使用RocketMQ发送消息抛出异常，异常如下：

org.apache.rocketmq.client.exception.MQClientException: No route info of this topic, TopicTest
    See http://rocketmq.apache.org/docs/faq/ for further details.

　原因：

`Broker` 禁止自动创建`Topic`，且用户没有通过手动创建此`Topic`，或者`broker` 和 `Nameserver`网络不通；

解决方案：

1. 修改broker.properties配置，自动创建topic，添加如下：

autoCreateTopicEnable=true

2. 升级RocketMQ版本为`4.4.0`，新版本会默认自动创建

<dependency>
        <groupId>org.apache.rocketmq</groupId>
        <artifactId>rocketmq-client</artifactId>
        <version>4.4.0</version>
    </dependency>
