Is there a dedicated starter in Spring Boot that implements CORS support?

Spring Boot does not have a dedicated starter specifically for supporting CORS. Instead, CORS support is implemented through standard Spring Framework mechanisms, such as using the @CrossOrigin annotation on controllers or global configuration via WebMvcConfigurer.

Example of global CORS configuration in Spring Boot:

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("https://example.com")
                .allowedMethods("GET", "POST", "PUT", "DELETE");
    }
}

Thus, supporting CORS does not require a separate starter, but uses the built-in functionality of Spring MVC.
