@Transactional(readOnly = false) public void save(BalaTruck balaTruck) { //office.id變更導致hibernate持久化異常。因為一級快取儲存了修改之前的office.id。用clear清除session balaTruckDao.clear(); //儲存時，前端傳入機構id，使用officeDao帶出機構code，再持久化儲存 balaTruck.setTruckOwnCode(officeDao.findOne(balaTruck.getTruckOwnCode().getId())); balaTruckDao.save(balaTruck); }
