Hello. Nice and informative article. I'm facing a little bit of an issue, I guess because of the spring boot version I'm using. This line 'registry.addViewController("/{x:^(?!api$).*$}/**/{y[\w\-]+}").setViewName("forward:/index.html");)' causes an error:

Error creating bean with name 'viewControllerHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Initialization of bean failed; nested exception is org.springframework.web.util.pattern.PatternParseException: No more pattern data allowed after {*...} or * pattern element Caused by: org.springframework.web.util.pattern.PatternParseException: No more pattern data allowed after {...} or ** pattern element

@pyofori That's true, this approach no longer works in the newest Spring Boot versions. Nowadays I usually write a custom filter in my backend. For example NotFoundIndexFilter. What this filter does is that each time a webpage is requested that is not containing our API-path, it's returning the index-page. The method I use for detecting if a webpage is requested is by checking if the Accept header contains text/html.

I'm updating the tutorial right now with new information because nowadays I also prefer putting the frontend-resources in its own JAR and including that JAR as a dependency in my backend-project.

Thanks a lot. This is very helpful.
