Mina框架构建一个HelloWorld

Mina第一个HelloWorld程序:

服务端程序：

Minaserver.java: 

 1 public class MinaServer { 2     private IoAcceptor ioAcceptor; 3      4     public MinaServer(int port) 5     { 6         ioAcceptor = new NioSocketAcceptor(); 7         try { 8             //设置处理器 9             ioAcceptor.setHandler(new MyHandler());10             //绑定端口11             ioAcceptor.bind(new InetSocketAddress(port));12             //规定协议，设定过滤，这里用TextLineCodecFactory文本协议13             ioAcceptor.getFilterChain().addLast("test", new ProtocolCodecFilter(new TextLineCodecFactory()));14         } catch (IOException e) {15             e.printStackTrace();16         }17     }18 }

 MyHandler.java:  (服务端接收消息后的业务逻辑处理)

1 public class MyHandler extends IoHandlerAdapter {2     /**接收到信息后进行逻辑处理*/3     @Override4     public void messageReceived(IoSession session, Object message)5             throws Exception {6         String getmessage = message.toString();7         System.out.println(getmessage);8     }9 }

 

客户端程序：

MinaClient.java:

 1 public class MinaClient { 2     private IoConnector ioConnector; 3      4     public MinaClient(String host, int port) 5     { 6         ioConnector = new NioSocketConnector(); 7         //过滤信息，封装成文本格式输出 8         ioConnector.getFilterChain().addLast("test", new ProtocolCodecFilter(new TextLineCodecFactory())); 9         10         ioConnector.setHandler(new ClientHandler("Hello world!"));11         ioConnector.connect(new InetSocketAddress(host, port));12     }13 }

ClientHandler.java:

 1 public class ClientHandler extends IoHandlerAdapter { 2     //发送给服务端的消息 3     private String sendToServer; 4      5     public ClientHandler(String words) 6     { 7         sendToServer = words; 8     } 9     10     @Override11     public void sessionOpened(IoSession session) throws Exception {12         session.write(sendToServer);13     }14 }
