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,它支持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通過擴展已有的Http Server API來實現,程序員必須自己實現HttpHandler接口,HttpServer會調用HttpHandler實現類的回調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實現類的回調方法.下面代碼演示了怎樣創建自己的Http Server

public class HTTPServerAPITester {
public static void main(String[] args) {
try {
HttpServer hs = HttpServer.create(new InetSocketAddress(8888),0);//設置HttpServer的端口為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 = "<h3>Happy New Year 2007!--Chinajash</h3>";
t.sendResponseHeaders(200, response.length());
OutputStream os = t.getResponseBody();
os.write(response.getBytes());
os.close();
}
}
