在基于hibernate JPA中实现自定义的分页代码

在hibernate JPA中自定义分页并根据id倒序排序，在接口的实现类中编写如下内容

@PersistenceContext
private EntityManager em;

@Override
public List<Weibo> findAllByLimit(Integer page, Integer size)
{
    CriteriaBuilder criteriaBuilder = em.getCriteriaBuilder();
    CriteriaQuery<Weibo> criteriaQuery = criteriaBuilder.createQuery(Weibo.class);
    Root<Weibo> root = criteriaQuery.from(Weibo.class);
    CriteriaQuery<Weibo> select = criteriaQuery.select(root);
    criteriaQuery.orderBy(criteriaBuilder.desc(root.get("id")));
    TypedQuery<Weibo> typedQuery = em.createQuery(select);
    typedQuery.setFirstResult((page - 1) * size);
    typedQuery.setMaxResults(size);
    return (List<Weibo>) typedQuery.getResultList();
}
