使用spring-cloud-config-client时如何配置自定义RestTemplate？

Question

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.
