How to configure a custom RestTemplate when using spring-cloud-config-client?

I am trying to use spring-cloud-config-client to read my configuration properties from a spring-cloud-config-server application on startup. My application is a Spring-Boot application and what I need to do is adding a specific header to the request before it is sent to the config server.

I have read the documentation (http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html) and I can't find any way to customize the ConfigServicePropertySourceLocator with a provided RestTemplate.

What would be the best way to do that?

Many thanks

To expand on @spencergibb answer.

  • Create a configuration class.

    @Configuration
@ConditionalOnClass({ConfigServicePropertySourceLocator.class, RestTemplate.class})
public class ConfigClientBootstrapConfiguration {

    private final ConfigServicePropertySourceLocator locator;

    @Autowired
    public ConfigClientBootstrapConfiguration(ConfigServicePropertySourceLocator locator) {
        this.locator = locator;
    }

    @PostConstruct
    public void init() {
        RestTemplate restTemplate = new RestTemplate();
        locator.setRestTemplate(restTemplate);
    }

}

  • Create a bootstrap.factories in subdirectory resources/META-INF

    # Bootstrap components
org.springframework.cloud.bootstrap.BootstrapConfiguration=\
path.to.config.ConfigClientBootstrapConfiguration

There is a ConfigServicePropertySourceLocator.setRestTemplate(). In you configuration class add a @PostConstruct method where you could set your RestTemplate there.
