After updating the code, the package succeeds, but an error is reported when the project is started. The error information is shown in the following figure:
I mean, it is obvious that the problem lies in Kafka. After looking at the configuration, it should be the port problem.

Add configuration 127.0.0.1 Kafka-server
Then change the service address of Kafka to kafka-server:9092
in the application configuration file of the project
