Mina客户端Client和Server对象传输demo

最基本的那个例子，也就是官网上的那个demo，我就不说了...

1、demo地址：http://weavesky.com/2010/02/19/mina-article-2/ 

但是我们实际项目中，肯定比不是如此的传输一两个数据的，我们需要传对象...老样子在此上传demo的源代码

此例子参考了himi的博文，博文地址：http://www.himigame.com/category/apache-mina

官网网站：http://mina.apache.org/mina-project/userguide/user-guide-toc.html

2、依赖的包：

mina-core-2.0.7.jar

slf4j-api-1.7.2.jar

slf4j-jdk14-1.7.2.jar

slf4j-log4j12-1.7.2.jar

3、客户端和服务端目录结构图：

一、Server

1、MinaServer

package com.potter;import java.io.IOException;import java.net.InetSocketAddress;import java.nio.charset.Charset;import org.apache.mina.core.filterchain.DefaultIoFilterChainBuilder;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.transport.socket.SocketAcceptor;import org.apache.mina.transport.socket.nio.NioSocketAcceptor;public class MinaServer {private static final int bindPort=8899;public static void main(String[] args){SocketAcceptor acceptor = new NioSocketAcceptor();DefaultIoFilterChainBuilder chain = acceptor.getFilterChain();ProtocolCodecFilter filter= new ProtocolCodecFilter(new HCoderFactory(Charset.forName("UTF-8"))); //添加编码过滤器 处理乱码问题、编码问题chain.addLast("objectFilter",filter);//设置核心消息业务处理器acceptor.setHandler(new MinaServerHanlder());try {// 绑定端口acceptor.bind(new InetSocketAddress(bindPort));} catch (IOException e) { System.out.println("Mina Server start for error!"+bindPort);e.printStackTrace();}System.out.println("Mina Server run done! on port:"+bindPort);}}

2、MinaServerHanlder

package com.potter;import org.apache.mina.core.service.IoHandlerAdapter;import org.apache.mina.core.session.IoSession;public class MinaServerHanlder extends IoHandlerAdapter {private int count = 0;public void sessionCreated(IoSession session) {System.out.println("新客户端连接");}@Overridepublic void sessionOpened(IoSession session) throws Exception {// TODO Auto-generated method stubcount++;System.out.println("第 " + count + " 个 client 登陆！address： : "+ session.getRemoteAddress());}@Overridepublic void sessionClosed(IoSession session) throws Exception {// TODO Auto-generated method stubsession.close();System.out.println("I'm Client &&  I closed!");}@Overridepublic void messageReceived(IoSession session, Object message)throws Exception {// TODO Auto-generated method stubPlayerAccount_Entity ho = (PlayerAccount_Entity) message;System.out.println("Client message="+ho.getId()+ho.getName()+ho.getEmailAdress()+ho.getSex());         //     session.write(ho);}}

3、HCoderFactory

package com.potter;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;public class HCoderFactory implements ProtocolCodecFactory {     private final HEncoder encoder;    private final HDecoder decoder;     public HCoderFactory() {this(Charset.defaultCharset());    }     public HCoderFactory(Charset charSet) {        this.encoder = new HEncoder(charSet);        this.decoder = new HDecoder(charSet);    }@Overridepublic ProtocolDecoder getDecoder(IoSession arg0) throws Exception {// TODO Auto-generated method stubreturn decoder;}@Overridepublic ProtocolEncoder getEncoder(IoSession arg0) throws Exception {// TODO Auto-generated method stubreturn encoder;}     }

4、HEncoder

package com.potter;import java.nio.charset.Charset;import java.nio.charset.CharsetEncoder;import org.apache.mina.core.buffer.IoBuffer;import org.apache.mina.core.session.IoSession;import org.apache.mina.filter.codec.ProtocolEncoder;import org.apache.mina.filter.codec.ProtocolEncoderOutput;public class HEncoder implements ProtocolEncoder{private final Charset charset;public HEncoder(Charset charset) {this.charset = charset;}@Overridepublic void encode(IoSession session, Object message,ProtocolEncoderOutput out) throws Exception {CharsetEncoder ce = charset.newEncoder();PlayerAccount_Entity paEntity = (PlayerAccount_Entity) message;IoBuffer buffer = IoBuffer.allocate(100).setAutoExpand(true);buffer.putInt(paEntity.getId());buffer.putString(paEntity.getName(), ce);buffer.putString(paEntity.getEmailAdress(), ce);buffer.putInt(paEntity.getSex());buffer.flip();out.write(buffer);}@Overridepublic void dispose(IoSession session) throws Exception {// TODO Auto-generated method stub}}

