I din stack spor, mens du forsøger at udføre metoden listaRistoranti(RistoranteRepositoryImpl.java:54) på enhedsklassen Ristorante , jpa konverterer kolonnenavnet givet som @Column(name = "idRistorante") til kamelhuset id_ristorante , mens kolonnenavnet i databasen er idRistorante sig selv, hvilket er årsag til problemet.
Fra Konfigurer Dvale-navnestrategi sektion af forårsdataadgang. vejledninger :
Prøv at bruge følgende egenskab i application.properties eller application.yml hvad end du bruger, så spring jpa ikke konverterer dit kolonnenavn og bruger det, som det er angivet i din enhed.
