Unexpected EntityNotFoundException thrown from JpaRepository

[oliver-b-theissen]

Hi Spring Team,

Environment

1. Spring Boot version 3.5.4
2. Using spring-boot-starter-data-jpa
3. H2 in memory data base

Steps to reproduce

1. Declare a JpaRepository for any entity like public interface AccountRepository implements JpaRepository<Account,Long>
2. Declare AccountRepository accountRepository and let Springframework inject the repository.
3. Call accountRepository.getReferenceById(id) with an non-null id value which is not yet persisted.

Expected

As per Springs @Repository abstraction, a IncorrectResultSizeDataAccessException is thrown.

Actual

JPAs EntityNotFoundException is thrown.

Comments

This breaks the abstraction of Springs @Repository over the underlying persistence layer / data store.

Other methods in JpaRepository convert from JPA specific exceptions into Springs DataAccessException hierarchy. Example: the method save(null) throws InvalidDataAccessApiUsageException. Remark: the Javadoc for save(id) is wrong: it says IllegalArgumentException.

Best,
Oliver

Thank you @oliver-b-theissen. It would be great if you could take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.

Hello @christophstrobl ,
please find attached a minimal example. I wrote several unit tests and you will find my thoughts in the javadoc of the unit tests.
