• mina是一個基於javaNio網路通訊應用框架,使用mina可以輕鬆的搭建伺服器，接下來將使用mina搭建一個小型的服務端

• 原始碼–MinaServer.java

        //設定進入空閒狀態的時間 10毫秒
        acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10);

        } catch (IOException e) {

• 原始碼–MinaHandle.java

package server;

import java.util.Date;

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

public class MinaHandle implements IoHandler {

    @Override
    public void exceptionCaught(IoSession arg0, Throwable arg1) throws Exception {
        System.out.println("exceptionCaught");

    }

    @Override
    public void inputClosed(IoSession arg0) throws Exception {
        System.out.println("inputClosed");

    }

    @Override
    public void messageReceived(IoSession sesion, Object msg) throws Exception {
        System.out.println("接收到："+(String)msg);
        //如果接收到exit就關閉連線
        if("exit".equals((String)msg)){
            sesion.close();
        }
        else{
        Date date = new Date();
        sesion.write("\n當前系統時間"+date+"\n");
        }



    }

    @Override
    public void messageSent(IoSession arg0, Object arg1) throws Exception {
        System.out.println("messageSent");

    }

    @Override
    public void sessionClosed(IoSession arg0) throws Exception {
        System.out.println("sessionClosed");

    }

    @Override
    public void sessionCreated(IoSession arg0) throws Exception {
        System.out.println("sessionCreated");

    }

    @Override
    public void sessionIdle(IoSession arg0, IdleStatus arg1) throws Exception {
        System.out.println("sessionIdle");

    }

    @Override
    public void sessionOpened(IoSession arg0) throws Exception {
        System.out.println("sessionOpened");

    }

}

• 通過telnet訪問伺服器,每當接收到客戶端傳送的訊息，便會返回系統當前時間，當接收到exit則關閉連線：
