Java Netty 4.0.30.最终频道写入问题

我已经写了一个编码器，它对我在电线上发送的信息进行编码。在我的处理程序中，我使用了ctx.writeAndFlush（）方法，但似乎没有向远程端点写入任何内容。以下是我的代码片段：

编码器 我不知道我做错了什么。代码挂起在写入线路的一端。请帮忙。这是日志：

FreeSwitchEncoder中的flush在哪里？@Rustam我需要在编码器中执行writeFlush吗？至少你可以试试。你们有其他的处理程序吗？我已经试过了。它仍然挂着。在链中，我有一个入站处理程序。我在调试模式下观察到某种有限循环。

public FreeSwitchMessage sendCommand(ChannelHandlerContext ctx,
                                     final BaseCommand command) {
    ManuelResetEvent manuelResetEvent = new ManuelResetEvent();
    syncLock.lock();
    try {
        manuelResetEvents.add(manuelResetEvent);
        _log.debug("Command sent to freeSwitch [{}]", command.toString());
       ChannelFuture future = ctx.writeAndFlush(command);
        future.addListener(new ChannelFutureListener() {
            public void operationComplete(ChannelFuture future) throws Exception {
                if(!future.isSuccess()){
                    future.cause().printStackTrace();
                }
            }
        });
    } finally {
        syncLock.unlock();
    }

    // Block until the response is available
    return manuelResetEvent.get();
}
