谁能给我一个java 的udp的服务器端的 代码？能够接收我的客户端的数据并转发出去给别人。
能够实现跨网段 更好
------解决方案--------------------
给你个简单的自己改造
- Java code
import java.io.*;import java.net.*;import java.util.*;public class UDPTimeServer{ private static byte[] buffer=new byte[1024]; private static DatagramPacket inPacket,outPacket; private static DatagramSocket datagramSocket; private static String s; public UDPTimeServer(){UDPS(); } public static String UDPS() { System.out.println("开始！！"); try { datagramSocket=new DatagramSocket(8000); while(true) { inPacket=new DatagramPacket(buffer,buffer.length); datagramSocket.receive(inPacket); InetAddress clientAddress=inPacket.getAddress(); int clientPort=inPacket.getPort(); s=new String(inPacket.getData(),0,inPacket.getLength()); System.out.println("地址:"+clientAddress+" 端口:"+clientPort); System.out.println("收到数据:"+s); new Rtest().jTextArea1.append(s); //datagramSocket.close(); } }catch(IOException e){e.printStackTrace();} return s; } public static void main(String args[]) { new UDPTimeServer(); }}
