Answer 1

I just add

@Order(Ordered.HIGHEST_PRECEDENCE)

in

public class OAuth2SecurityConfig extends WebSecurityConfigurerAdapter {....}

and config the support of spring

@Bean
public CorsConfigurationSource corsConfigurationSource() {
  CorsConfiguration configuration = new CorsConfiguration();
  configuration.setAllowedOrigins(Arrays.asList("*"));
  configuration.setAllowedMethods(Arrays.asList("*"));
  configuration.setAllowedHeaders(Arrays.asList("*"));

  UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
  source.registerCorsConfiguration("/**", configuration);
  return source;
}

Worked for me.
