*、jsp页面上通过request获取域名
String contextPath = request.getContextPath(); StringBuffer url= request.getRequestURL(); String head=headerReferer.substring(0,url.indexOf(contextPath)+contextPath.length()+1); request.setAttribute("httpheadd",httpheadd); httpheadd = 域名+程序的根名称+‘/’
备注:通过上面一行可通过${httpheadd}使用获取的域名信息
应用实例:http://www.cae.cn/cae/jsp/player/p_player.jsp?url=网络的绝对地址即可(在线播放)
