mina客户端程序

定义Client类用于连接服务端，并向服务端发送消息：

public class MinaTimeClient { 
  public static void main(String[] args) { 
    // 创建客户端连接器. 
    NioSocketConnector connector = new NioSocketConnector(); 
    connector.getFilterChain().addLast( "logger", new LoggingFilter() ); 
    connector.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" )))); //设置编码过滤器 
     connector.setConnectTimeout(30); 
    connector.setHandler(new TimeClientHandler());//设置事件处理器 
     ConnectFuture cf = connector.connect(new InetSocketAddress("127.0.0.1", 9123));//建立连接 
     cf.awaitUninterruptibly();//等待连接创建完成 
     cf.getSession().write("hello");//发送消息 
     cf.getSession().write("quit");//发送消息 
     cf.getSession().getCloseFuture().awaitUninterruptibly();//等待连接断开 
     connector.dispose(); 
  } 
}
