createSyntheticPropertyReference
public static void createSyntheticPropertyReference(AnnotatedJoinColumns joinColumns, PersistentClass targetEntity, PersistentClass associatedEntity, Value value, String propertyName, boolean inverse, MetadataBuildingContext context)
Here we address a fundamental problem: the@JoinColumn
annotation specifies the referenced column in the target table viareferencedColumnName
, but Hibernate needs to know which property or field of the target entity class holds the value of the referenced column at the Java level. (It's going to need the value when it writes the association.)Complicating this hugely is the fact that an association might be based on a composite key with multiple
@JoinColumn
s, and so the referenced columns might even be spread out over multiple fields or properties of the target entity. There's even some extra minor complications resulting from multi-table inheritance and secondary tables.The solution here is:
- if the referenced columns correspond to exactly one property of the target entity, we're good, just use it, or
- otherwise, if a composite key is spread out over multiple
properties, then create a "synthetic"
Component
in the model that aggregates these properties and is considered the target of the association.
Certain limitations arise from the way this solution is currently implemented: for example, if a referenced column belongs to a property of an
@Embeddable
, then every column of that embeddable must occur in the list of referenced columns, and the order of the columns must line up! Some of these limitations could be relaxed by writing a better algorithm for building the syntheticComponent
.
