When no API version is provided, static resources fail to load

[ghoonch4]

I am experimenting with the API Versioning feature introduced in Spring 7.

I have an image file named foo.png under the resources/static directory.
However, when I try to access http://localhost:8080/foo.png in the browser, the image cannot be loaded.

In my case, the HandlerMappings are evaluated in the following order:

1. RouterFunctionMapping (with ApiVersionStrategy)
2. RequestMappingHandlerMapping (with ApiVersionStrategy)
3. WelcomePageHandlerMapping
4. BeanNameUrlHandlerMapping
5. WelcomePageNotAcceptableHandlerMapping
6. SimpleUrlHandlerMapping

I expect the image resource to be handled by SimpleUrlHandlerMapping. However, due to the ordering, the request fails earlier in the initApiVersion(HttpServletRequest) method of RouterFunctionMapping.

While it's not the same symptom, I think this is the same problem: when choosing an API version with a path variable (here, probably the first path segment of the URL path), this shadows all other mappings.

We will have a look at your other issue. Thanks!
