В моем проекте я использую org.neo4j.ogm с весенней загрузкой. Пока я пытаюсь создать отношения, используя @RelationshipEntity, это означает, что они будут созданы успешно. Но он не поддерживает несколько к одному отношению.
Здесь я создаю отношение Blueprint к ScTaxonomy в отношении RELATED_TO_ScTaxonomy. И я хочу добавить свойства отношений для класса catalogueBlueprint.
Я имею в виду, что Blueprint-(RELATED_TO_ScTaxonomy)-ScTaxonomy со значениями класса catalogueBlueprint был сохранен в RELATED_TO_ScTaxonomy.
как только я перезапущу службу, я создам новое соединение, означающее, что уже созданные отношения будут потеряны, и будут сохранены только вновь созданные отношения.
Я использую запрос для
