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
class="org.springframework.beans.factory.config.CustomEditorConfigurer">
<property name="customEditors">
<map>
<entry key="java.net.SocketAddress">
<bean
class="org.apache.mina.integration.spring.InetSocketAddressEditor" />
</entry>
</map>
</property>
</bean>
<!--创建服务器-->
<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)
