java获取本地IP和服务器IP

java获取IP地址

• 获取本地IP地址

  //这种方法能不能在Linux服务器上直接获取IP有待验证
  String address = InetAddress.getLocalHost().getHostAddress().toString();

• 获取服务器IP地址(针对nginx)

  package com.utils;
   
  import javax.servlet.http.HttpServletRequest;
   
  public class GetIP {
  	/**
  	*Auther:呐喊
  	*Function:获取客户端IP地址，针对Nginx等反代作处理
  	*Date:2016-11-01
  	*URL:http://www.htcdc.com
  	*/
  	public String getIP(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("X-Real-IP");
  		}
  		if(ip==null || ip.length()==0 || "unknown".equalsIgnoreCase(ip)){
  			ip=request.getRemoteAddr();
  		}
  		return ip;
  	}
