Я создал приложение весенней загрузки с postgres подключением к базе данных и сотрудником в качестве имени базы данных, а сотрудников в качестве имени таблицы. Я создал несколько классов контроллера, модели и дао, которые показаны ниже, и все зависимости также добавлены. Но я получаю следующую ошибку при запуске приложения:

Структура проекта
Также вот некоторые предложения, которые я получаю от IDE.
Возникла проблема с добавлением новой записи методом post.
Не можете понять, почему это происходит? Пожалуйста, попробуйте помочь с этим.
