[jhg]

No, ningun error, es más, si no es porque miro las tablas de la base de datos a saber loq ue hubiera tardado en darme cuenta del error. Las estidades del rol y del usuario son las siguientes:

Al principio añadia el rol antes del persist y el flush, pense seria por el id de usuario y lo puse despues, y como seguia fallando pense en buscar el usuario despues de guardarlo y añadir el rol, pero falla todo, creo el problema este al añadir el rol pero no tengo ni idea.
