JDK6.0的新特性之五：輕量級Http Server

JDK6提供了一個簡單的Http Server API,據此我們可以構建自己的嵌入式Http Server,它支援Http和Https協議,提供了HTTP1.1的部分實現，沒有被實現的那部分可以透過擴充套件已有的Http Server API來實現,程式設計師必須自己實現HttpHandler介面,HttpServer會呼叫HttpHandler實現類的回撥方法來處理客戶端請求,在這裡,我們把一個Http請求和它的響應稱為一個交換,包裝成HttpExchange類,HttpServer負責將HttpExchange傳給HttpHandler實現類的回撥方法.下面程式碼演示了怎樣建立自己的Http Server

/**

public class HTTPServerAPITester {
public static void main(String[] args) {
try {
HttpServer hs = HttpServer.create(new InetSocketAddress(8888),0);//設定HttpServer的埠為8888
hs.createContext("/chinajash", new MyHandler());//用MyHandler類內處理到/chinajash的請求 hs.setExecutor(null); // creates a default executor
hs.start();
} catch (IOException e) {
e.printStackTrace();
}
}
}

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

Happy New Year 2007!--Chinajash

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