@LazyToOne deprecated

Hibernate ORM
1

@LazyToOne is deprecated, than what is the alternative to it ?

2

I had this code… but now it shows deprecated … what to do ?

@OneToOne(cascade = CascadeType.ALL, mappedBy = "animal", fetch = FetchType.LAZY)
  @LazyToOne(value = LazyToOneOption.NO_PROXY)
  @ToString.Exclude
  @Valid
  private Giraffe giraffe;

What do you want to express/achieve with this annotation? Chances are, you don’t need this anymore and you can simply remove the annotation.

Okay … When I simply remove this annotation … and retrieve an object of the class in which this girrafe onetoone relation was present (let’s say Main class) … this giraffe object was null in the retrieved entity i think.

Or may be it was loaded somehow but its child objects were null. or not loaded.

Example… I had this test… and It was failing on this line …
assertEquals(1, main.get().getMasterAnimal().getAdditionalInformation().size());

  @Test
  void mainCanBeFetchedByCrn() {

    Main savedmain =
        mainRepository.save(
            mainRepositoryDataProvider.createValidmain());

    entityManager.flush();
    entityManager.clear();

    List<Main> list =
        mainRepository.findByReferenceNumberCrn(crn, mainStatus.DRAFT);
    Optional<Main> main =
        list.stream()
            .filter(
                x ->
                    x.getReferenceNumber() != null
                        && x.getReferenceNumber()
                            .getCrn()
                            .getCrnNumber()
                            .equals(savedmain.getReferenceNumber().getCrn().getCrnNumber()))
            .findAny();

    assertTrue(main.isPresent());
    log.info("fetching master Animal : ");
    assertNotNull(main.get().getMasterAnimal());
    log.info("fetching master Animals additional info : ");
    **assertEquals(1, main.get().getMasterAnimal().getAdditionalInformation().size());**
  }

If you think this is a bug, please create an issue in the issue tracker(https://hibernate.atlassian.net) with a test case(https://github.com/hibernate/hibernate-test-case-templates/blob/master/orm/hibernate-orm-6/src/test/java/org/hibernate/bugs/JPAUnitTestCase.java) that reproduces the issue.

Hello @beikov ,

Thank you for your response, I think the above issue might be related to this one.

https://hibernate.atlassian.net/browse/HHH-17258

Could you please suggest a workaround if the fix is not possible in near future.

Thanks.

As @mbladel answered on JIRA, this will be fixed with the next release, since it is a duplicate of [HHH-17228] - Hibernate JIRA
