MINA框架----------android客户端与服务器端

1、相关资源

MINA：http://mina.apache.org/mina-project/quick-start-guide.html

jar包下载：http://download.csdn.net/detail/hulan_baby/8424891

源代码（客户端）：http://download.csdn.net/detail/hulan_baby/8424897

源代码（服务器端）：http://download.csdn.net/detail/hulan_baby/8424903

由于我没有资源分了，所以请各位有分的亲们贡献一点了，十分感谢。

2、工程目录

log4j.properties不需要

3、服务器端核心代码

import java.util.Date;import org.apache.log4j.Logger;import org.apache.mina.common.IdleStatus;import org.apache.mina.common.IoHandlerAdapter;import org.apache.mina.common.IoSession;public class TimeServerHandler extends IoHandlerAdapter {// 继承了7种方法public static Logger logger = Logger.getLogger(TimeServerHandler.class);// 服务器端与客户端创建连接@Overridepublic void sessionCreated(IoSession session) {// 显示客户端的ip和端口System.out.println(session.getRemoteAddress().toString());logger.info("sessionCreated");}// 从端口接受消息，会响应此方法来对消息进行处理@Overridepublic void messageReceived(IoSession session, Object message)throws Exception {String str = message.toString();if (str.trim().equalsIgnoreCase("quit")) {session.close();// 结束会话return;} else if (str.trim().equalsIgnoreCase("hello")) {session.write("how are you !");// session.getAttribute("");// session.setAttribute("");}Date date = new Date();session.write(date.toString());// 返回当前时间的字符串System.out.println("客户端收到的数据：" + message.toString());System.out.println("Message written...");}@Overridepublic void exceptionCaught(IoSession session, Throwable cause)throws Exception {// TODO Auto-generated method stublogger.info("服务器异常");super.exceptionCaught(session, cause);}// 向客服端发送消息后会调用此方法@Overridepublic void messageSent(IoSession session, Object message) throws Exception {// TODO Auto-generated method stubsuper.messageSent(session, message);logger.info("向客户端消息发送成功");}// 关闭与客户端的连接时会调用此方法@Overridepublic void sessionClosed(IoSession session) throws Exception {// TODO Auto-generated method stublogger.info("服务器端关闭与客户端的连接");super.sessionClosed(session);}@Overridepublic void sessionOpened(IoSession session) throws Exception {// TODO Auto-generated method stublogger.info("服务器与客户端连接打开");super.sessionOpened(session);}@Overridepublic void sessionIdle(IoSession session, IdleStatus status)throws Exception {logger.info("服务器进入空闲......");System.out.println("IDLE " + session.getIdleCount(status));}}

测试：

cmd——>telnet 127.0.0.1 9123,运用此方法亦可测试。

此时有可能会有错误，“telnet不是内部或外部命令.......”.

4、客户端（核心代码）

5、结果

先启动服务器端，再启动客户端

服务器端显示：
