本文详细介绍了如何使用Spring框架配置Apache Mina来创建一个多端口服务器，包括配置文件、服务器组件、过滤器及客户端测试。重点在于简化服务器部署过程并展示其实现细节。

虽然说 mina已经发布了2.0的版本了。但是1.7还是应用很多。mina通过spring的配置，使用起来就更加的简单了

现在先看mina在spring中的配置：

本次练习中是监听2个端口

applicationContext-mina.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<bean id="ioAcceptor"
  class="org.apache.mina.integration.spring.IoAcceptorFactoryBean">
  <property name="target">
   <bean
    class="org.apache.mina.transport.socket.nio.SocketAcceptor" />
  </property>
  <property name="bindings">
   <list>//这里是个list 里面可以创建多个监听
    <bean
     class="org.apache.mina.integration.spring.Binding">
     <property name="address" value=":8888" />//监听端口：8888
     <property name="handler" ref="SampleHandler" />//SampleHandler:定义服务器的handler
     <property name="serviceConfig">
      <bean
       class="org.apache.mina.transport.socket.nio.SocketAcceptorConfig">
       <property name="filterChainBuilder"//配置filter
        ref="filterChainBuilder" />//指向：filterChainBuilder
       <property name="reuseAddress" value="true" />
      </bean>
     </property>
    </bean>

    <bean
     class="org.apache.mina.integration.spring.Binding">
     <property name="address" value=":9999" />//第二个监听端口：9999
     <property name="handler" ref="bossSampleHandler" />//监听该端口的 handler
     <property name="serviceConfig">
      <bean
       class="org.apache.mina.transport.socket.nio.SocketAcceptorConfig">
       <property name="filterChainBuilder"
        ref="filterChainBuilder" />
       <property name="reuseAddress" value="true" />
      </bean>
     </property>
    </bean>

   </list>
  </property>
</bean>
<bean id="SampleHandler" class="cn.org.handler.HandlerTwo" />

<bean id="bossSampleHandler" class="cn.org.handler.HandlerOne" />

//定义filter
<bean id="filterChainBuilder"
  class="org.apache.mina.integration.spring.DefaultIoFilterChainBuilderFactoryBean">
  <property name="filters">
   <list>
    <bean
     class="org.apache.mina.filter.codec.ProtocolCodecFilter">
     <constructor-arg>
        <bean
       class="org.apache.mina.filter.codec.textline.TextLineCodecFactory" /> //这个是编码格式filter
     </constructor-arg>
    </bean>
    <bean class="org.apache.mina.filter.LoggingFilter" />//日志的filter
   </list>
  </property>
</bean>
</beans>

sprng的简单配置文件就是这样：

然后看 handler：

SampleHandler 和 bossSampleHandler 。我写的都是一样的：

package cn.org.handler;

import org.apache.mina.common.IdleStatus;
import org.apache.mina.common.IoHandlerAdapter;
import org.apache.mina.common.IoSession;

public class HandlerOne extends IoHandlerAdapter {

public HandlerOne() {
// TODO Auto-generated constructor stub
}

@Override
public void exceptionCaught(IoSession session, Throwable cause)
throws Exception {

}

@Override
public void messageReceived(IoSession session, Object message)
   throws Exception {
  // TODO Auto-generated method stub
  System.out.println("收到信息");
  System.out.println("message :"+message.toString());
}

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

@Override
public void sessionClosed(IoSession session) throws Exception {
// TODO Auto-generated method stub
super.sessionClosed(session);
}

@Override
public void sessionCreated(IoSession session) throws Exception {
System.out.println(session.getRemoteAddress().toString() +"---create");

}

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

@Override
public void sessionOpened(IoSession session) throws Exception {
System.out.println("连接打开："+session.getLocalAddress());
}

}

现在测试：

Test.java

public class Test {

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

}

控制台打印出：

2010-1-16 19:00:51 org.springframework.context.support.AbstractApplicationContext prepareRefresh
信息: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@4b4333: display name [org.springframework.context.support.ClassPathXmlApplicationContext@4b4333]; startup date [Sat Jan 16 19:00:51 CST 2010]; root of context hierarchy

表明服务器就已经启动了：

现在你可以用telent的方式测试。也可以写个客户端的测试类：

写了个客户端的测试类：Clint.java

public class Clint {

/**
* @param args
*/

final static char end = 0x1a;

public static void main(String[] args) {
    SocketConnector connector = new SocketConnector();
  SocketAddress address = new InetSocketAddress("127.0.0.1", 8888);
  SocketConnectorConfig config = new SocketConnectorConfig();
  config.setConnectTimeout(10);// 秒
  connector.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "GB2312" )))); //设置编码过滤器

  connector.getFilterChain().addLast( "logger", new org.apache.mina.filter.LoggingFilter() );

  IoSession session =null;
  ConnectFuture cf = connector.connect(address, new ClintHandler(),
    config);
  cf.join();
  if (cf.isConnected()) {
   session = cf.getSession();
   System.out.println("连接成功");
   session.write("abc");
  }else{
   System.out.println("连接失败！！！");
  }

}
}

这这个测试类中。我只连接了端口：8888 。也可以测试连接端口：9999。看下是什么情况

主要是jar包：spring.jar和mina1.7里面的jar包。还有下载slf4j-nop-1.5.2.jar(这个包是日志相关的)
