用Java实现简单web服务器

在java的官方文档中有一个实现的简单的web服务器,我把他稍加润色,试一下一个简单的web服务器,源码如下:

import com.sun.net.httpserver.*;
import java.net.*;
import java.io.*;

class MyHandler implements HttpHandler
{
    public void handle(HttpExchange t) throws IOException
    {
        //InputStream is = t.getRequestBody();

        //read(is);

        String response = "This is the response";
        t.sendResponseHeaders(200,response.length());
        OutputStream os = t.getResponseBody();
        os.write(response.getBytes());
        os.close();
    }
}

public class MyServer
{
    public static void main(String argv[]) //throws IOException

    {
        try
        {
            HttpServer server = HttpServer.create(new InetSocketAddress(8000),0);
            server.createContext("/myapp",new MyHandler());
            server.setExecutor(null);
            server.start();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
}


你可以用做测试,当然页面内容很简单,只是显示一行"This is response"的字符串,下一步,将继续加强这个服务器的功能.这个贴子的例子还是蛮有帮助作用的.
