mina教程

关于mina介绍这里不做阐述.....

我们先做一个关于mina的helloworld

首先先下载mina包:http://mina.apache.org/ (如果你已经下载,此步骤忽略)

下载下来以后,我们主要是使用里面jar包

 

接下来打开eclipse,建立Java Project

引入jar包,根据官方文档提示:

我们所引入的jar文件为:

继续,开始写代码,我们先写一个server:

package org.xs.mina;

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

import org.apache.mina.core.service.IoAcceptor;
import org.apache.mina.core.session.IdleStatus;
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 {
    private static final int PORT = 9123;
	public static void main(String[] args) {
		//socket接收器
		IoAcceptor acceptor = new NioSocketAcceptor();

		//添加日志记录
		acceptor.getFilterChain().addLast("logger", new LoggingFilter());
		//添加编码解码器 
		acceptor.getFilterChain().addLast("codec",new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));
		//添加处理器(用于接收数据后处理处理数据逻辑) 
		acceptor.setHandler(  new TimeServerHandler() );
		//设置读取数据缓存单位byte  
		acceptor.getSessionConfig().setReadBufferSize( 2048 );
		//设置多长时间后接收器开始空闲
        acceptor.getSessionConfig().setIdleTime( IdleStatus.BOTH_IDLE, 10 );
        try {
        	//绑定某个端口,作为数据入口  
			acceptor.bind( new InetSocketAddress(PORT) );
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

 

定义处理器:

package org.xs.mina;

import java.util.Date;

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


public class TimeServerHandler extends IoHandlerAdapter {

	//捕获异常
	@Override
    public void exceptionCaught( IoSession session, Throwable cause ) throws Exception
    {
        cause.printStackTrace();
    }
	//消息接收
    @Override
    public void messageReceived( IoSession session, Object message ) throws Exception
    {
        String str = message.toString();
        if( str.trim().equalsIgnoreCase("quit") ) {
            session.close();
            return;
        }
        System.out.println("my message>>>>>>>>>>"+str);
        Date date = new Date();
        session.write( date.toString() );
    }
    //会话空闲
    @Override
    public void sessionIdle( IoSession session, IdleStatus status ) throws Exception
    {
        System.out.println( "IDLE " + session.getIdleCount( status ));
    }
}

 

接下来,我们把server类,run起来,我们模拟下tcp调用,打开cmd命令行:C:\Users\xiao>telnet 127.0.0.1 9123

 

连接服务器,输入hello...

 

客户端:

服务端:
