springboot 2.5.7 is ok
Comment From: snicoll
This is a springfox problem that should be reported against the relevant project. See also https://github.com/spring-projects/spring-boot/issues/28769
Comment From: wilkinsona
https://github.com/springfox/springfox/issues/3462 is already tracking this on the Springfox side.

Not because springfox ，I have a problem using mqtt
Comment From: wilkinsona
@weir2010 Can you please provide some more context for your comment? I don't see the connection between MQTT and web request path parsing.

Comment From: philwebb
@weir2010 It's still not clear how the sample code you've provided in the comment above relates to the stacktrace that you initially posted. If you believe that this is a Spring Boot issue please provide a sample application that (as a zip file for github project) that reproduces the issue and doesn't have springfox as a dependency.
Comment From: weir2010
I found the problem. It's really swagger ok
Comment From: JuKu
I have the same problem with the newest Spring version 2.6.1 and springfox-swagger2 version 3.0.0 . Is there a workaround?
Comment From: notforward
same problem as mentioned above
Comment From: rcbandit111
Any update? Any plans to release a fixed version?
Comment From: snicoll
Please read the issue history before commenting. This is a springfox issue and nothing we can do here.
Comment From: segomin
https://github.com/springfox/springfox/issues/3462#issuecomment-978707909 helped me btw.
Comment From: mert-unsal
To work around this problem, you can add @EnableWebMvc to spring-context. You are gonna need to disable on testing, @Profile(!test) @EnableWebMvc
This will let you work around the problem.
Comment From: wilkinsona
Thanks for trying to help, @mert-unsal. Unfortunately, that's almost certainly going to have additional unwanted effects as it will disable all of Spring Boot's auto-configuration of Spring MVC.

i resolve with spring boot 2.5.12
Comment From: mercado-dacartech
Yo lo corregí instalando el JAR de mi drive SQL (POSTGRES) directamente a mi proyecto quitandolo del pom y agregarlos al built path y agregandolo al compilado.
