AbstractOioByteChannel中的无限循环

Question

我不确定AbstractOioByteChannel.doWrite（ChannelOutboundBuffer in）中的无限循环是否正确，netty版本4.0.9 谢谢， -Igor

Answer 1

如果没有消息

，您似乎需要添加循环中断（下面加粗）

    *for (;;) {
        Object msg = in.current();
        **if (msg == null) {
            break;
        }**
        if (msg instanceof ByteBuf) {
            ....
        } else if (msg instanceof FileRegion) {
            ...
        } else {
            in.remove(new UnsupportedOperationException(
                    "unsupported message type: " + StringUtil.simpleClassName(msg)));
        }
    }*
