[SpringBoot] e.getStackTrace() 출력 결과 차이

• log.error("stackTrace={}", e.getStackTrace());

에러내용
stackTrace=kr.co.test.controller.TestController.responseFail2(TestController.java:24)

기존에 getStackTrace하면 이렇게 간단하게만 나온다.

 

• log.error("reason={}, stackTrace={}", e.getCause(), e.getStackTrace());

getCause를 하고 났더니 getStackTrace 내용이 바꼈다.

 

• log.error("stackTrace={}, reason={}", e.getStackTrace(), e.getCause());

그래서 getStackTrace를 먼저 해봤는데 똑같이 stack trace가 보인다.

 

• log.error("reason={}, stackTrace={}", e, e.getStackTrace());

이유는 모르겠지만 위 코드로 원하는 로그(e.printStackTrace()를 출력하고 싶었다.)를 얻었다.
