Project to show how to solve the CORS problem for a Spring Boot 3 project.
The project is composed by a backend project made with Spring Boot 3 and Spring Security 6 and a frontend project with React.
The frontend project is just here to show the error.
The backend project uses the configuration in Spring Security to show an alternative to WebMvcConfigurer.
