I know that this is an old question, but I was looking for the answer to this myself. You need to add a RestTemplate interceptor when configuring the RestTemplate. An example below in annotation configuration:

@Bean
public RestTemplate restTemplate() {

    final RestTemplate restTemplate = new RestTemplate();

    restTemplate.setMessageConverters(Arrays.asList(
            new FormHttpMessageConverter(),
            new StringHttpMessageConverter()
    ));
    restTemplate.getInterceptors().add(new BasicAuthorizationInterceptor("client", "secret"));

    return restTemplate;
}

Javadoc for BasicAuthorizationInterceptor.

I was stuck on this for a good few hours. Maybe it will help somebody out in the near future.
