mina 学习（2）

上节中通过一个简单的例子，对Mina框架有了大体的了解，在上节的基础上，看看 怎样实现客户端与服务端的通信，

废话不多说了，直接看代码：

[java] view plaincopyprint?

1. public class Test {  
2.   
3.     public static void main(String[] args) throws Exception{  
4.         SocketConnector connector = new NioSocketConnector();  
5.         IoFilter filter = new ProtocolCodecFilter(new TextLineCodecFactory());  
6.         connector.getFilterChain().addLast("vestigge", filter);  
7.         SocketAddress soketAddress = new InetSocketAddress("127.0.0.1", 5469);  
8.         connector.setHandler(new ClientHandler());  
9.         ConnectFuture future= connector.connect(soketAddress);  
10.         future.join();  
11.         if (!future.isConnected()) {  
12.             System.out.println("连接服务器失败");  
13.             return;  
14.         }  
15.         future.getSession().write("hello");  
16.     }  
17. }  

public class Test {public static void main(String[] args) throws Exception{SocketConnector connector = new NioSocketConnector();IoFilter filter = new ProtocolCodecFilter(new TextLineCodecFactory());connector.getFilterChain().addLast("vestigge", filter);SocketAddress soketAddress = new InetSocketAddress("127.0.0.1", 5469);connector.setHandler(new ClientHandler());ConnectFuture future= connector.connect(soketAddress);future.join();if (!future.isConnected()) {System.out.println("连接服务器失败");return;}future.getSession().write("hello");}}

可以看到代码与服务器端的代码很像，也是非常的简单，这就是框架的好处，不用再重复发明轮子，省了不少事，

[java] view plaincopyprint?

1. public class ClientHandler extends IoHandlerAdapter {  
2.       
3.     public void messageReceived(IoSession arg0, Object message) throws Exception {  
4.         System.out.println("收到服务器消息：" + message.toString());  
5.     }  
6.   
7.     public void exceptionCaught(IoSession arg0, Throwable arg1)  
8.             throws Exception {  
9.   
10.     }  
11. }  

public class ClientHandler extends IoHandlerAdapter {public void messageReceived(IoSession arg0, Object message) throws Exception {System.out.println("收到服务器消息：" + message.toString());}public void exceptionCaught(IoSession arg0, Throwable arg1)throws Exception {}}

效果演示：
