mina框架是一个基于tcp/ip,udp/ip协议的一个通信框架，他和netty都是出自一人之手，大体的结构都差不多，首先来介绍怎么建立一个mina的服务端：
一，服务端的建立:
先来看一个例子，然后我们依次来分析:
public static void main(String[] args) {
IoAcceptor acceptor = new NioSocketAcceptor() ;
acceptor.getSessionConfig().setReadBufferSize(2048) ;
acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10) ; //读写通道在10秒内无任何操作进入空闲状态
/**
* 过滤器，通过编解码器工厂来对字符串进行编解码处理
*/
acceptor.getFilterChain().addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("utf-8"),LineDelimiter.WINDOWS.getValue(),LineDelimiter.WINDOWS.getValue() )));
/*new TextLineCodecFactory( <span style="white-space:pre"> </span>Charset.forName("UTF-8")
<span style="white-space:pre"> </span>LineDelimeter.WINDOS.getValue(),
<span style="white-space:pre"> </span>LineDelimeter.WINDOS.getValue()
)*/
/*acceptor.getFilterChain().addLast("codec",
new ProtocolCodecFilter(
new ObjectSerializationCodecFactory())); */
acceptor.setHandler(new ServiceHandler()) ;
try {
acceptor.bind(new InetSocketAddress(9132));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
在这个例子中，就是启动了一个服务器端，首先IoAcceptor是服务端的一个重要的类，mina框架用的都是NIO所以，一般是new一个NioSocketAcceptor
申明建立acceptor对象后，便需要对他进行配置，配置发送字节的大小，接收消息字节的大小，多长时间无通信进入休眠，编码器，解码器（这里的编码器主要是简单的utf-8字符串编码器，后面会详细介绍编码器和解码器），注册服务器端接收消息发送消息的Handler，最后是绑定端口，这是在最后执行，配置都需要在bing之前完成，ip为默认本机ip，其中最重要的就是Handler了，下面贴出handler的代码
public class ServiceHandler extends IoHandlerAdapter{
public void sessionOpened(IoSession session )throws Exception{
}
@Override
public void exceptionCaught(IoSession session, Throwable cause)
throws Exception {
}
@Override
public void messageSent(IoSession session, Object message)throws Exception{
}
@Override
public void messageReceived(IoSession session, Object message)throws Exception{
}
@Override
public void sessionCreated(IoSession session) throws Exception{
}
@Override
public void sessionClosed(IoSession session){
}
}
}
}
可以看到handler类都需要继承IoHandlerAdapter，这是mina框架的一个Handler适配类，也就是多有的handler都要按照这个规则来写，继承后，需要覆盖父类的方法来处理连接的session以及消息，netty是通过channel来读写消息，而mina则是通过session，先来说一下这些方法的作用，
public void exceptionCaught(IoSession session, Throwable cause)这是一个异常处理的方法，如果对自己有信息，可以不要，不过一般还是添加为妙，因为也不知道为什么，确实会有一些不知道的异常出现，
public void sessionOpened(IoSession session )session打开时触发
public void messageSent(IoSession session, Object message)发送消息是触发，也就是说当你使用session.write（Object）后就会调用这个方法
public void messageReceived(IoSession session, Object message)接收消息时触发，session为连接session，message为接收到的消息，如果你发的是String，则可以通过String mess = (String)message来获取消息内容
public void sessionCreated(IoSession session)连接建立是触发
public void sessionClosed(IoSession session)连接关闭时触发
二：客户端的建立
先来看一个客户端的例子：
public void connect(String ip , String port){
IoConnector connector = null ;
connector = new NioSocketConnector();
connector.setConnectTimeoutMillis(30000);
connector.getFilterChain().addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("gbk"),LineDelimiter.WINDOWS.getValue(),LineDelimiter.WINDOWS.getValue())));
connector.setHandler(new ClientHandler());
connector.connect(new InetSocketAddress(ip , Integer.valueOf(port))) ;
this.setTitle("已连接至服务器") ;
}
mina的服务器端是申明一个IoAcceptor类，客户端则是申明一个IoConnector类，并创建一个NioSocketConnector对象，接着是对这个对象进行设置和注册，一般的设置和服务器端差不多，这里仅供参考只是设置了需要的，一行的客户端和服务器端一样需要注册一个handler来处理谁session以及接收消息，handler和服务器端的一样需要继承IoHandlerAdapter，方法也是一样，这里就不多说了，根据这些类容，我写了一个可以局域网联机的中国象棋的小游戏，主要流程是首先启动服务器端，来处理客户端的连接，和客户端之间的通信，客户端启动后会自动连接服务器，连接成功并匹配到对手后就会开始游戏，有兴趣的同学可以看一下，下面贴出代码：
