Açıklaması şöyle

- “*” means it will accept any allowable value for that field. For example, allowedMethods will accept GET, POST, PUT, DELETE, OPTIONS, etc. @see org.springframework.http.HttpMethod.

- allowedOrigins, tells Spring to only accept Ajax requests from these URL patterns.

- maxAge — indicates how long to cache the result of a CORS preflight request.
