> Describe my problem：i want to send message to client for three times, when
> the first time I send to client,but client doesn't answer ,So I try to send
> again,When the second time I send,I can receive the answer ,But my core is
> struck in ReadFuture.awaitUninterruptibly(20, TimeUnit.SECONDS) until
> cancel.That is my code,Thanks to answer.
> {code:java}
> if (future.isWritten()) {
> log.debug("成功发送数据" + protocolMsgVO.toByteString());
> ReadFuture readFuture = session.read();
> BaseProtocolMsgVO msgReceive = null;
> // 等待数据读取完成 等待10s 如果没有返回 关掉连接
> if (readFuture.awaitUninterruptibly(20,
> TimeUnit.SECONDS)) {
> msgReceive = (BaseProtocolMsgVO)
> readFuture.getMessage();
> } else {
> session.getConfig().setUseReadOperation(false);
> // 设置为不需要读取数据
> if(count >= 3){
> log.info("重发超过三次,断开连接");
> // 关掉连接
> session.closeNow();
> throw new BusiException("读取设备响应数据超时");
> }else{
> log.info("重发次数："+count);
>
> session.getConfig().setUseReadOperation(false); // 设置为不需要读取数据
> sendCmd(deviceIp, protocolMsgVO,
> pk_user, openid);
> }
>
> }
> //重置重发次数
> session.setAttribute("count", 0);
> if (readFuture.getException() != null) {
> session.getConfig().setUseReadOperation(false);
> // 设置为不需要读取数据
> // 关掉连接
> session.closeNow();
> throw new

> That's my server log and tcp log
