Problem with composite primary keys in Spring-Data-JPA

[wi21165]

Hello everyone,

I came across an already on other sites discussed problem related to composite primary keys in the spring data jpa extension. (Related Discussion: https://stackoverflow.com/questions/61211391/are-composite-primary-keys-in-jpa-with-quarkus-possible)

As far as I can tell from my research and testing the Quarkus Extension is currently not capable of handling composite primary keys with the @IdClass Annotation of JPA. A neat workaround is just to use the @EmbeddedId Annotation to solve the error.

But this workaround comes to an end when you need to have a @GeneratedValue annotation to creat sequences as part of your primary key. The reason for that is that as shown here https://thorben-janssen.com/composite-primary-keys-sequence/#Mapping_an_EmbeddedId these generators only work with the @IdClass Annotations.

So it seems for me that this feature is either currently not supported, or im missing out on something fundamentally.

Anyways I would be really happy to hear your guys thoughts on this one.

Kind regards :)
