Solve the CORS error with Spring Security and a React frontend.

In this video, I solve the CORS error using Spring Security. I use a React frontend to test my application and see when the CORS error is solved. There is a difference when solving the CORS error within the Spring Security instead of the WebMvcConfigurer.

The CORS error appears when a frontend tries to access a backend with a different URL. To solve this problem, I must configure my backend to accept a frontend from a different URL. I can also specify which HTTP methods are accepted and which HTTP Headers.

Thanks. Is there any difference between using this or using WebMvcConfigurer?

Thank you, for your Videos !! Do you have any good sources with clear explanations of WebFlux in Java? I haven't worked with reactive programming before, and now I'm having some trouble understanding how to write good code with WebFlux. I would really appreciate it
