private String getIpAddr(HttpServletRequest request) {String ipAddress = null;// ipAddress = this.getRequest().getRemoteAddr();ipAddress = request.getHeader("x-forwarded-for");if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getHeader("Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getHeader("WL-Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getRemoteAddr();if (ipAddress.equals("127.0.0.1")) {// 根据网卡取本机配置的IPInetAddress inet = null;try {inet = InetAddress.getLocalHost();} catch (UnknownHostException e) {e.printStackTrace();}ipAddress = inet.getHostAddress();}}

// 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割if (ipAddress != null && ipAddress.length() > 15) { // "***.***.***.***".length()// = 15if (ipAddress.indexOf(",") > 0) {ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));}}return ipAddress;}

使用localhost:8080访问的时候是ipv6地址，请使用127.0.0.1:8080访问服务器
