2. Cause analysis

The above error is caused because the monitored Kafka topic does not exist.

3. Solutions

1. Enable Kafka to automatically create topics

2. Manually go to Kafka to create the required topic.

3. The function of Kafka monitoring and checking topic is turned off in the code, as shown in the following code:

spring.kafka.listener.missing-topics-fatal=false
