CORS not being applied - Spring Boot

Question

I have a Spring Boot configuration class to handle CORS. This class theoretically allows all origins, all methods and with all headers.

@Configuration
public class CorsConfiguration implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedMethods("*").allowedOrigins("*").allowedHeaders("*");
    }
}

However, at the front end, I get:

Access to Xmlhttprequest at ːhttp://172.17.178.81:3000/api/v1/token’ from origin ːhttp://172.17. 0.75:8002' has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No Access-Control-Allow-Origin' header is present on the requested Resource.

When I write my endpoint with @Crossorigin, it works normally.

I would like to know what can be done. I don’t believe that annotating every endpoint with @Crossorigin is the right thing to do.

I wrote down the class with @Enablewebmvc and everything seemed to work smoothly.

@Configuration
@EnableWebMvc
public class CorsConfiguration implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedMethods("*").allowedOrigins("*").allowedHeaders("*");
    }
}
