  • RemotingTooMuchRequestException继承了RemotingException；MQClientAPIImpl的sendMessage方法在调用sendMessageAsync或者sendMessageSync方法之前会先判断是否已经超时，如果超时则抛出RemotingTooMuchRequestException(“sendMessage call timeout”)
  • DefaultMQProducerImpl的sendKernelImpl方法在communicationMode为ASYNC或者SYNC时，在执行mQClientFactory.getMQClientAPIImpl().sendMessage之前也会先判断是否超时，超时则抛出RemotingTooMuchRequestException(“sendKernelImpl call timeout”)
  • DefaultMQProducerImpl的sendDefaultImpl方法内部会通过selectOneMessageQueue选择MessageQueue，然后通过sendKernelImpl来执行消息发送，在调用sendKernelImpl方法之前会先判断是否超时，超时的话则设置callTimeout为true，跳出循环，之后抛出RemotingTooMuchRequestException(“sendDefaultImpl call timeout”)；sendSelectImpl方法通过MessageQueueSelector来选择MessageQueue，在通过sendKernelImpl发送消息之前会判断是否超时，超时则抛出RemotingTooMuchRequestException(“sendSelectImpl call timeout”)
