iterator<SelectionKey> it = selector.selectedKeys().iterator();
            
            while(it.hasNext()){
                SelectionKey key = it.next();
                
                if (key.isValid() && key.isAcceptable()){
                    
                    SocketChannel sc = ssc.accept();
                    
                    sc.configureBlocking(false);
                    
                    ByteBuffer buf = ByteBuffer.allocate(1024);
                    
                    buf.put("HTTP/1.1 200
".getBytes());
                    buf.put("Content-Type: text/html
".getBytes());
                    buf.put("Date: Thu, 26 Jul 2018 01:54:53 GMT
".getBytes());
                    buf.put("
".getBytes());
                    buf.put("<html><head><title>Hello</title></head><body><h1>hello world aaaa</h1></body></html>".getBytes());
                    
                    buf.flip();
                    
                    sc.write(buf);
                    
                    
                    sc.shutdownOutput();
                    
                    //sc.close();
                    
                }
            }
        }
    
    }

}
