How to access the current Netty Channel

Question

I would like to use the Netty Channel.attr() to store the HttpRequest for use in library routines.

Anyone know how to find the current channel while in a controller method?

I thought @Threadlocal scope might help, but I can't figure it out (yet).

All Netty handlers have ChannelHandlerContext ctx parameter in method you have to override. For example, SimpleChannelInboundHandler:

@Override
protected void channelRead0(ChannelHandlerContext ctx, Object message) {
    Channel channel = ctx.channel();
}
