我使用Netty-5.0.0.Alpha1.I想要使用 ChannelFutureListener.CLOSE 来关闭连接，但它不起作用。 我将IdleStateHandler添加到管道 .addLast（new IdleStateHandler（45,0,0，TimeUnit.SECONDS））
@Override
public void userEventTriggered(ChannelHandlerContext ctx, Object evt) throws Exception {
if (evt instanceof IdleStateEvent) {
log.warn("closeing idle connection：{}", ctx.channel().attr("MAC_ADDRESS").get());
//write an empty message to the client then close the channel
ctx.writeAndFlush(Unpooled.EMPTY_BUFFER).addListener(ChannelFutureListener.CLOSE);
}
}
@Override
public void channelInactive(ChannelHandlerContext ctx) throws Exception {
log.warn("channel closed");
}
服务器每45秒触发一次IdleStateEvent，但从不调用channelInactive方法。

但它在大多数时候运作良好，这种情况只发生过一次。
