在使用rocketmq的demo发送消息时，一直报如下错误
Exception in thread “main” org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException: sendDefaultImpl call timeout
at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendDefaultImpl(DefaultMQProducerImpl.java:640)

已经加了brokerIP1=127.0.0.1 的配置项，但是就是不行
然后把发送消息的代码加了个超时时间就可以了
SendResult sendResult = producer.send(msg, 100000);
