最问吗
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.getRemoteAddr();
if(ip.equals("127.0.0.1")){
InetAddress inet=null;
try {
inet = InetAddress.getLocalHost();
}catch (Exception e) {
e.printStackTrace();
}
ip= inet.getHostAddress();
}
}
if(ip !=null && ip.length() >15){
if(ip.indexOf(",")>0){
ip = ip.substring(0,ip.indexOf(","));
}
}
