Question

HI I have a PK that consists of an embeddable object.

It’s made out of two constraints

@ManyToOne
SpecificType1 spec;
@ManyToOne
SpecificType1 spec;

So basically a mapping table between two objects.

I’d like to cascade delete based on the object that implements this embeddable PK.

I added @Cascade({CascadeType.DELETE, CascadeType.DELETE_ORPHAN}) on SpecificType1, but it just won’t execute the cascade.

Answer 1

This cascade does not make sense.

You have many Foo entities having the same SpecificType1 (ManyToOne). And you’re configuring Hibernate so that if you delete one of the Foo instances, it also deletes the SpecificType1. This would obviously leave all the other Foo entities with an association to an unexisting SpecificType1, which would break the foreign key constraint, and cause a rollback.
