概述
一、概述
Apache Mina Server 是一个网络通信应用框架,也就是说,它主要是对基于TCP/IP、UDP/IP协议栈的通信框架(当然,也可以提供JAVA 对象的序列化服务、虚拟机管道通信服务等),Mina 可以帮助我们快速开发高性能、高扩展性的网络通信应用,Mina 提供了事件驱动、异步(Mina 的异步IO 默认使用的是JAVA NIO 作为底层支持)操作的编程模型。
二、服务器端代码
MinaService.java
[java]
view plain
copy
- package com.czhappy.mina;
- import java.net.InetSocketAddress;
- import java.util.Date;
- import org.apache.mina.core.service.IoAcceptor;
- import org.apache.mina.core.service.IoHandlerAdapter;
- import org.apache.mina.core.session.IdleStatus;
- import org.apache.mina.core.session.IoSession;
- import org.apache.mina.filter.codec.ProtocolCodecFilter;
- import org.apache.mina.filter.codec.serialization.ObjectSerializationCodecFactory;
- import org.apache.mina.filter.logging.LoggingFilter;
- import org.apache.mina.transport.socket.nio.NioSocketAcceptor;
- public class MinaService {
- public static void main(String[] args) {
- IoAcceptor acceptor = new NioSocketAcceptor();
- //添加日志过滤器
- acceptor.getFilterChain().addLast("logger", new LoggingFilter());
- acceptor.getFilterChain().addLast("codec", new ProtocolCodecFilter(new ObjectSerializationCodecFactory()));
- acceptor.setHandler(new DemoServerHandler());
- acceptor.getSessionConfig().setReadBufferSize(2048);
- acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10);
- try {
- acceptor.bind(new InetSocketAddress(9226));
- } catch (Exception e) {
- e.printStackTrace();
- }
- System.out.println("启动服务");
- }
- /**
- * @ClassName: DemoServerHandler
- * @Description: 负责session对象的创建和监听以及消息的创建和接收监听
- * @author chenzheng
- * @date 2016-12-9 下午3:57:11
- */
- private static class DemoServerHandler extends IoHandlerAdapter{
- //服务器与客户端创建连接
- @Override
- public void sessionCreated(IoSession session) throws Exception {
- System.out.println("服务器与客户端创建连接...");
- super.sessionCreated(session);
- }
- @Override
- public void sessionOpened(IoSession session) throws Exception {
- System.out.println("服务器与客户端连接打开...");
- super.sessionOpened(session);
- }
- //消息的接收处理
- @Override
- public void messageReceived(IoSession session, Object message)
- throws Exception {
- // TODO Auto-generated method stub
- super.messageReceived(session, message);
- String str = message.toString();
- Date date = new Date();
- session.write(date.toString());
- System.out.println("接收到的数据:"+str);
- }
- @Override
- public void messageSent(IoSession session, Object message)
- throws Exception {
- // TODO Auto-generated method stub
- super.messageSent(session, message);
- }
- @Override

- }
- }
- }

四、运行结果
1.点击启动服务,观察客户端是否与服务器端连接成功;
2.点击发送消息,观察消息是否发送成功,如果失败判断失败在哪一步。
客户端运行结果:
服务器端运行结果:
