  corsConfiguration.addAllowedOrigin("*");
  corsConfiguration.addAllowedHeader("*");
  corsConfiguration.addAllowedMethod("*");
   corsConfiguration.setAllowCredentials(true);
   return corsConfiguration;
 }

 @Bean
 public CorsFilter corsFilter() {
  UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
  source.registerCorsConfiguration("/**", buildConfig());
  return new CorsFilter(source);
 }
}
