mina

<!--StartFragment -->

 

1、下载相应的开发包http://mina.apache.org/，MINA2.0版本包含了spring开发包，还需下载其他相关包，我的工程用到的包如下图：

     

 

2、配置spring的applicationContext.xml，配置mina服务；

3、ServerHandler实现类

package com.supconit.its.server.handler;

import java.net.InetSocketAddress;
import java.util.Collections;
import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import org.apache.log4j.Logger;
import org.apache.mina.core.service.IoHandlerAdapter;
import org.apache.mina.core.session.IdleStatus;
import org.apache.mina.core.session.IoSession;


public class ServerHandler extends IoHandlerAdapter {

    private final int IDLE = 300;

     //private final Logger log = LoggerFactory .getLogger(HandlerTwo.class);
     private final Logger log = Logger.getLogger(ServerHandler.class.getName());

     public static Set<IoSession> sessions = Collections .synchronizedSet(new HashSet<IoSession>());

    /**
     *
     */
    public ServerHandler(){

    }

    @Override
    public void exceptionCaught(IoSession session, Throwable cause)
            throws Exception {
        session.close();
        //log.debug("session occured exception, so close it.");
        log.debug("session occured exception, so close it." + cause.getMessage());
    }

    @Override
    public void sessionCreated(IoSession session) {
        //
        log.debug("remote client ["+session.getRemoteAddress().toString()+"] connected.");
        session.write("Welcome");
        sessions.add(session);
    }

    @Override
    public void messageReceived(IoSession session, Object message)
            throws Exception {
        String str = message.toString();
        log.debug("Message written..." + str);
        log.debug("客户端"+((InetSocketAddress) session.getRemoteAddress()).getAddress().getHostAddress()+"连接成功！");
        /*if (str.trim().equalsIgnoreCase("quit")) {
            session.close();//
            return;
        }*/
        //Date date = new Date();
        //session.write(date.toString());//
        //session.setAttribute(remoteAddress, message);

        session.setAttribute("type", message);
        String remoteAddress = ((InetSocketAddress) session.getRemoteAddress()).getAddress().getHostAddress();
        session.setAttribute("ip", remoteAddress);

    }

    @Override
    public void sessionClosed(IoSession session) throws Exception {
         log.debug("sessionClosed.");
        sessions.remove(session);
    }

    @Override
    public void sessionIdle(IoSession session, IdleStatus status)
            throws Exception {
        log.debug("session idle, so disconnecting......");
        session.close();
        log.debug("disconnected.");
    }

    //
    @Override
    public void messageSent(IoSession session, Object message) throws Exception {
         log.debug("messageSent.");
        // disconnect an idle client
        //session.close();
    }

    @Override
    public void sessionOpened(IoSession session) throws Exception {
        log.debug("sessionOpened.");
        //
        session.getConfig().setIdleTime(IdleStatus.BOTH_IDLE, IDLE);
    }

}

4、过滤器ServerCodeFactory

package com.supconit.its.server.handler;

import java.nio.charset.Charset;

import org.apache.mina.core.session.IoSession;
import org.apache.mina.filter.codec.ProtocolCodecFactory;
import org.apache.mina.filter.codec.ProtocolDecoder;
import org.apache.mina.filter.codec.ProtocolEncoder;
import org.apache.mina.filter.codec.textline.LineDelimiter;
import org.apache.mina.filter.codec.textline.TextLineDecoder;
import org.apache.mina.filter.codec.textline.TextLineEncoder;

public  class ServerCodeFactory implements ProtocolCodecFactory {

        private final TextLineEncoder encoder;
        private final TextLineDecoder decoder;
        /*final static char endchar = 0x1a;*/
        final static char endchar = 0x0d;
        public ServerCodeFactory() {
            this(Charset.forName("gb2312"));
        }
        public ServerCodeFactory(Charset charset) {
             encoder = new TextLineEncoder(charset, LineDelimiter.UNIX);
             decoder = new TextLineDecoder(charset, LineDelimiter.AUTO);
             }

        @Override
        public ProtocolDecoder getDecoder(IoSession session) throws Exception {
            // TODO Auto-generated method stub
            return decoder;
        }
        @Override
        public ProtocolEncoder getEncoder(IoSession session) throws Exception {
            // TODO Auto-generated method stub
            return encoder;
        }
        public int getEncoderMaxLineLength() {
            return encoder.getMaxLineLength();
        }
        public void setEncoderMaxLineLength(int maxLineLength) {
            encoder.setMaxLineLength(maxLineLength);
        }
        public int getDecoderMaxLineLength() {
            return decoder.getMaxLineLength();
        }
        public void setDecoderMaxLineLength(int maxLineLength) {
            decoder.setMaxLineLength(maxLineLength);
        }

}

5、启动spring+mina socket server；

package com.supconit.its.server.test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        ClassPathXmlApplicationContext ct =    new ClassPathXmlApplicationContext("applicationContext.xml");

    }

}

6、客户端测试ClintTest

package com.supconit.its.server.test;

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

import org.apache.mina.core.future.ConnectFuture;
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.NioSocketConnector;

import com.supconit.its.server.handler.ServerHandler;



public class ClintTest {

    /**
     * @param args
     */
    public static void main(String[] args) {
        NioSocketConnector connector = new NioSocketConnector();
        connector.getFilterChain().addLast( "logger", new LoggingFilter() );
        //connector.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "GBK" )))); //
        connector.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( )));
        connector.setConnectTimeout(1);
        connector.setHandler(new ServerHandler());//
        ConnectFuture cf = connector.connect(
        new InetSocketAddress("127.0.0.1", 1235));//
        cf.awaitUninterruptibly();//
        cf.getSession().write("hello,测试！");//
        //cf.getSession().write("quit");//
        cf.getSession().close();
        cf.getSession().getCloseFuture().awaitUninterruptibly();//
        connector.dispose();

    }

}
