Retry AOP

Retry 애노테이션으로 재시도 실행결과가 좀 이상합니다.

Written on

603

본문에는 예외가 발생 시 Retry 애노테이션을 확인해서

request를 재시도 하는것으로 나와있는데

막상 실행 시켜보면 예외가 발생하지 않아도

Retry 프록시가 실행되는거 같아서요

먼가 잘못이해하고 있는걸까요??

실행결과 로그는 아래와 같습니다.

Spring AOP helps effectively handle auxiliary functions (cross-cutting concerns) that repeatedly appear across multiple modules, outside of an application's core business logic. What type of concerns do Logging or Retry fall under?
