按官方文档操作无法收发消息，消费端启动后报错在管理端查看消息详情显示No topic route info in name server for the topic，具体可以查看讨论。

官网文档里的使用工具测试收发是消费者和生产者，这两个代码拉到本地可以正常收发，且不需要提前创建主题。使用Producer.java创建的主题，用sdk可以正常收发，但是在管理端和命令行创建的主题无法使用sdk收发消息，报错No topic route info in name server for the topic

我怀疑官网使用sdk收发消息的代码压根就没有测试，或者只能在特定条件下通过测试。写代码这么多年第一次碰到抄文档跑不动hello world的产品。

要改两行代码才能跑起来，要把注释去掉

图片里不是sdk里的，用sdk里的代码发不出去，并且不能没有方法设置namesrv。
