Answer 1

我写的发送的代码
public class UdpService extends Service{
// private static final int DATA_LEN = 4096;
private DatagramSocket socket;

public UdpService(){
    try{
        socket = new DatagramSocket();
    }catch(IOException e){
        e.printStackTrace();
    }
}
public DatagramSocket getDatagramSocket(){
    return this.socket;
}
public void sendMsg(String msg, InetSocketAddress dest){
    try{
        byte[] buffer = msg.getBytes();
        DatagramPacket packet = new DatagramPacket(buffer, buffer.length, dest);
        socket.send(packet);
    }catch(IOException e){
        e.printStackTrace();
        if(socket != null){
            socket.close();
        }
        System.out.println("网络异常");
        System.exit(1);
    }
}
public void sendMsg(String msg, String dest){
    // System.out.println(dest);
    InetSocketAddress address = ComUtil.strToAddress(dest);
    sendMsg(msg, address);
}

}
