Does Spring JPA throw an error if save function is unsuccessful?

Question

I would like to know if and what type of error is thrown by Spring JPA when trying to save an object to a database. The JpaRepository.java says to look at org.springframewor

Answer 1

It should throw a org.springframework.orm.jpa.JpaSystemException. Also, CrudRepostiroy.save returns you a new instance of the entity you gave it, if you get one back, that's a good sign that it saved.
