   //DAO CLASS

 @Component
 public class FeedBackDAOImpl implements FeedBackDAO {

@Autowired
private HibernateTemplate ht;

@Transactional(readOnly = false)
@Override
public int insertFeedBack(FeedBack feedBack) {
    int count=0;
    ht.setCheckWriteOperations(false);
    count=(Integer)ht.save(feedBack);
    return count;
}
 }

如何在Springsp中解决此异常？
