Set default content type header of Spring RestTemplate

I\'m currently using an OAuth2RestOperations that extends the Spring RestTemplate and I would like to specify the content type header.

If you're using Spring Boot, you can just

@Configuration
    public class RestConfig {
        @Bean
        public RestTemplate getRestTemplate() {
            RestTemplate restTemplate = new RestTemplate();
            restTemplate.setInterceptors(Collections.singletonList(new HttpHeaderInterceptor("Accept",
                    MediaType.APPLICATION_JSON.toString())));
            return restTemplate;
        }
    }
