java 中获取服务器的ip地址

Java中： 

　　1、获取服务端ip

　　　　String ip = InetAddress.getLocalHost().getHostAddress();

　　2、获取客户端本机ip

　　　　

 String remoteAddr = request.getRemoteAddr();
    String forwarded = request.getHeader("X-Forwarded-For");
    String realIp = request.getHeader("X-Real-IP");
    String ip = null;
    if (realIp == null){
        if (forwarded == null) {
            ip = remoteAddr;
        } else {
            ip = remoteAddr + "/" + forwarded.split(",")[0];
        }
    } else{
        if (realIp.equals(forwarded)){
            ip = realIp;
        } else {
            if (forwarded != null) {
                forwarded = forwarded.split(",")[0];
            }
            ip = realIp + "/" + forwarded;
        }
    }
}
jsp中：　

　<%@page import="java.net.InetAddress"%> <%String ip = InetAddress.getLocalHost().getHostAddress(); %>
