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,在這里,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

????????????hs.createContext("/soddabao",?new?MyHandler());//用MyHandler類內處理到/chinajash的請求
