Apache MINA 基于TCP实例

1、基于TCP/IP服务端

server：

import java.net.InetSocketAddress;
import java.nio.charset.Charset;

import org.apache.mina.core.session.IdleStatus;
import org.apache.mina.core.service.IoAcceptor;
import org.apache.mina.filter.codec.ProtocolCodecFilter;
import org.apache.mina.filter.codec.textline.TextLineCodecFactory;
import org.apache.mina.filter.logging.LoggingFilter;
import org.apache.mina.transport.socket.nio.NioSocketAcceptor;

public class MinaTimeServer
{
    public static void main( String[] args ) throws IOException
    {
        IoAcceptor acceptor = new NioSocketAcceptor();//创建SocketAcceptor，监听连接进来的连接
 　　　　acceptor.getFilterChain().addLast( "logger", new LoggingFilter() );//添加Log过滤器

        acceptor.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ))));//添加编码过滤器
        acceptor.setHandler(  new TimeServerHandler() );//设置业务逻辑处理类
        acceptor.getSessionConfig().setReadBufferSize( 2048 );//设置读取数据的缓冲区
        acceptor.getSessionConfig().setIdleTime( IdleStatus.BOTH_IDLE, 10 );
        acceptor.bind( new InetSocketAddress(PORT) );//绑定监听的端口号

} }

Server Handler：

import java.util.Date;

import org.apache.mina.core.session.IdleStatus;
import org.apache.mina.core.service.IoHandlerAdapter;
import org.apache.mina.core.session.IoSession;

public class TimeServerHandler extends IoHandlerAdapter
{
    @Override
    public void exceptionCaught( IoSession session, Throwable cause ) throws Exception
    {
        cause.printStackTrace();
    }
    @Override
    public void messageReceived( IoSession session, Object message ) throws Exception
    {
        String str = message.toString();
        if( str.trim().equalsIgnoreCase("quit") ) {
            session.close();
            return;
        }
        Date date = new Date();
        session.write( date.toString() );
        System.out.println("Message written...");
    }
    @Override
    public void sessionIdle( IoSession session, IdleStatus status ) throws Exception
    {
        System.out.println( "IDLE " + session.getIdleCount( status ));
    }
}

2、基于TCP/IP客户端

clinet

public static void main(String[] args) throws Throwable {
    NioSocketConnector connector = new NioSocketConnector();//创建一个连接器
    connector.setConnectTimeoutMillis(CONNECT_TIMEOUT);

　　//创建一个过滤器链
    if (USE_CUSTOM_CODEC) {
    connector.getFilterChain().addLast("codec",
        new ProtocolCodecFilter(new SumUpProtocolCodecFactory(false)));
    } else {
        connector.getFilterChain().addLast("codec",
            new ProtocolCodecFilter(new ObjectSerializationCodecFactory()));
    }

    connector.getFilterChain().addLast("logger", new LoggingFilter());
    connector.setHandler(new ClientSessionHandler(values));
    IoSession session;

    for (;;) {
        try {
            ConnectFuture future = connector.connect(new InetSocketAddress(HOSTNAME, PORT));
            future.awaitUninterruptibly();
            session = future.getSession();
            break;
        } catch (RuntimeIoException e) {
            System.err.println("Failed to connect.");
            e.printStackTrace();
            Thread.sleep(5000);
        }
    }

    // wait until the summation is done
    session.getCloseFuture().awaitUninterruptibly();
    connector.dispose();
}
