Override default RestTemplate in Spring Boot 2.1.1

I'm using Spring Boot 2.1.1, Spring Data REST, Spring HATEOAS, Hibernate.

In my @Configuration class I created a custom RestTemplate:

@Configuration @EnableRetry @EnableTransactionManagement @EnableJpaAuditing(auditorAwareRef = "springSecurityAuditorAware") public class CustomConfiguration { @Bean public RestTemplate restTemplate() { RestTemplate restTemplate = new RestTemplateBuilder().setConnectTimeout(httpClientConnectionTimeout) .setReadTimeout(httpClientReadTimeout).build(); ObjectMapper objectMapper = new ObjectMapper(); restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter(objectMapper)); restTemplate.getMessageConverters().add(new StringHttpMessageConverter()); restTemplate.getMessageConverters().add(0, new StringHttpMessageConverter(Charset.forName("UTF-8"))); return restTemplate; } 

I use this restTemplate in a @Component:

@Component public class TenantRestClient { @Autowired private RestTemplate restTemplate; public Tenant register(Tenant tenant) { //my stuff here } 

Until Spring Boot 2.0.3 everything worked fine, but if I update to Spring 2.0.4 or greater, when I try to run my application I've this exception:

I tried to:

1. Set a @Qualifier on restTemplate in my @Configuration class
2. Remove the bean restTemplate in my @Configuration class

The first attempt did't change anything, with the latter I've this weir error:

*************************** APPLICATION FAILED TO START *************************** Description: Field restTemplate in cloud.test.server.rest.clients.TenantRestClient required a bean of type 'org.springframework.web.client.RestTemplate' that could not be found. Action: Consider defining a bean of type 'org.springframework.web.client.RestTemplate' in your configuration. 

Do you have any hint to solve this strange error? And...why does it happen just updating to Spring Boot >=2.0.4 (same code)?
