初识mina框架
step1：创建java工程，导入jar包
step2:在src下配置log4j.properties文件
1 log4j.rootLogger=DEBUG,MINA,file 2 log4j.appender.MINA=org.apache.log4j.ConsoleAppender 3 log4j.appender.MINA.layout=org.apache.log4j.PatternLayout 4 log4j.appender.MINA.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss,SSS}%-5p%c{1}%x-%m%n 5 log4j.appender.file=org.apache.log4j.RollingFileAppender 6 log4j.appender.file.File=./log/minademos.log 7 log4j.appender.file.MaxFileSize=5120KB 8 log4j.appender.file.MaxBackupIndex=10 9 log4j.appender.file.layout=org.apache.log4j.PatternLayout 10 log4j.appender.file.layout.ConversionPattern=[VAMS][%d]%p|%m|[%t]%C.%M(%L)%n
step3:服务器端代码
1 package com.per.mina.server; 2 3 import java.net.InetSocketAddress; 4 import java.nio.charset.Charset; 5 6 import org.apache.log4j.Logger; 7 import org.apache.mina.core.service.IoAcceptor; 8 import org.apache.mina.core.session.IdleStatus; 9 import org.apache.mina.filter.codec.ProtocolCodecFilter; 10 import org.apache.mina.filter.codec.textline.LineDelimiter; 11 import org.apache.mina.filter.codec.textline.TextLineCodecFactory; 12 import org.apache.mina.transport.socket.nio.NioSocketAcceptor; 13 14 import com.per.mina.server.handler.Demo1ServerHandler; 15 16 public class Demo1Server { 17 private static Logger logger=Logger.getLogger(Demo1Server.class); 18 private static int port=3005; 19 public static void main(String[] args) { 20 IoAcceptor acceptor=null;//创建连接 21 try { 22 acceptor=new NioSocketAcceptor();//创建一个非阻塞的serverdaunt的Socket 23 //添加消息过滤器 24 acceptor.getFilterChain().addLast("codec", 25 new ProtocolCodecFilter( 26 new TextLineCodecFactory(Charset.forName("utf-8"), 27 LineDelimiter.WINDOWS.getValue(), 28 LineDelimiter.WINDOWS.getValue()))); 29 //设置读取数据的缓冲区大小 30 acceptor.getSessionConfig().setReadBufferSize(2048); 31 //读写通道10 秒内无操作进入空闲状态 32 acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10); 33 //绑定逻辑处理器 34 acceptor.setHandler(new Demo1ServerHandler());//添加业务处理 35 36 //绑定端口 37 acceptor.bind(new InetSocketAddress(port)); 38 logger.info("服务器端启动成功... 端口号为："+port); 39 } catch (Exception e) { 40 logger.error("服务器端启动异常...", e); 41 e.printStackTrace(); 42 } 43 44 } 45 }
1 package com.per.mina.server.handler; 2 3 import java.util.Date; 4 5 import org.apache.log4j.Logger; 6 import org.apache.mina.core.service.IoHandlerAdapter; 7 import org.apache.mina.core.session.IdleStatus; 8 import org.apache.mina.core.session.IoSession; 9 10 public class Demo1ServerHandler extends IoHandlerAdapter { 11 private static Logger logger=Logger.getLogger(Demo1ServerHandler.class); 12 13 @Override 14 public void sessionCreated(IoSession session) throws Exception { 15 logger.info("服务器端与客户端创建连接"); 16 } 17 @Override 18 public void sessionOpened(IoSession session) throws Exception { 19 logger.info("服务端与客户端连接打开"); 20 } 21 @Override 22 public void messageReceived(IoSession session, Object message) 23 throws Exception { 24 String msg=message.toString(); 25 logger.info("服务端接收到的数据为："+msg); 26 if("bye".equals(msg)){ 27 session.close(); 28 } 29 Date date=new Date(); 30 session.write(date); 31 } 32 @Override 33 public void messageSent(IoSession session, Object message) throws Exception { 34 //session.closeNow();//控制长连接与短连接 35 logger.info("服务端发送信息成功..."); 36 } 37 @Override 38 public void sessionClosed(IoSession session) throws Exception { 39 super.sessionClosed(session); 40 } 41 @Override 42 public void sessionIdle(IoSession session, IdleStatus status) 43 throws Exception { 44 logger.info("服务端进入空闲状态..."); 45 } 46 @Override 47 public void exceptionCaught(IoSession session, Throwable cause) 48 throws Exception { 49 logger.error("服务端发送异常", cause); 50 } 51 52 }
step4:客户端代码
1 package com.per.mina.client; 2 3 import java.net.InetSocketAddress; 4 import java.nio.charset.Charset; 5 6 7 8 import org.apache.mina.core.future.ConnectFuture; 9 import org.apache.mina.core.service.IoConnector; 10 import org.apache.mina.core.session.IoSession; 11 import org.apache.mina.filter.codec.ProtocolCodecFilter; 12 import org.apache.mina.filter.codec.textline.LineDelimiter; 13 import org.apache.mina.filter.codec.textline.TextLineCodecFactory; 14 import org.apache.mina.transport.socket.nio.NioSocketConnector; 15 import org.slf4j.Logger; 16 import org.slf4j.LoggerFactory; 17 18 import com.per.mina.client.handler.MinaClientDemo1Handler; 19 20 public class MinaClientDemo1 { 21 //private static Logger logger=Logger.getLogger(MinaClientDemo1.class); 22 private static Logger logger=LoggerFactory.getLogger(MinaClientDemo1.class); 23 private static String HOST="127.0.0.1"; 24 private static int PORT=3005; 25 public static void main(String[] args) { 26 //创建一个非阻塞的客户端程序 27 IoConnector connector=new NioSocketConnector();//创建连接 28 29 //设置连接超时时间 30 connector.setConnectTimeoutMillis(30000); 31 //添加过滤器 32 connector.getFilterChain().addLast("codec", 33 new ProtocolCodecFilter(new TextLineCodecFactory( 34 Charset.forName("utf-8"), 35 LineDelimiter.WINDOWS.getValue(), 36 LineDelimiter.WINDOWS.getValue()))); 37 //添加业务逻辑处理器类 38 connector.setHandler(new MinaClientDemo1Handler());//添加业务处理 39 IoSession session=null; 40 try { 41 ConnectFuture future=connector.connect(new InetSocketAddress(HOST, PORT));//创建连接 42 future.awaitUninterruptibly();//等待连接完成 43 session=future.getSession();//获得session 44 session.write("test mina");//发送消息 45 46 47 } catch (Exception e) { 48 logger.error("客户端连接异常...", e); 49 } 50 session.getCloseFuture().awaitUninterruptibly();//等待连接断开 51 connector.dispose(); 52 } 53 }
package com.per.mina.client.handler; import org.apache.log4j.Logger; import org.apache.mina.core.service.IoHandlerAdapter; import org.apache.mina.core.session.IoSession; public class MinaClientDemo1Handler extends IoHandlerAdapter{ private static Logger logger=Logger.getLogger(MinaClientDemo1Handler.class); @Override public void messageReceived(IoSession session, Object message) throws Exception { String msg=message.toString(); logger.info("客户端接收到的信息为："+msg); } @Override public void exceptionCaught(IoSession session, Throwable cause) throws Exception { logger.error("客户端发生异常",cause); } }
step5：进行测试，先运行服务端，再运行客户端
