获取客户端真实的IP地址

public String getRealIp(HttpServletRequest request) {
        String ip = request.getHeader("X-Forwarded-For");
        if (StringUtils.isNotEmpty(ip) && !"unKnown".equalsIgnoreCase(ip)) {
            int index = ip.indexOf(",");
            if (index != -1) {
                return ip.substring(0, index);
            } else {
                return ip;
            }
        }
        ip = request.getHeader("X-Real-IP");
        if (StringUtils.isNotEmpty(ip) && !"unKnown".equalsIgnoreCase(ip)) {
            return ip;
        }
        return request.getRemoteAddr();
    }

获取客户端使用设备类型

public String getClientInfo(HttpServletRequest request) {
        String userAgent = request.getHeader("user-agent");
        String device = null;
        //移动端访问
        if (userAgent.contains("Android") || userAgent.contains("iPhone") || userAgent.contains("iPad")){
            device = "mobileTerminal";
            request.setAttribute("device", device);
        }else {
            //PC端访问
            device = "pcTerminal";
        }
        return device;
    }
