Should I check if Entity exists before getting/deleting with Spring data JPA?

Question

Spring data jpa has some Exceptions that it throws, like EntityNotFoundException, but they are not descriptive enough and I though it would be good to check if Entity exists, if not - throw an Exception with a nice description. Is that a good decision or is it just a redundant SQL query and it is better to stick stick to Spring data jpa exceptions?

Answer 1

Jpa Repository has been adapted to work with optionals as well. In that case EntityNotFoundException is not thrown.

ex Optional<User> findByName(String name)

So just check if optional isPresent() and that will be enough