5、HDecoder

package com.potter;import java.nio.charset.Charset;import java.nio.charset.CharsetDecoder;import org.apache.mina.core.buffer.IoBuffer;import org.apache.mina.core.session.IoSession;import org.apache.mina.filter.codec.CumulativeProtocolDecoder;import org.apache.mina.filter.codec.ProtocolDecoderOutput;public class HDecoder extends CumulativeProtocolDecoder {private final Charset charset;public HDecoder(Charset charset) {this.charset = charset;}@Overrideprotected boolean doDecode(IoSession arg0, IoBuffer message,ProtocolDecoderOutput arg2) throws Exception {CharsetDecoder cd = charset.newDecoder();int id=0;if(message.remaining()>=4){id=message.getInt();}String name = message.getString(cd);String emailAdress=message.getString(cd);int sex=0;if(message.remaining()>=4){sex=message.getInt();}PlayerAccount_Entity paEntity = new PlayerAccount_Entity(id,name,emailAdress,sex);arg2.write(paEntity);return true;}}

6、PlayerAccount_Entity

package com.potter;public class PlayerAccount_Entity{private int id;    private String name;    private String emailAdress;    private int sex;// 0=man 1=womanpublic PlayerAccount_Entity(int id,String name,String emailAdress,int sex){this.id=id;this.name=name;this.emailAdress=emailAdress;this.sex=sex;} public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getEmailAdress() {return emailAdress;}public void setEmailAdress(String emailAdress) {this.emailAdress = emailAdress;}public int getSex() {return sex;}public void setSex(int sex) {this.sex = sex;}}

二、Client

1、MinaClient

package com.potter;import java.net.InetSocketAddress;import java.nio.charset.Charset;import org.apache.mina.core.filterchain.DefaultIoFilterChainBuilder;import org.apache.mina.core.future.ConnectFuture;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.transport.socket.nio.NioSocketConnector;public class MinaClient {private static final int bindPort=8899;public static void main(String[] args){// 创建一个socket连接      NioSocketConnector connector=new NioSocketConnector();// 获取过滤器链        DefaultIoFilterChainBuilder chain=connector.getFilterChain();ProtocolCodecFilter filter= new ProtocolCodecFilter(new HCoderFactory(Charset.forName("UTF-8"))); // 添加编码过滤器 处理乱码、编码问题  chain.addLast("objectFilter",filter);// 消息核心处理器     connector.setHandler(new MinaClientHanlder());// 设置链接超时时间     connector.setConnectTimeoutCheckInterval(30);// 连接服务器，知道端口、地址    ConnectFuture cf = connector.connect(new InetSocketAddress("localhost",bindPort));// 等待连接创建完成    cf.awaitUninterruptibly();cf.getSession().getCloseFuture().awaitUninterruptibly();connector.dispose();}}

 

2、MinaClientHanlder

package com.potter;import org.apache.mina.core.service.IoHandlerAdapter;import org.apache.mina.core.session.IoSession;public class MinaClientHanlder extends IoHandlerAdapter{public void sessionOpened(IoSession session) throws Exception { PlayerAccount_Entity ho = new PlayerAccount_Entity(10,"Potter","[e-mail]",0);     session.write(ho);    }@Overridepublic void messageReceived(IoSession session, Object message)throws Exception {PlayerAccount_Entity ho = (PlayerAccount_Entity) message;        System.out.println("Server Say:name:" + ho.getName());}@Overridepublic void sessionClosed(IoSession session) throws Exception {// TODO Auto-generated method stubsession.close();}}

好了，共同的就不穿了....
