How to catch what is POST'ed to rest api

I have a rest api set up at api/books, and one can send a new book object there, and it will be added to the database. The guestion is, how can I correctly catch what is being POST'ed, so one can for example, validate what is being sent?

@RequestMapping(value="/api/books", method = RequestMethod.POST)
public String bookSavePost(@RequestBody Book book) {
    bookRepository.save(book);
    return "redirect:/api/books";
}

This works, as in it saves the book and I can catch what the user sends, but with this enabled, it overrides the default REST method, which doesn't allow one to actually view the api anymore. If I change this particular method to GET, it returns a string "redirect:/api/books", so it doesn't even redirect anything. Is there some way to actually redirect it to the rest api endpoint?

You can write your own reuquest Interceptor .

Spring provides HandlerInterceptor class :

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/servlet/HandlerInterceptor.html

Here is a quick sample how to do this: https://www.baeldung.com/spring-mvc-handlerinterceptor

A redirect requires three two things to be successful: A HTTP code of 301 or 302 AND a location header that includes the endpoint to which you want the client to visit.

E.g., in the headers section you should have

location: '/correct/endpoint'
