Working with embedded keys
As part of the embeddable types introduced in Chapter 7, Types, Converters, and Bindings, we have jOOQ-embedded keys. An embedded key is materialized by the jOOQ Code Generator into the implementation of the jOOQ org.jooq.EmbeddableRecord interface and a handy POJO class. An embedded key extends the default implementation of the org.jooq.EmbeddableRecord interface, which is org.jooq.impl.EmbeddableRecordImpl.
We can define embedded keys for primary and unique keys. Practically, we indicate to jOOQ the primary/unique keys that should become embedded keys, and jOOQ will generate the corresponding artifacts for each primary/unique key, as well as for each foreign key referencing these primary/unique keys. Roughly, embedded keys mirror the primary/unique keys and the corresponding foreign keys in Java classes.
However, in order to employ embedded keys, we need the following configuration:
