服务器端用了Mina 是不是客户端也要用Mina才能通讯？

Mina长连接框架实现Android客户端与服务器端通信一、概述 Apache Mina Server 是一个网络通信应用框架，也就是说，它主要是对基于TCP/IP、UDP/IP协议栈的通信框架（当然，也可以提供JAVA 对象的序列化服务、虚拟机管道通信服务等），Mina 可以帮助我们快速开发高性能、高扩展性的网络通信应用，Mina 提供了事件驱动、异步（Mina 的异步IO 默认使用的是JAVA NIO 作为底层支持）操作的编程模型阅读详情

服务器端代码





private static Logger log = Logger.getLogger(ServerMain.class.getName());

	

	private static final int PORT = 11104;



	public static void main(String[] args){

		

		IoAcceptor acceptor;

		try{

			acceptor = new NioSocketAcceptor();

			

			DefaultIoFilterChainBuilder builder = acceptor.getFilterChain();

			

			 //过滤器的位置很重要，在这里因为放到了第一个位置，它会记录原始字节码数据  

	        LoggingFilter lf = new LoggingFilter();   

	        builder.addLast("logger", lf); 

			

			//设置解码器

			builder.addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(

					Charset.forName("GBK"))));

			

			//进行配置信息的设置  

	        acceptor.getSessionConfig().setReadBufferSize(10);

			

			//session配置

			IoSessionConfig sessionConfig = acceptor.getSessionConfig();

			//sessionConfig.setMaxReadBufferSize(1024*100);

			//读写通道10秒后无操作进入空闲状态

			sessionConfig.setIdleTime(IdleStatus.BOTH_IDLE, 10);

			

			//设置处理器 

			acceptor.setHandler(new ServerHandler());

			

			//绑定本地端口

			acceptor.bind(new InetSocketAddress(PORT));

		}catch(Exception e){

			e.printStackTrace();

		}

		

		log.info("main thread exit!");

	}





public class ServerHandler extends IoHandlerAdapter {

	

	private final Logger log = Logger.getLogger(ServerHandler.class.getName());



	@Override

	public void sessionCreated(IoSession session) throws Exception {

		log.log(Level.INFO, "........................session created");

		super.sessionCreated(session);

	}



	@Override

	public void sessionOpened(IoSession session) throws Exception {

		log.log(Level.INFO, "........................session opened");

		session.write("12345");

		super.sessionOpened(session);

	}



	@Override

	public void sessionClosed(IoSession session) throws Exception {

		log.log(Level.INFO, "........................session closed");

		super.sessionClosed(session);

	}



	@Override

	public void sessionIdle(IoSession session, IdleStatus status)

			throws Exception {

		log.log(Level.INFO, "........................session idle");

		super.sessionIdle(session, status);

	}



	@Override

	public void exceptionCaught(IoSession session, Throwable cause)

			throws Exception {

		log.log(Level.INFO, "........................session exception");

		log.log(Level.WARNING,cause.getMessage());

		super.exceptionCaught(session, cause);

	}



	@Override

	public void messageReceived(IoSession session, Object message)

			throws Exception {

		log.log(Level.INFO, "........................message received");

		log.log(Level.INFO, message.toString());

		super.messageReceived(session, message);

	}



	@Override

	public void messageSent(IoSession session, Object message) throws Exception {

		log.log(Level.INFO, "........................message sent");

		super.messageSent(session, message);

	}



	

	

}

客户端代码





	public static void main(String[] args) {



		try {

			Socket socket = new Socket("localhost",11104);

			

			OutputStream os = socket.getOutputStream();

			

			os.write("abcdef".getBytes());

			os.flush();

		} catch (UnknownHostException e) {

			// TODO Auto-generated catch block

			e.printStackTrace();

		} catch (IOException e) {

			// TODO Auto-generated catch block

			e.printStackTrace();

		}

		

		

		

		while(true){

			

		}



	}

日志：

2011-9-28 17:42:03 ServerMain main
信息: main thread exit!
log4j:WARN No appenders could be found for logger (org.apache.mina.filter.logging.LoggingFilter).
log4j:WARN Please initialize the log4j system properly.
2011-9-28 17:42:09 ServerHandler sessionCreated

2011-9-28 17:42:09 ServerHandler messageSent

从日志上可以看出
客户端是连上了的，但是往服务器端发数据部成功，服务器往客户端发数据是可以的。例子很简单但却找不到问题出在哪里。
麻烦大家帮忙看看。
