添加新方法时我丢失了一些东西,但我不知道是什么?它在userDAO.countUsers行中生成找不到符号的编译错误:
@Autowired
private UserDAO userDAO;
@Async
private Future<Long> searchCount(MultiValueMap<String, String> parameters) throws DaoException {
userDAO.countUsers("bla bla");
return new AsyncResult<Long>(Long.getLong("1")); // temp code
}
这是服务接口:
public interface UserDAO {
long countUsers(String bloblo) throws DaoException;
这是实现:
@Service("userDAO")
@SuppressWarnings("unchecked")
@Transactional(readOnly = true, timeout = Constants.TRANSACTION_TIMEOUT, propagation = Propagation.SUPPORTS)
public class UserDaoImpl implements UserDAO {
@PersistenceContext
private EntityManager em;
@Override
public long countUsers(String bloblo) throws DaoException {
// Build request
final QueryCriteria qc = new QueryCriteria(bloblo);
final StringBuilder request = prepareQuery(qc);
request.replace(7, 21, "count(distinct user)");
final Query query = em.createQuery(request.toString());
// Build parameters
addParameters(query, qc);
// Execute
try {
return (Long) query.getSingleResult();
} catch (final RuntimeException e) {
LOG.error(e.getMessage(), e);
throw new DaoException(e);
}
}
帮助真的很感激!
最佳答案
确保您确实从userDAO.countUsers()调用(LanguageCode,UserType,UserRightOrder)导入了类。
也许您应该粘贴错误消息?
