我试图在Spring 3.0 ORM中使用JPA 2.0. JPA供应商是Hibernate 3.5.0-Beta-3.

它适用于JPQL,但是当我尝试使用CriteriaQuery时,会发生异常：

java.lang.ClassCastException: $Proxy50
cannot be cast to
javax.persistence.TypedQuery at
$Proxy38.createQuery(Unknown Source)

DAO代码：

@Repository
public class ShopDaoImpl implements
ShopDao {
    @PersistenceContext
    transient EntityManager entityManager;

    @Override
    public Shop findByCrieria() {
        CriteriaBuilder cb = entityManager.getCriteriaBuilder();
        CriteriaQuery
