eclipselink + @convert(json) + postgres + list property

由 折月煮酒 提交于 2019-12-23 11:58:22
问题 I'm using eclipselink 2.6 as a persistence provider of spring data jpa, that in my understanding, now allows you to serialize a subtree of an entity as json using the internal moxy serializer. So I'm trying to mix this to migrate from embedded element collections to a serialized json using the json datatype of postgres. I have an entity named Product, and this entity have the following mapped property: @Convert(Convert.JSON) private List<MetadataIndex> indexes=new ArrayList<MetadataIndex> ();

Jackson mapper with generic class in scala

由 寵の児 提交于 2019-12-23 10:54:55
问题 I am trying to serialise GeneralResponse : case class GeneralResponse[T](succeeded: Boolean, payload: Option[T]) and the payload is GroupsForUserResult : case class GroupsForUserResult(groups: Seq[UUID]).
