Support for ValueObjects/Embedded [DATAJDBC-111]

[spring-projects-issues]

Jens Schauder opened DATAJDBC-111 and commented

If an entity has a reference to a value object (no ID) it should be possible to persist the object in the same table as the entity, with columns matching the properties of the value object plus a prefix configurable via an annotation on the reference to the value object.

    class LegoSet {
        @Id
        Long id;

        @Embed("age_")
        private AgeRange age;
    }

    class AgeRange {
        Duration from;
        Duration to;
    }

should map to a table

LegoSet(id, age_from, age_to)

For single attribute classes, the goal can be achieved by custom conversions. See https://stackoverflow.com/a/53296199/66686
