如果是多级反向代理上面方法不不行的话会出现 x-forwarded-for获取的地址是一长串的多个ip地址
public static String getIpAddress(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(); //多级反向代理 if(ip.equals("127.0.0.1") || ip.equals("0:0:0:0:0:0:0:1")){ //根据网卡取本机配置的IP InetAddress inet=null; try { inet = InetAddress.getLocalHost(); } catch (UnknownHostException e) { e.printStackTrace(); } ip= inet.getHostAddress(); } } System.out.println(ip); return ip; }
