内部方法 findLastHistoric(HistoricalIndexRepositoryImpl.java:37)

类(class):

@Repository
public class HistoricalIndexRepositoryImpl implements HistoricalIndexRepository{

    @PersistenceContext 
    private EntityManager em;

    @Override
    public Iterable<HistoricalIndex> findIntraDay(String code, Date of) {
        TypedQuery<HistoricalIndex> sqlQuery = em.createQuery("from HistoricalIndex h where h.index.code = ? and h.fromDate >= ? and h.toDate <= ? ORDER BY h.toDate asc", HistoricalIndex.class);
        sqlQuery.setParameter(1, code);
        sqlQuery.setParameter(2, DateUtil.getStartOfDay(of));
        sqlQuery.setParameter(3, DateUtil.getEndOfDay(of));
        return sqlQuery.getResultList();
    }

    @Override
    public Iterable<HistoricalIndex> findLastIntraDay(String code) {
        return findIntraDay(code, findLastHistoric(code).getToDate());
    }

    @Override
    public HistoricalIndex findLastHistoric(String code){
        TypedQuery<HistoricalIndex> sqlQuery = em.createQuery("from HistoricalIndex h where h.index.code = ? ORDER BY h.toDate desc", HistoricalIndex.class);
        sqlQuery.setParameter(1, code);
        return sqlQuery.setMaxResults(1).getSingleResult();
    }
}

请帮我解决这个错误。如果您需要其他信息，请告诉我。

问候。

这个怎么样？

    TypedQuery<HistoricalIndex> sqlQuery = em.createQuery("from HistoricalIndex h where h.index.code = ?1 ORDER BY h.toDate desc", HistoricalIndex.class);
