1.mina服务初体验-->.<简单的搭建个mina

1.准备jar,,直接去官网

http://mina.apache.org/downloads-mina.html

所需jar包如图:

 

2.服务端程序

log4j.properties配置:

log4j.rootLogger=DEBUG,MINA,file
log4j.appender.MINA=org.apache.log4j.ConsoleAppender
log4j.appender.MINA.layout=org.apache.log4j.PatternLayout
log4j.appender.MINA.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss,SSS} %-5p %c{1} %x - %m%n
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logs/minademos.log
log4j.appender.file.MaxFileSize=5120KB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[VAMS][%d] %p | %m | [%t] %C.%M(%L)%n

package com.ds.mina.server;import java.io.IOException;import java.net.InetSocketAddress;import java.nio.charset.Charset;import org.apache.mina.core.session.IdleStatus;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.filter.codec.textline.LineDelimiter;import org.apache.mina.filter.codec.textline.TextLineCodecFactory;import org.apache.mina.transport.socket.nio.NioSocketAcceptor;import org.slf4j.Logger;import org.slf4j.LoggerFactory;public class MinaServer {private static final Logger log =  LoggerFactory.getLogger(MinaServer.class);private static final int PORT = 9999;public static void main(String[] args) throws Exception {// 创建一个非阻塞的server端的socketNioSocketAcceptor acceptor = new NioSocketAcceptor();// 设置过滤器(使用mina提供的文本换行符编解码器)acceptor.getFilterChain().//addLast("codec", new ProtocolCodecFilter(//new TextLineCodecFactory(//Charset.forName("UTF-8"), LineDelimiter.WINDOWS.getValue(), LineDelimiter.WINDOWS.getValue())));//设置读取数据的缓冲区大小acceptor.getSessionConfig().setReadBufferSize(2048);//读写通道10秒内无操作进入空闲状态acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10);//编写逻辑处理器acceptor.setHandler(new MinaServerHandler());//绑定端口acceptor.bind(new InetSocketAddress(PORT));log.info("mina 服务器启动 ... 端口号为 : " + PORT);}}

服务端的逻辑处理

package com.ds.mina.server;import java.util.Date;import org.apache.mina.core.service.IoHandlerAdapter;import org.apache.mina.core.session.IdleStatus;import org.apache.mina.core.session.IoSession;import org.slf4j.Logger;import org.slf4j.LoggerFactory;public class MinaServerHandler extends IoHandlerAdapter {private static Logger log = LoggerFactory.getLogger(MinaServerHandler.class);@Overridepublic void sessionCreated(IoSession session) throws Exception {log.info("服务端与客户端创建连接...");}@Overridepublic void sessionOpened(IoSession session) throws Exception {log.info("服务端与客户端连接打开...");}@Overridepublic void sessionClosed(IoSession session) throws Exception {}@Overridepublic void sessionIdle(IoSession session, IdleStatus status) throws Exception {log.info("服务端进入空闲状态...");}@Overridepublic void exceptionCaught(IoSession session, Throwable cause) throws Exception {log.info("服务端发生异常...", cause);}/** * 自定义的业务逻辑处理器继承了IoHandlerAdapter类，它默认覆盖了父类的7个方法，<br> * 其实我们最关心最常用的只有一个方法：<br> * messageReceived() ---- 服务端接收到一个消息后进行业务处理的方法；看代码 */@Overridepublic void messageReceived(IoSession session, Object message) throws Exception {String msg = message + "";log.info("服务端收到的数据为 : " + msg);// 服务器接收断开连接指令-->根据这个可以自定义定制一套cmdif ("bye".equalsIgnoreCase(msg)) {log.info("服务器接收连接断开...");session.close(true);}Date d = new Date();session.write(d);}@Overridepublic void messageSent(IoSession session, Object message) throws Exception {// 发送成功后主动断开与客户端的连接session.close(true);log.info("服务端信息发送成功...");}@Overridepublic void inputClosed(IoSession session) throws Exception {}}

3.先用cmd ,,telnet 测试一下

4.客户端编写

MinaClient;

package com.ds.mina.first.client;import java.net.InetSocketAddress;import java.nio.charset.Charset;import org.apache.mina.core.future.ConnectFuture;import org.apache.mina.core.session.IoSession;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.filter.codec.textline.LineDelimiter;import org.apache.mina.filter.codec.textline.TextLineCodecFactory;import org.apache.mina.transport.socket.nio.NioSocketConnector;import org.slf4j.Logger;import org.slf4j.LoggerFactory;public class MinaClient {private static Logger log = LoggerFactory.getLogger(MinaClient.class);private static final int PORT = 9999;private static final String HOST = "127.0.0.1";public static void main(String[] args) {// 创建一个非阻塞客户端程序NioSocketConnector connector = new NioSocketConnector();// 设置连接超时时间connector.setConnectTimeoutMillis(10 * 60 * 1000);// 添加过滤器connector.getFilterChain()//.addLast("codec", new ProtocolCodecFilter(//new TextLineCodecFactory(//Charset.forName("UTF-8"), LineDelimiter.WINDOWS.getValue(), LineDelimiter.WINDOWS.getValue())));//添加业务处理逻辑connector.setHandler(new MinaClientHandler());//创建连接ConnectFuture conn = connector.connect(new InetSocketAddress(HOST, PORT));//等待连接完成conn.awaitUninterruptibly();IoSession session = conn.getSession();//获得sessionsession.write("伟少 like mina ");//发送消息}}

逻辑处理类

package com.ds.mina.first.client;import org.apache.mina.core.service.IoHandlerAdapter;import org.apache.mina.core.session.IdleStatus;import org.apache.mina.core.session.IoSession;import org.slf4j.Logger;import org.slf4j.LoggerFactory;public class MinaClientHandler extends IoHandlerAdapter {private static Logger log = LoggerFactory.getLogger(MinaClientHandler.class);@Overridepublic void sessionCreated(IoSession session) throws Exception {log.info("客户端连接session创建...");}@Overridepublic void sessionOpened(IoSession session) throws Exception {log.info("客户端连接session打开...");}@Overridepublic void sessionClosed(IoSession session) throws Exception {log.info("客户端连接session关闭...");}@Overridepublic void sessionIdle(IoSession session, IdleStatus status) throws Exception {log.info("客户端连接session空闲...");}@Overridepublic void exceptionCaught(IoSession session, Throwable cause) throws Exception {log.error("客户端发生异常 : ", cause);}@Overridepublic void messageReceived(IoSession session, Object message) throws Exception {String msg = message + "";log.info("客户端接收到信息为 : " + msg);}@Overridepublic void messageSent(IoSession session, Object message) throws Exception {}@Overridepublic void inputClosed(IoSession session) throws Exception {}}

想下载可执行的项目,,可到下面链接,,已提交到github上,后面会陆续发表,我也在学习这方面的..

自己复写一边,理解里面的东西.
