Java udp服务器不接受带有mina的消息

我在测试中使用mina udp，服务器和客户端都在同一台计算机上，客户端和服务器运行时不会抛出异常，但服务器无法接收消息。 代码是

public class SmsClient extends IoHandlerAdapter {

    private final static Logger logger = LoggerFactory.getLogger("sms");

    private IoSession session;

    private IoConnector connector;

    public SmsClient(final String phone, final String content) {
        connector = new NioDatagramConnector();
        DefaultIoFilterChainBuilder chain = connector.getFilterChain();
        chain.addLast("myChin", new ProtocolCodecFilter(
                new TextLineCodecFactory(Charset.forName("UTF-8"))));
        chain.addLast("logger", new LoggingFilter());
        connector.setHandler(this);

         String ip = "127.0.0.1";
        String port = "8080";


        ConnectFuture connFuture = connector.connect(new InetSocketAddress(ip,
                Integer.valueOf(port)));

        connFuture.awaitUninterruptibly();
        connFuture.addListener(new IoFutureListener<ConnectFuture>() {
            public void operationComplete(ConnectFuture future) {
                if (future.isConnected()) {
                    session = future.getSession();
                    try {
                        sendData(phone, content);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                } else {
                    try {
                        throw new Exception("connect failed....");
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }
        });
    }

    private void sendData(String phone, String content)
            throws InterruptedException {


        String s = "K&" + phone + "&" + content;


        logger.info(s);

        Charset c = Charset.forName("utf-8");

        byte[] b = s.getBytes(c);
        IoBuffer buffer = IoBuffer.allocate(b.length, false);
        buffer.put(b);
        buffer.flip();
        session.write(buffer);
    }

    @Override
    public void exceptionCaught(IoSession session, Throwable cause)
            throws Exception {
        cause.printStackTrace();
        System.out.println("exceptionCaught.................");
        session.close(true);
    }

    @Override
    public void messageReceived(IoSession session, Object message)
            throws Exception {
        System.out.println("messageReceived................."+message);

    }

  public static void main(String[] args) {
    new SmsClient("18610413435", "hiii");
  }
}

}

你能帮我找出哪里的密码错了吗？

谢谢你的建议和帮助

要使此示例正常工作，请从SmsServer类的方法initUDPServer中删除ProtocolCodeFilter行：

        chain.addLast("encode", new ProtocolCodecFilter(
            new TextLineCodecFactory(Charset.forName("UTF-8"))
            ));

并从SmsClient类的构造函数中删除ProtocolCodeFilter行：

    chain.addLast("myChin", new ProtocolCodecFilter(
            new TextLineCodecFactory(Charset.forName("UTF-8"))));

通过此修改，以下是客户端日志：
