這篇文章主要介紹了java獲取服務(wù)器基本信息，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧
實(shí)現(xiàn)步驟：
（1）創(chuàng)建servlet BrowserServer
（2）調(diào)用HttpServletRequest對(duì)象的getServerName()方法獲取服務(wù)器名稱
（3）調(diào)用HttpServletRequest對(duì)象的getServerPort()方法獲取服務(wù)器端口
（4）首先調(diào)用getServletContext()方法獲取ServletContext對(duì)象，然后調(diào)用ServletContext對(duì)象的getServerInfo()方法獲取服務(wù)器環(huán)境信息名稱、版本信息
（5）利用HttpServletResponse對(duì)象的PrintWriter將信息顯示到頁(yè)面
