apache mina ERROR DEAD LOCK: IoFuture.await()
今天用apache mina简单写一个消息服务时在客户端logout时,服务器端报：ERROR DEAD LOCK: IoFuture.await() was invoked from an I/O processor thread. Please use IoFutureListener or configure a proper thread model alternatively.
程序出错在：
public void logout(){
if(session != null && session.isConnected()){
session.close(false).awaitUninterruptibly(20000); //这里抛出上面的异常
//session.close(true);
}
}
服务器代码：
NioSocketAcceptor acceptor = new NioSocketAcceptor();
//增加filter列表
DefaultIoFilterChainBuilderchain = acceptor.getFilterChain();
chain.addLast( "logger", new LoggingFilter() );
chain.addLast("myChin", new ProtocolCodecFilter(new ObjectSerializationCodecFactory()));
//消息处理
acceptor.setHandler(new MessageHandler());
acceptor.bind(new InetSocketAddress(IP, PORT));
网上查找说在单线程模式下不能用future.awaitUninterruptibly()。增加ExecutorFilter就能解决。
chain.addLast("exceutor", new ExecutorFilter());
看来自己对异步
