java获取访问IP方法

本文主要是介绍java获取访问IP方法，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

HttpServletRequest httpServletRequest = ((ServletRequestAttributes)
RequestContextHolder.currentRequestAttributes()).getRequest();
log.info("---------------------------------------------------------");
log.info(httpServletRequest.getRequestURL()+"");
log.info(httpServletRequest.getRemoteAddr());
log.info(httpServletRequest.getQueryString());
log.info("---------------------------------------------------------");
String userIp = publicService.getRequestIp(httpServletRequest);
log.info("请求来自：{}",userIp);




public String getRequestIp(HttpServletRequest request){
String ipAddress = null;
try {
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IP
InetAddress inet = null;
try {
inet = InetAddress.getLocalHost();
} catch (Exception 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()
// = 15
if (ipAddress.indexOf(",") > 0) {
ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));
}
}
} catch (Exception e) {
ipAddress="";
}
// ipAddress = this.getRequest().getRemoteAddr();
return ipAddress;
}
