Adding Core Entities
instead of importing an external xml, why not using the java configuration approach:

    @Bean
    public RestTemplate restTemplate() {
      HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
      factory.setReadTimeout(50000);
      factory.setConnectTimeout(15000);
      RestTemplate restTemplate = new RestTemplate(factory);
      return restTemplate;
    }
