Bumping this, I am having the same issue right after updating Spring Boot 3.4.0 from 3.3.4, and having to upgrade springdoc to 2.7.0. Looking from /actuator/mappings, the swagger endpoint seems unavailable.

Same issue.

Try adding this dependency

org.springdoc
springdoc-openapi-starter-webmvc-ui
2.6.0

i got swagger integrated into it

Same issue with spring boot 3.4.0 and openapi 2.7.0

Try adding this dependency org.springdoc springdoc-openapi-starter-webmvc-ui 2.6.0

i got swagger integrated into it

@hiabhi-cpu

The OP has already shown that they have version 2.7.0 installed, downgrading it to 2.6.0 wouldn't solve the issue since Spring Boot 3.4.0 specifically requires springdoc to be 2.7.0. Let me know if I'm wrong.
