Question

java.io.IOException: 远程主机强迫关闭了一个现有的连接。如何解决

public void exceptionCaught(ChannelHandlerContext ctx, ExceptionEvent e)
throws Exception {
e.getCause().printStackTrace();
Channel channel = e.getChannel();
channel.close();
if (channelGroup.contains(channel)) {
System.out.println("一个客户端退出："+channel.getId());
channelGroup.remove(channel);
}
}
用netty做聊天室，走到e.getCause().printStackTrace()的时候就报错了，请问怎么解决

Answer 1

private static final Logger logger=Logger.getLogger(xxxxx.class.getName());
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
logger.log(
Level.WARNING,
"Unexpected exception from downstream.", cause);
ctx.close();
}
