В моей программе Java .. Hibernate Bean Class определить один столбец, такой как .. < /p>
shrong> timetablevo.java
@Column(name="REPEAT_DAYS")
private WeekdayType repeatDays;//hear WeekdayType is Enum Class
< /code>
И в классе моего обслуживания я использую этот класс TimeTableVo.java Bean As .. < /p>
Это мой класс службы: < /p>
public void createEvent(TimetableVO timetableVO) {
WeekdayType weekday = null;
for (String day : timetableVO.getTemp().split(",")) {
weekday = WeekdayType.valueOf(day);
}
timetableVO.setRepeatDays(weekday);
userDAO.createEvent(timetableVO);
}
< /code>
И мой класс DAO я вставляю объект TimeTableVo .. < /p>
public void createEvent(TimetableVO timetableVO) throws DataAccessException {
entityManager.persist(timetableVO);
}
< /code>
Но исключение придет .. < /p>
