淺談小偷程序之Java

題外話：如果用EditPlus作為編輯器的話如果保存的格式默認(rèn)為unicode的話那么在里面寫(xiě)中文用resin作為應(yīng)用服務(wù)器的話就可能出現(xiàn)報(bào)500 Servlet錯(cuò)誤哦！主要是因?yàn)榫幋a的問(wèn)題！

所以要注意好頁(yè)面的編碼問(wèn)題！有時(shí)間我得作一個(gè)專題專門來(lái)討論一下有關(guān)JSP中編碼的問(wèn)題哦！

題外話二：研究如何讀LINUX的服務(wù)器IP

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

public class GetIp {
    public static void main(String[] args){
        String ip = null;
        GetIp test = new GetIp();
        try{
            ip = test.getLocalSiteIP();
        }catch(Exception e){
            System.out.print(e.toString());
        }
        System.out.print(ip);
    }
    private   String   getLocalSiteIP()   throws   Exception   {
          String   siteString   =   "";
          Enumeration   netInterfaces   =   NetworkInterface.getNetworkInterfaces();
          while   (netInterfaces.hasMoreElements())   {
                NetworkInterface   ni   =   (NetworkInterface)   netInterfaces.nextElement();
                InetAddress   ip   =   (InetAddress)   ni.getInetAddresses().nextElement();
                if   (ip.isSiteLocalAddress()   &&   !ip.isLoopbackAddress()   &&
                      ip.getHostAddress().indexOf(":")   ==   -1)   {
                      siteString   =   ip.getHostAddress();
                }
        }
        return   siteString;
    }
}
