public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*"); //允许任何域名
        corsConfiguration.addAllowedHeader("*"); //允许任何头
        corsConfiguration.addAllowedMethod("*"); //允许任何方法
        return corsConfiguration;
    }

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