Java Netty:关闭通道时发生ClosedChannel异常

为什么当我试图关闭频道时，却抛出了ChannelClosedException？ 使用Channel.close（）关闭，异常的堆栈跟踪：

我认为你应该忽略这一点。它只是告诉您，当它试图将剩余字节写入通道时，通道已经关闭。所以没什么好担心的。

我也遇到了同样的问题。有没有办法确保在关闭通道之前将剩余字节写入通道？我有类似于

ch.write（msg）的东西；ch.close（）是。。。利用未来。ch.write（msg）.addListener（ChannelFuture.CLOSE）；CLOSE在ChannelFuture中不存在。很抱歉，它是ChannelFutureListener.CLOSE我的问题似乎是另一个问题，我们在这里讨论：
