@ExceptionHandler와 @ControllerAdvice

ExceptionHandler

• what
  @ExceptionHandler 뒤에 작성한 예외가 발생했을 때, 그 예외를 잡아서 하나의 메서드에서 처리할 수 있게 해주는 어노테이션.
• when
  예외를 처리할 때, 각 예외가 발생하는 시점에서 try-catch로 처리하거나 밖으로 throw해서 처리해야한다. 이렇게 하는 경우, 중복되는 코드도 많아지고 관리해야하는 포인트도 많아지게 된다. 따라서 @ExceptionHandler 어노테이션을 이용해 특정 예외에 대한 처리를 공통으로 처리할 수 있도록 책임을 넘겨주고 싶을 때 사용한다.
• why

1. 특정 예외에 대한 처리를 한 곳에서 담당하도록 할 수 있다.

AWS Step functions

InputPath, OutputPath, ResultPath

• InputPath -> the part of the original JSON payload to take to the step
• OutPutPath -> the part of the original JSON payload to return after the step is completed
• ResultPath -> here you can define a node to store the output you create in the step.

Please note "output" node is visible in the step function logs and here in the doc, but you do not have it in the function input. It means { "output": "1.05" } will be just
