Class EnumUuidConverters.StringToRef

java.lang.Object
su.onno.spring.EnumUuidConverters.StringToRef
All Implemented Interfaces:
org.springframework.core.convert.converter.GenericConverter
Enclosing class:
EnumUuidConverters
@ReadingConverter public static final class EnumUuidConverters.StringToRef extends Object implements org.springframework.core.convert.converter.GenericConverter
Reads a Ref back from a varchar column that holds the referenced id as text.

The Ref → uuid column is the norm, but a column that pre-existed as varchar (e.g. an attribute retyped from String to Ref<T>) hands the id back as a String. This mirrors EnumUuidConverters.StringToEnum for the reference case so such legacy and migrated columns round-trip instead of throwing.
