public static String getIp(HttpServletRequest request){
		 String ip = request.getHeader("X-Forwarded-For");  
         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip))  
            ip = request.getHeader("Proxy-Client-IP");  
         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip))  
            ip = request.getHeader("WL-Proxy-Client-IP");  
         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip))  
            ip = request.getHeader("HTTP_CLIENT_IP");  
         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip))  
            ip = request.getHeader("HTTP_X_FORWARDED_FOR");  
         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip))  
            ip = request.getRemoteAddr();  
         if ("127.0.0.1".equals(ip) || "0:0:0:0:0:0:0:1".equals(ip))  
            try {  
                ip = InetAddress.getLocalHost().getHostAddress();  
            }  
            catch (UnknownHostException unknownhostexception) {  
         }  
	     return ip;
	}

注意：此方法获取的是外网ip，及多个电脑与服务连的是同一个公网账号，则获取的ip是一样的
