checked exception이 발생했을 경우, roll-back 하지 않는다.
기본적으로 checked Exception 은 복구가 가능하다는 메커니즘을 가지고 있기 때문이다.

그렇다면, checked exception의 경우, 개발자가 해당 exception을 복구할 수 있게 구현해줘야 한다.
하지만, 복구할 수 있는 경우는 많지 않다.
RuntimeException을 발생시키고 어떤 예외가 발생해서 Exception이 발생했는지 정보를 전달해주는 것이 현실적이다.

  • Checked Exception을 만나면 복구 전략이 있으면, try catch로 잡아 복구를 진행한다.
  • 복구할 수 있는 경우가 아니라면, 더 구체적인 Unchecked Exception을 발생시켜 정확한 정보를 전달해줘야 한다.
