apache mina 入门

　　第一步：创建ArenaSessionHandle
　　package com.war.socket.arena;
　　import org.apache.mina.core.service.IoHandlerAdapter;
import org.apache.mina.core.session.IdleStatus;
import org.apache.mina.core.session.IoSession;
import org.json.JSONObject;
　　import com.war.constant.ArenaSocketConstant;
　　
public class ArenaSessionHandle extends IoHandlerAdapter{
　　@Override
 public void sessionCreated(IoSession session) throws Exception {
 }
　　@Override
 public void sessionOpened(IoSession session) throws Exception {
 }
　　@Override
 public void sessionClosed(IoSession session) throws Exception {
  session.close();
  ArenaSocketService.removeArenaBattleSession(session);
 }
　　@Override
 public void exceptionCaught(IoSession session, Throwable cause)
 throws Exception {
  session.close();
  ArenaSocketService.removeArenaBattleSession(session);
 }
　　@Override
 public void messageReceived(IoSession session, Object message)
 throws Exception {
　　// 处理业务逻辑
　　}
　　@Override
 public void messageSent(IoSession session, Object message) throws Exception {
 }
　　@Override
 public void sessionIdle(IoSession session, IdleStatus status)
 throws Exception {
 }
　　
}
　　第二步：创建服务端 ArenaSocketServer
　　package com.war.socket.arena;
　　import java.io.IOException;
import java.net.InetSocketAddress;
import java.nio.charset.Charset;
　　import org.apache.log4j.Logger;
import org.apache.mina.core.service.IoAcceptor;
import org.apache.mina.filter.codec.ProtocolCodecFilter;
import org.apache.mina.filter.codec.textline.TextLineCodecFactory;
import org.apache.mina.transport.socket.nio.NioSocketAcceptor;
　　import com.war.common.ResourceBundleService;
　　public class ArenaSocketServer {
　　private final static int PORT = 12345;
 
 final IoAcceptor acceptor = new NioSocketAcceptor();
 
 private static Logger logger = Logger.getLogger(ArenaSocketServer.class);
 
 public ArenaSocketServer() {
  
  // 注册
  acceptor.setHandler(new ArenaSessionHandle());
  
  // 过滤器
  acceptor.getFilterChain().addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));
　　try {
   // 端口绑定
   acceptor.bind(new InetSocketAddress(PORT));
   System.out.println("Arena Socket Server Started...");
  } catch (IOException e) {
   logger.error(ResourceBundleService.getString("txt.exception"), e);
  }
 }
 
 public void shutdown() {
  acceptor.unbind();
  acceptor.dispose();
 }
}
