获取当前人IP地址

/**
* 获取访问的IP地址
* @date 2018年11月26日上午11:31:49

public String getIpAddr(HttpServletRequest request){ 
String 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") || ipAddress.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(); 
} 
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(",")); 
} 
} 
return ipAddress; 
}

只需要把request的参数传进去就可以拿到IP了。

使用场景：日志记录
