排查

1、查看RocketMQ管理端，确认该主题确实存在，但状态有问题

2、经过百度也没有找到真正的原因

3、删除该主题后重新启动服务生产者在该主题发送消息，该主题被重新创建，问题解决

---

原因

未知

---

解决

1、删除主题

2、重新启动服务生产者在该主题发送消息，该主题被重新创建，消息发送正常（本环境的MQ是配置了允许自动创建主题的）

---

补充

同样问题不同的情况

另外一个Java程序也出现同样的问题，但这次删除主题后生产者在该主题发送消息，该主题并没有自动创建

最终解决

1、删除主题

2、服务重启，生产者在该主题发送消息后主题没有自动创建

3、重启mq

4、再次重启服务，生产者在该主题发送消息后主题自动创建
