Mina入门（二）——HelloWorld

准备jar包

commons-logging、log4j、mina-core、slf4j-api、slf4j-log4j12

MinaServer

package 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.LineDelimiter;
import org.apache.mina.filter.codec.textline.TextLineCodecFactory;
import org.apache.mina.transport.socket.nio.NioSocketAcceptor;

public class MinaServer {
	
	static int port = 8024;
	
	static IoAcceptor acceptor = null;

	public static void main(String[] args) {
		acceptor = new NioSocketAcceptor();
		//设置编码过滤器
		acceptor.getFilterChain().addLast(
				"codec", new ProtocolCodecFilter(new TextLineCodecFactory(
						Charset.forName("UTF-8"),
						LineDelimiter.WINDOWS.getValue(),
						LineDelimiter.WINDOWS.getValue())));

		acceptor.getSessionConfig().setReadBufferSize(1024);
		acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10);
		acceptor.setHandler(new MyHandler());
		try {
			acceptor.bind(new InetSocketAddress(port));
		} catch (IOException e) {
			e.printStackTrace();
		}
		System.out.println("Server -> "+port+" started");
	}

}

MyHandler

package 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 MyHandler extends IoHandlerAdapter {

	@Override
	public void exceptionCaught(IoSession session, Throwable cause) throws Exception {
		System.out.println("exceptionCaught");
	}

	@Override
	public void messageReceived(IoSession session, Object message) throws Exception {
		System.out.println("messageReceived");
		Date date = new Date();
		String msg = (String)message;
		if(msg.equals("exit")) {
			session.close(true);
		}
		System.out.println("服务端接收数据："+msg);
		session.write(date);
	}

	@Override
	public void messageSent(IoSession session, Object message) throws Exception {
		System.out.println("messageSent");
	}

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

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

	@Override
	public void sessionIdle(IoSession session, IdleStatus status) throws Exception {
		System.out.println("sessionIdle");
	}

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

}

使用cmd命令窗口测试

打开cmd,输入telnet 127.0.0.1 8024 连接服务器，然后输入字符，Mina服务器接收。当输入exit时，失去连接。
