RestTemplate client misses placeholdered URI's in metrics and logs a pre-build one (with replaced variables)

Created by: unintended

Description

Common practice of using resttemplate is to use methods that handle templated paths with variables either use restTemplate.getUriTemplateHandler().expand() to expand path variables, so resttemplate can store and reuse original template path while logging metrics (e.g. via org.springframework.boot.actuate.metrics.web.client.MetricsClientHttpRequestInterceptor in Spring Boot 2), etc.

I suggest to replace static call in Api client method from:

UriComponentsBuilder.fromPath("/pet/{petId}").buildAndExpand(uriVariables).toUriString()

with one that addresses uriTemplateHandler of restTemplate, eg :

restTemplate.getUriTemplateHandler().expand("/pet/{petId}", uriVariables).toString();
