Handling Locale as first part of RequestURI.
Example:
HTTP Request RequestURI
https://foo.bar/{locale}/some/path.html -> /{locale}/some/path.html
https://foo.bar/{locale}/a.html -> /{locale}/a.html
https://foo.bar/{locale}/xyz?a=b -> /{locale}/xyz

builder(Locale defaultLocale) (required)
- Argument
Locale defaultLocale: Defines the default and fallback locale.
supportedLocales(List<Locale> locales)
- Lists all locales that are supported.
defaultRequestURI(String path)
- Defines the path to redirect to if the RequestURI is empty. If not set, the default RequestURI is
/{defaultLocale}.

}A complete, runnable Spring Boot application is available in the
spring-messagesource-xliff-example repository.
It shows this interceptor in action, resolving the locale from the first path segment of the request URI
(e.g. /en/..., /de/...).
