Spring Add view rendering support for exception handling with error details

The ResponseEntityExceptionHandler handles exceptions at the MVC/WebFlux level as Problem Details. Right now, only machine-readable formats are managed.

The Spring Boot global error handling not only handles JSON, but also static pages and view templates. This infrastructure is currently based on an ErrorController and an ErrorAttributes object. Errors are handled during error dispatches.

Errors should be as much as possible handled by the application, error dispatches should be the last resort. Spring Framework should help applications by providing a flexible mechanism for rendering errors as HTML. For that, we can probably lean on content negotiation support and the ordering of handlers.

I think this issue could benefit many users. I’d be interested in working on it. Is it okay for a community member to take this on?

Even if the core team decides to handle this, I’d be more than happy to help with the design :)

@YongGoose thanks for the suggestion. I'm not sure how we can implement this, and this issue is currently assigned. So not really a good candidate for community contribution.
