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();

        }

    }

}
