Ui篇--layout_weight体验(实现按比例显示)

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

    </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: Refreshingorg.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！！！"); 
  }

} 
 }
