Class WebMvcConfigurerAdapter
is deprecated as of 5.0 WebMvcConfigurer
has default methods and can be implemented directly without the need for this adapter. For this case:
@Configuration
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("http://localhost:3000");
}
}
