@Bean
public WebClient getWebClientBuilder(){
    return   WebClient.builder().exchangeStrategies(ExchangeStrategies.builder()
            .codecs(configurer -> configurer
                      .defaultCodecs()
                      .maxInMemorySize(16 * 1024 * 1024))
                    .build())
                  .build();
}
