在使用springboot时，需要获取访问客户端的IP地址，
//获取客户端IP地址private String getIpAddress() {String ip = request.getHeader("x-forwarded-for");if(ip == null || ip.length() == 0 || "unknow".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.getRemoteAddr ();if (ip.equals ("127.0.0.1")) {//根据网卡取本机配置的IPInetAddress inet = null;try {inet = InetAddress.getLocalHost ();} catch (Exception e) {e.printStackTrace ();}ip = inet.getHostAddress ();}}// 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 (ip != null && ip.length () > 15) {if (ip.indexOf (",") > 0) {ip = ip.substring (0, ip.indexOf (","));}}return ip;}
在windows7 使用localshot访问时，获取到的IP地址为0:0:0:0:0:1 原因是localhost解析不出来 需要使用正常的IP地址访问时，则可正确的得到访问client端的IP地址
