针对局域网IM飞秋(feiq)的开发总结

先上代码了，通过java代码群发feiq消息：
package com.triman.constant;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Date;

public class SendFeiQ  {
    public void sendMsgToFeiQ(String content){            
        DatagramSocket ds;
        try {
            ds = new DatagramSocket();
            String name="投票系统管理员";
            String host="triman";
            long IPMSG_SENDMSG=0x00000020;        
            byte[] buffer = ("1:" + new Date().getTime() + ":" + name + ":"+ host + ":" + IPMSG_SENDMSG + ":" + content).getBytes("gbk");        
            DatagramPacket dp=new DatagramPacket(buffer, buffer.length,InetAddress.getByName("192.168.100.255"),2425); 
            ds.send(dp);
            ds.close();
        } catch (SocketException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (UnknownHostException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }    
    }
}
