服务端：

package com.mina.demo;import java.io.IOException;import java.net.InetSocketAddress;import java.nio.charset.Charset;import org.apache.mina.common.ByteBuffer;import org.apache.mina.common.IoAcceptor;import org.apache.mina.common.SimpleByteBufferAllocator;import org.apache.mina.filter.LoggingFilter;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.filter.codec.textline.TextLineCodecFactory;import org.apache.mina.transport.socket.nio.SocketAcceptor;import org.apache.mina.transport.socket.nio.SocketAcceptorConfig;/** * @author Qixuan.Chen * 创建时间：2015年8月7日 */public class MinaTimeServer {private static final int PORT=9123;public static void main(String[] args) throws IOException { //设置buffer         ByteBuffer.setUseDirectBuffers(false);         ByteBuffer.setAllocator(new SimpleByteBufferAllocator());         //定义acceptor         IoAcceptor acceptor = new SocketAcceptor();         //定义config         SocketAcceptorConfig cfg = new SocketAcceptorConfig();         //设置config,加入filter         cfg.getSessionConfig().setReuseAddress( true );         cfg.getFilterChain().addLast( "logger", new LoggingFilter() );         cfg.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ))));         //加入port handler cfg         acceptor.bind( new InetSocketAddress(PORT), new TimeServerHandler(), cfg);         System.out.println("MINA Time server started."); }}

服务端处理类：

package com.mina.demo;import java.net.InetSocketAddress;import java.util.Date;import org.apache.mina.common.IdleStatus;import org.apache.mina.common.IoHandlerAdapter;import org.apache.mina.common.IoSession;import org.apache.mina.common.TransportType;import org.apache.mina.transport.socket.nio.SocketSessionConfig;/** * @author Qixuan.Chen * 创建时间：2015年8月7日 * 对应的handler ,handler的作用是在对应的网事件的处理代码  */public class TimeServerHandler extends IoHandlerAdapter{public void exceptionCaught(IoSession session, Throwable t) throws Exception {         t.printStackTrace();         session.close();     }     public void messageReceived(IoSession session, Object msg) throws Exception {         String str = msg.toString();         //如果是quit就关闭session退出         if( str.trim().equalsIgnoreCase("quit") ) {             session.close();             return;         }         //否则打印当前日期         //Date date = new Date();         //session.write( date.toString() );        //String clientIP = ((InetSocketAddress)session.getRemoteAddress()).getAddress().getHostAddress();        String clientIP = ((InetSocketAddress)session.getRemoteAddress()).getAddress().getHostAddress();//获取远程客户端的IP        String result = "["+clientIP+"]:"+ str;        session.write(new String(result.getBytes("GBK"),"UTF-8"));        System.out.println("Message written");     }     public void sessionCreated(IoSession session) throws Exception {         System.out.println("Session created");         if( session.getTransportType() == TransportType.SOCKET )             ((SocketSessionConfig) session.getConfig() ).setReceiveBufferSize( 2048 );         session.setIdleTime( IdleStatus.BOTH_IDLE, 10 );    } }

需要导入的依赖：

<!-- mina --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>1.5.8</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-jdk14</artifactId><version>1.6.1</version></dependency><dependency><groupId>org.apache.mina</groupId><artifactId>mina-core</artifactId><version>1.1.7</version></dependency>

测试：

cmd进入doc窗口

先启动服务端

telnet 127.0.0.1 9094
