Witam mam problem z działaniem aplikacji RESTowej powiązanej z MySQL. Od razu zaznacze, że dopiero się uczę programować i mogę mieć gdzieś jakiś głupi bład.
Aplikacja ma za zadanie zapisać treść strony którą otrzyma metodą POST. Metoda GET ma pobrać wszystkie zapisane strony z tabeli. Kod się kompiluje i wywołanie testowego endpointu /ja działa, ale gdy chcę użyć POST/GET otrzymuje z serwera status 500-GET, 405-POST. Samo zapisanie i wyciągnięcie z bazy działa z pominięciem reszty programu, więc gdzieś jest jakiś błąd między Hibernatem, a resztą aplikacji.
