long answer

I took over a SpringCloud project, and Sentinel has been integrated by default, but later found that the website visits are very small, and the server resources are not enough, so Sentinel needs to be disabled to release memory resources.

Theoretically, I think there should be a switch somewhere, but after searching for an hour, I found the official document (it can be regarded as a document):

https://github.com/alibaba/spring-cloud-alibaba/blob/2.2.x/spring-cloud-alibaba-starters/spring-cloud-starter-alibaba-sentinel/src/main/resources/META-INF/additional-spring-configuration-metadata.json

The first configuration is just that:
