JDK6提供了一个简单的Http Server API,据此我们可以构建自己的嵌入式Http Server,它支持Http和Https协议,提供了HTTP1.1的部分实现，没有被实现的那部分可以通过扩展已有的Http Server API来实现,程序员必须自己实现HttpHandler接口,HttpServer会调用HttpHandler实现类的回调方法来处理客户端请求,在这里,我们把一个Http请求和它的响应称为一个交换,包装成HttpExchange类,HttpServer负责将HttpExchange传给HttpHandler实现类的回调方法.下面代码演示了怎样创建自己的Http Server
package jdk6;
import java.io.IOException;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpServer;
public class HTTPServerAPITester 
{
/** *//**
* The main method.
*
* @param args the args
*/
public static void main(String[] args) {
try {
HttpServer hs = HttpServer.create(new InetSocketAddress(8888),0);//设置HttpServer的端口为8888
hs.createContext("/soddabao", new MyHandler());//用MyHandler类内处理到/chinajash的请求
hs.setExecutor(null); // creates a default executor
hs.start();
} catch (IOException e) {
e.printStackTrace();
}
}
}package jdk6;
import java.io.IOException;
import java.io.OutputStream;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
// TODO: Auto-generated Javadoc
/** *//**
* The Class MyHandler.
*/
public class MyHandler implements HttpHandler {
/**//* (non-Javadoc)
* @see com.sun.net.httpserver.HttpHandler#handle(com.sun.net.httpserver.HttpExchange)
*/
public void handle(HttpExchange httpexchnge) throws IOException {
httpexchnge.getRequestBody();
String response = "<h3>Happy New Year 2007!--Soddabao</h3>";
httpexchnge.sendResponseHeaders(200, response.length());
OutputStream os = httpexchnge.getResponseBody();
os.write(response.getBytes());
os.close();
}
}
