Answer 1

Adding this piece of code to your class annotated with @EnableZuulProxy should do the trick.

@Bean
public CorsFilter corsFilter() {
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    final CorsConfiguration config = new CorsConfiguration();
    config.setAllowCredentials(true);
    config.addAllowedOrigin("*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("OPTIONS");
    config.addAllowedMethod("HEAD");
    config.addAllowedMethod("GET");
    config.addAllowedMethod("PUT");
    config.addAllowedMethod("POST");
    config.addAllowedMethod("DELETE");
    config.addAllowedMethod("PATCH");
    source.registerCorsConfiguration("/**", config);
    return new CorsFilter(source);
}
