MINA的第一个例子终于能运行了__1

照着网上的例子,一步一步来,但是结果总是不能运行.今天终于成功了.
我分别使用MINA的两个版本做了实验:0.9和1.0.将我实现的过程及遇到的问题分别介绍一下:
运行环境：winXP，eclipse3.2.1，jdk 1.4.2
一、MINA0.9

引用的包：
mina-0.9.0.jar
slf4j-simple.jar

类文件两个：
ReverseEchoServerHandler.java，用来实现IoHandlerAdapter。

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


public class ReverseEchoServerHandler extends IoHandlerAdapter {

	/* (non-Javadoc)
	 * @see org.apache.mina.common.IoHandlerAdapter#exceptionCaught(org.apache.mina.common.IoSession, java.lang.Throwable)
	 */
	public void exceptionCaught(IoSession session, Throwable arg1) throws Exception {
		session.close();
	}

	/* (non-Javadoc)
	 * @see org.apache.mina.common.IoHandlerAdapter#messageReceived(org.apache.mina.common.IoSession, java.lang.Object)
	 */
	public void messageReceived(IoSession session, Object message) throws Exception {
		String m = (String)message;
		StringBuffer buf = new StringBuffer();StringBuilder
		for(int i = m.length() -1;i>=0;i--){
			buf.append(m.charAt(i));
		}
		session.write(buf.toString());
	}
}

ReverseEchoServer.java

import java.nio.charset.Charset;

import org.apache.mina.common.DefaultIoFilterChainBuilder;
import org.apache.mina.common.TransportType;
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.registry.Service;
import org.apache.mina.registry.ServiceRegistry;
import org.apache.mina.registry.SimpleServiceRegistry;

public class ReverseEchoServer {

	public static void main(String[] args) throws Exception{
		ServiceRegistry registry = new SimpleServiceRegistry();
		Service service = new Service("reverse_echo",TransportType.SOCKET,8081);
		DefaultIoFilterChainBuilder chain = new DefaultIoFilterChainBuilder();
		chain.addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));
		
		chain.addLast("logger", new LoggingFilter());
		
		registry.bind(service,new ReverseEchoServerHandler(),	chain);

	}
}

刚开始时仅使用了mina-0.9.0.jar包，结果总是报错，原来mina的log使用了slf4j，所以还需要这个包.
运行ReverseEchoServer。
用PuTTY看一下效果吧。


二、mina1.0
MINA的第一个例子终于能运行了__2
