1、服务器端

public class MinaServer {
   public static final int PORT=1234;
   private static Logger log = Logger.getLogger(MinaServer.class);

   public static void main(String[] args) {
       try{
       //创建一个非阻塞的server
       IoAcceptor acceptor = new NioSocketAcceptor();

       //log过滤器
       acceptor.getFilterChain().addLast("logger", new LoggingFilter());

       //编码解码过滤器
        acceptor.getFilterChain().addLast( "codec",
                        new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));

        //设置通道占用时间
        acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10);

        //业务逻辑对象
        acceptor.setHandler(new MinaServerHandler());

        //端口邦定
       acceptor.bind(new InetSocketAddress(PORT));

       log.info("MESSAGE:SERVER MESSAGE:FRONT END SERVER IS LAUNCH,LISTENER PORT:" + PORT);
       } catch (IOException e) {
           e.printStackTrace();
       }
   }
}

2、服务器的业务逻辑处理

public class MinaServerHandler extends IoHandlerAdapter {

   private final Logger logger =Logger.getLogger(MinaServerHandler.class);
   boolean sendFlag=false;
    private static String sendMsg="Hello Client,server receive message...";

   @Override
    public void sessionOpened(IoSession session) {
            logger.info("==================================MESSAGE：SERVICE START=============================");
            session.setAttribute("Values: ");
    }

    @Override
    public void messageReceived(IoSession session, Object message) {
           sendFlag=true;
           logger.info("Message received in the server..");
            logger.info("Message is: " + message.toString());
            if(sendFlag){
               try {
//                   messageSent(session,MinaClient02.getMsgLength(sendMsg).getBytes());
                   messageSent(session,sendMsg);
               } catch (Exception e) {
                   e.printStackTrace();
               }
            }
    }

    @Override
    public void sessionIdle(IoSession session, IdleStatus status) {
            logger.info("Disconnecting the idle.");
            session.close(true);
    }


    @Override
   public void messageSent(IoSession session, Object message) throws Exception {
       logger.info("Message Sent....");
       session.write(message);
       session.close(true);
   }

   @Override
    public void exceptionCaught(IoSession session, Throwable cause) {
            session.close(true);
    }

   @Override
   public void sessionClosed(IoSession session) throws Exception {
       logger.info("==================================MESSAGE：SERVICE END=============================");
   }

}

3、客户端

public class MinaClient {

   private static String sendMsg="respMsg=中华人民共和国&respTime=20121105093922&merId=123456789012345&merAbbr=CUPDATA IC TEST3&orderNumber=IC13520795375152872&qid=013746&orderAmount=000000000001&orderCurrency=156&settleAmount";
   private static final int PORT = 1234;
   public static void main(String[] args) {

       //客户端对象
       IoConnector connector = new NioSocketConnector();

       //可读缓存的大小
        connector.getSessionConfig().setReadBufferSize(2048);

        //log过滤器
        connector.getFilterChain().addLast("logger", new LoggingFilter());

        //编码解码过滤器
        connector.getFilterChain().addLast("codec",
                        new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));

        //业务逻辑处理对象
        connector.setHandler(new MinaClientHandler());

        //建立连接
        ConnectFuture future = connector.connect(new InetSocketAddress("localhost", PORT));

        future.awaitUninterruptibly();

        if (!future.isConnected()) {
                return;
        }

        //允许读操作
        future.getSession().getConfig().setUseReadOperation(true);

        //写消息
        future.getSession().write(getSendMsgLen(sendMsg));

        //等待操作的完成
        future.getSession().getCloseFuture().awaitUninterruptibly();

        System.out.println("After Writing");

        //连接关闭
        connector.dispose();

   }
}

4、客户端的业务逻辑处理

public class MinaClientHandler extends IoHandlerAdapter {
   private final Logger logger = Logger.getLogger(getClass());

     private boolean finished;
     private String values;

     public MinaClientHandler() {
   }

   public MinaClientHandler(String values) {
             this.values = values;
     }


   public boolean isFinished() {
             return finished;
     }


     @Override
     public void messageReceived(IoSession session, Object message) {

             logger.info("Message received in the client..");
             logger.info("Message is: " + message.toString());
     }

     @Override
     public void exceptionCaught(IoSession session, Throwable cause) {
             session.close(true);
     }

}
