Spring2.5+MINA2搭建Socket Server

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spring-mina-1.xml，配置mina服务：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><!-- mina server --><bean id="serverHandler" class="minaT5.ServerHandler" /><!-- executorFilter多线程处理 --><bean id="executorFilter" class="org.apache.mina.filter.executor.ExecutorFilter" /><bean id="mdcInjectionFilter" class="org.apache.mina.filter.logging.MdcInjectionFilter"><constructor-arg value="remoteAddress" /></bean><bean id="codecFilter" class="org.apache.mina.filter.codec.ProtocolCodecFilter"><constructor-arg><!-- <bean class="org.apache.mina.filter.codec.textline.TextLineCodecFactory" /> --><!-- 处理对象流时候用ObjectSerializationCodecFactory --><!-- <bean class="org.apache.mina.filter.codec.serialization.ObjectSerializationCodecFactory" /> --><bean class="minaT5.ServerCodeFactory" /></constructor-arg></bean><bean id="loggingFilter" class="org.apache.mina.filter.logging.LoggingFilter" /><bean id="filterChainBuilder"class="org.apache.mina.core.filterchain.DefaultIoFilterChainBuilder"><property name="filters"><map><entry key="executor" value-ref="executorFilter" /><entry key="mdcInjectionFilter" value-ref="mdcInjectionFilter" /><entry key="codecFilter" value-ref="codecFilter" /><entry key="loggingFilter" value-ref="loggingFilter" /></map></property></bean><bean class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="java.net.SocketAddress"><bean class="org.apache.mina.integration.beans.InetSocketAddressEditor" /></entry></map></property></bean><bean id="ioAcceptor" class="org.apache.mina.transport.socket.nio.NioSocketAcceptor"init-method="bind" destroy-method="unbind"><property name="defaultLocalAddress" value="127.0.0.1:1235" /><property name="handler" ref="serverHandler" /><property name="filterChainBuilder" ref="filterChainBuilder" /><property name="reuseAddress" value="true" /></bean></beans>

3、ServerHandler实现类

package minaT5;import java.net.InetSocketAddress;import java.util.Collections;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 = Logger.getLogger(ServerHandler.class);private static Set<IoSession> sessions = Collections.synchronizedSet(new HashSet<IoSession>());/** *  */public ServerHandler() {}@Overridepublic void exceptionCaught(IoSession session, Throwable cause) {session.close();// log.debug("session occured exception, so close it.");log.info("session occured exception, so close it."+ cause.getMessage());}@Overridepublic void sessionCreated(IoSession session) {log.info("remote client [" + session.getRemoteAddress().toString()+ "] connected.");session.write("welcome");sessions.add(session);}@Overridepublic void messageReceived(IoSession session, Object message) {String str = message.toString();log.info("Message written " + str);log.info("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);}@Overridepublic void sessionClosed(IoSession session) {log.info("sessionClosed.");sessions.remove(session);}@Overridepublic void sessionIdle(IoSession session, IdleStatus status) {log.info("session idle, so disconnecting......");session.close();log.info("disconnected.");}@Overridepublic void messageSent(IoSession session, Object message){  log.info("messageSent.");          // disconnect an idle client          //session.close();  }@Overridepublic void sessionOpened(IoSession session){ log.info("sessionOpened.");          //   session.getConfig().setIdleTime(IdleStatus.BOTH_IDLE, IDLE);}}

4、过滤器ServerCodeFactory

package minaT5;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("UTF-8"));    }    public ServerCodeFactory(Charset charset) {encoder = new TextLineEncoder(charset, LineDelimiter.UNIX);decoder = new TextLineDecoder(charset, LineDelimiter.AUTO);}@Overridepublic ProtocolDecoder getDecoder(IoSession arg0) throws Exception {return decoder;}@Overridepublic ProtocolEncoder getEncoder(IoSession arg0) throws Exception {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 minaT5;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {public static void main(String[] args) {ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("spring-mina-1.xml");}}

6、客户端测试ClintTest

package minaT5;import java.net.InetSocketAddress;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;public class ClintTest {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("localhost", 1235));        cf.awaitUninterruptibly();        cf.getSession().write("hello,测试！");        //cf.getSession().write("quit");//  //        cf.getSession().close();          cf.getSession().getCloseFuture().awaitUninterruptibly();//  //        connector.dispose();   }}
