BasicRelationalConverter.writeValue(…) assumes eager entity conversion [DATAJDBC-476]

[spring-projects-issues]

Mark Paluch opened DATAJDBC-476 and commented

Calling writeValue(…) attempts first to write an entity through its identifier. Only if no entity information was found, the write value conversion falls back to simple types.

In other store modules (such as MongoDB), write value conversion attempts a simple value/simple conversion approach first and then falls back to entity conversion.

Eager entity conversion comes with undesired effects such as if a PersistentEntity gets created for a simple type, the conversion treats the simple type as an entity
