I'm having trouble saving a table previously saved in the transaction. We save TablasMaestra first and then save DatosMaestro by setting up the TablasMaestra and Area. The error is in cargaDatosMaestro upload method. The repository we use to save DatosMaestro is JpaRepository. Can anyone help? Thank you. I enclose an implemented code:

DatosMaestro is new entity and is saved is entityManager.persist() method. Persist method is cascaded to TablasMaestra and fails because TablasMaestra is existing entity. Existing entities have to be saved using entityManager.merge().
Spring repository save method implementation:
@Transactional
public <S extends T> S save(S entity) {
if (entityInformation.isNew(entity)) {
em.persist(entity);
return entity;
} else {
return em.merge(entity);
} }
One solution is don't save TablasMaestra before saving DatosMaestro . It will be saved together with DatosMaestro.
Or use @Transactional on cargaDatosMaestro() method
