Logging Thread ID

여러 개의 서버 인스턴스로 나누어져 있을 때, 통합해서 로그를 보려면 Thread ID가 유용하다. MSA 구조에서는 Span ID, Transaction ID로 엮어서 일련의 연쇄적인 요청 수행의 과정을 볼 수 있지만, MSA 구조가 아니라면 Thread ID로도 충분하다.

RestTemplate vs …

RestTemplate은 스프링에서 기본적으로 지원해주는 HTTP 요청 템플릿이다. 하지만 팀원 중 한 명은 이것이 그렇게 좋지 않다는 의견이다. 오히려 Fiegn Client, Retrofit 같은 것들이 더 깔끔하다고 말한다. 너무 당연하게도 아무 생각없이 RestTemplate을 사용해왔는데, 새로운 시각을 얻게 되었다.
