Invalid mapping on handler class OidcWellKnownEndpointController

[王宁]

When the project is updated to version 6.5.x, it cannot be started. The error is "Invalid mapping on handler class OidcWellKnownEndpointController ...". 

It is found that the path wildcard has changed after spring is upgraded to 5.3. The official explanation is "In Spring MVC, the path was previously analyzed by AntPathMatcher, but it was changed to use PathPatternParser introduced in WebFlux from Spring 5.3.0."

I don't know how to submit a legitimate pull request, so I explain the problem here, I hope it can be solved, thank you very much
