Здравствуйте, я создал образец приложения, использующего hibernate с hsqldb.Hibernate не сохраняет записи в базе данных
Когда я запускаю свое приложение, он отлично работает и не дает никаких ошибок, он дает следующее подтверждение для моих таблиц.
Inserting Record
Hibernate: insert into SC_EMPLOYEE.tbl_test (name, id) values (?, ?)
Hibernate: insert into SC_EMPLOYEE.TBL_EMPLOYEE (EMP_NAME, EMP_ADDRESS, EMP_EMAIL, EMP_PHONE, EMP_SALARY, EMP_ID) values (?, ?, ?, ?, ?, ?)
Record inserted successfully..
Но когда я проверяю таблицы, у него нет новых записей.
следующее - код моего приложения.
