JDK6提供了一個(gè)簡(jiǎn)單的Http Server API,據(jù)此我們可以構(gòu)建自己的嵌入式Http Server,它支持Http和Https協(xié)議,提供了HTTP1.1的部分實(shí)現(xiàn)，沒(méi)有被實(shí)現(xiàn)的那部分可以通過(guò)擴(kuò)展已有的Http Server API來(lái)實(shí)現(xiàn),程序員必須自己實(shí)現(xiàn)HttpHandler接口,HttpServer會(huì)調(diào)用HttpHandler實(shí)現(xiàn)類的回調(diào)方法來(lái)處理客戶端請(qǐng)求,在這里,我們把一個(gè)Http請(qǐng)求和它的響應(yīng)稱為一個(gè)交換,包裝成HttpExchange類,HttpServer負(fù)責(zé)將HttpExchange傳給HttpHandler實(shí)現(xiàn)類的回調(diào)方法.下面代碼演示了怎樣創(chuàng)建自己的Http Server
