UPD: Springfox is abandoned
Springfox Swagger had always been kinda dirty solution with a lot of unclearness and bugs, but by now (2021 Q4) it hadn’t been updated for more than a year.
The final straw was the fact that Springfox Swagger 3.0 doesn’t work anymore with Spring Boot 2.6.x.
So, if you reading this, please, consider switching over to https://springdoc.org/ instead.
It’s a pretty straightforward conversion and they do a great job of
documenting it. https://springdoc.org/#migrating-from-springfox.
Original answer
I’ve found a working solution for Springfox 3.0.0 here:
springfox:
documentation:
swaggerUi:
baseUrl: /documentation
openApi:
v3:
path: /documentation/v3/api-docs
swagger:
v2:
path: /documentation/v2/api-docs
Configuration above will change base-path for Swagger endpoints to /documentation without any redirects and other crutches.
It is sad that these configurations is missing in the docs tho.
