[Kotlin] 외부 REST API를 간편하게 호출 할 수 있는 Feign Client 사용법

 

 

 

하지만 벌크 작업을 하다보니 많은 양의 데이터가 오가고, 의도치 않은 timeout이 발생했다.

이럴 땐 application.yml에 config 설정을 해주면 된다.

feign:
  client:
    config:
      default:
        connectTimeout: 60000
        readTimeout: 60000
        loggerLevel: FULL

• connectionTimeout : 서버에 연결을 시도하는 것에 대한 시간 제한
• readTimeout : 요청한 서버가 로직을 수행하는 것에 대한 시간 제한
• loggerLevel
  • NONE : 로그를 남기지 않음
  • BASIC : Request Method, URL, 응답 코드와 실행 시간을 남김
  • HEADERS : BASIC 정보를 포함 요청, 응답의 헤더를 남김
  • FULL : 요청, 응답의 헤더, 바디, metadata를 남김

 

여기서 특정 페인 클라이언트에만 적용하고 싶을 땐

default 대신 특정 페인 클라이언트 이름을 써주면 된다.

feign:
  client:
    config:
      powerdns-service:
        connectTimeout: 60000
        readTimeout: 60000
        loggerLevel: FULL
