我使用Spring MVC 3和Hibernate 4休眠4 + org.hibernate.MappingException：未知實體
下面是代碼來執行DAO操作
@Repository("headCategoryDao")
@Transactional
public class HeadCategoryDaoImpl extends CustomHibernateDaoSupport<HeadCategory, Integer> implements HeadCategoryDao {
@Override
public void delete(HeadCategory headCategory) throws InstanceNotFoundException {
getHibernateTemplate().delete(headCategory);
}
@Override
public HeadCategory findHeadCategoryByName(String headCategoryName) throws InstanceNotFoundException {
List list = getHibernateTemplate().createCriteria("from HeadCategory where headCategoryName="+headCategoryName).list();
if(list.isEmpty()) {
throw new InstanceNotFoundException("HeadCategory not found for provided headCategoryName");
}
return (HeadCategory) list.get(0);
}
@Override
public List<HeadCategory> getHeadCategoriesByMainType(WealthConstants.ACCOUNT_TYPE mainCategoryType) {
List list = getHibernateTemplate().createCriteria("from HeadCategory where mainCategoryType="+ mainCategoryType).list();
return list;
}
}
findHeadCategoryByName方法稱爲拋出異常的下方，什麼可以是問題？
nested exception is org.hibernate.MappingException: Unknown entity: from HeadCategory where headCategoryName=Cash In Hand] with root cause
