HttpServer类

import java.net.Socket;
import java.net.ServerSocket;
import java.net.InetAddress;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.IOException;

public class HttpServer {

// shutdown command
private static final String SHUTDOWN_COMMAND = "/SHUTDOWN";

        //the shutdown command received
        private boolean shutdown = false;
        public static void main(String[] args) {
                HttpServer server = new HttpServer();
                server.await();
        }
        public void await() {
        ServerSocket serverSocket = null;
        int port = 8080;
        try {
                serverSocket = new ServerSocket(port, 1, InetAddress.getByName("127.0.0.1"));
        } catch (IOException e) {
              e.printStackTrace();
              System.exit(1);

                OutputStream output = null;
                try {

                       input = socket.getInputStream();
                       output = socket.getOutputStream();
                       // create Request object and parse
                       Request request = new Request(input);
                       request.parse();

                       //create Response object
                       Response response = new Response(output);
                       response.setRequest(request);
                       response.sendStaticResource();

//Close the socket
socket.close();

                       //check if the previous URI is a shutdown command
                       shutdown = request.getUri().equals(SHUTDOWN_COMMAND);
                } catch (Exception e) {
                       e.printStackTrace();
                       continue;
                        }
                }
        }
}

代码中包含了一个webroot目录——>（用以测试程序的静态资源）

http://machineName:port/staticResource

请求静态资源，在浏览器地址或者URL框中输入如上地址

machineName 是指运行这个应用程序的计算机名称或者IP地址

port为8080

staticResource是被请求文件的文件名，它一定是在WEB_ROOT 中

http://localhost:8080/index.html

使用同一台计算机测试应用程序并且让HttpServer对象发送index.html文件

private static final String SHUTDOWN COMMAND = "/SHUTDOWN";

在host:port后输入预定义的字符串，Web浏览器发送shutdown命令。该命令由HttpServer类中的SHUTDOWN静态final变量定义

http://localhost:8080/SHUTDOWN

HttpServer类中的await方法
