Från stackspåren är det uppenbart att fjäderns jpa konverterar ditt kolumnnamn felaktigt.

I din stack spåra när du försöker köra metoden listaRistoranti(RistoranteRepositoryImpl.java:54) på Entity-klassen Ristorante , jpa konverterar kolumnnamnet som ges som @Column(name = "idRistorante") till kamelfodralet id_ristorante , medan kolumnnamnet i databasen är idRistorante sig själv, vilket orsakar problemet.
Från Configure Hibernate Naming Strategy sektionen av vägledning för åtkomst av vårdata guider :
Försök att använda följande egenskap i application.properties eller application.yml vilket du än använder, så att spring jpa inte konverterar ditt kolumnnamn och använder det som det är specificerat i din Entity.
