I've created a @MapIdToNewUUIDv7 annotation:

import org.mapstruct.Mapping

@Retention(AnnotationRetention.SOURCE)
@Mapping(target = "id", expression = "java(com.github.f4b6a3.uuid.UuidCreator.getTimeOrderedEpochPlus1())")
annotation class MapIdToNewUUIDv7

That's nice and reusable since no other information is needed. But I'm also trying to map this:

@Mapping(target = "tsid", expression = "java(TsidFactory.generateForClass(HouseEntity.class))")
and it would be great if I could create either

• another mapper which understands how to get the class to pass in HouseEntity here, or
• a custom annotation that would just accept it, like @MapTsidFor(HouseEntity::class)
