    @Bean
    Client apacheHttpClient(ApacheHttpClientConfigurationProperties properties) {
        CloseableHttpClient apacheClient = HttpClients.custom()
                .setMaxConnTotal(properties.getMaxConnectionsTotal())
                .setMaxConnPerRoute(properties.getMaxConnectionsPerRoute())
                .build();
        return new ApacheHttpClient(apacheClient);
    }
}
