Spring Boot Restful Service and CORS problem

I created a Restful service with Spring Boot and I am sending HTTP requests to this service with Angular. I was getting a CORS error when I sent a request with Angular and I used artificial intelligence to solve the error. In the first attempt, it asked me to suggested the following bean.

@Bean
public WebMvcConfigurer corsConfigurer(){
return new WebMvcConfigurer() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("http://localhost:4200")
.allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD", "OPTIONS")
.allowedHeaders("*")
.allowCredentials(true);
}
};
}


Then, when I wanted to export the front-end as live server, I also got CORS error and it suggested me to add the following bean.

@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration config = new CorsConfiguration();
config.addAllowedOrigin("http://192.168.5.76:4200");
config.addAllowedOrigin("http://localhost:4200");
config.addAllowedMethod("*");
config.addAllowedHeader("*");
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}


When I did some more research on the internet, I saw that the WebMvcConfigurer structure is recommended. But I don't understand which one I should use in which situation and I couldn't find a detailed explanation. I wonder if there is someone who can provide an explanatory source or explanation on this subject.
