@OnetoMamy @JoinColumn don't populate when @Id is manually assigned [DATAJPA-511]

[spring-projects-issues]

Gökhan Öner opened DATAJPA-511 and commented

Hi,

I'm trying to save a unidirectional OneToMay relationed entitiy.

What I discover is, if I use supply manual id, it's not populating the @JoinColumn using Repository.save . But When I inject EntitiyManagerFactory and persist it manually, it works.

Also, if I define a @GeneratedValue for @Id, then Repository.save also works as expected.

I^ve attached the hibernate config, Entitiy Classes and my service that run the save operation. (updateIstekResponse Method)

Note:

As a workaround, I ad a custom save method to implementing repository, which just call entitiyManager.persist, and it also works. Only thing that I can think is that because I'm supplying the id, maybe spring is calling merge instead of persist??

Note:

As a second workaround, I implement the Persistable in my entity and return true on isNew() method, so I now that i'll never update, just insert

If you manually assign IDs you either have to implement Persistable or provide a custom EntityInformation instance on the JpaRepositoryFactory level as we have no way to distinguish between new entities and ones to be updated

Thanks for the info.
After some readings, I also found that and implemented the Persistable
