JPA ERROR: Invalid operation for forward only resultset : absolute

Question

我正在尝试使用 Criteria JPA:

获取行

我的关系是：

class Photo { 
  ...

  @ManyToOne(fetch = FetchType.EAGER)
  @JoinColumn(name = "GALLERY_ID", referencedColumnName = "ID")
  private Gallery gallery;

  ...
}

我的 DAO 是：

CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Photo> criteriaQuery = builder.createQuery(Photo.class);
Root<Photo> root = criteriaQuery.from(Photo.class);

List<Predicate> predicateList = new ArrayList<>();

GalleryCriteria gallery = criteria.getGallery();
if (Validator.isNotNull(gallery)) {
    Long galleryId = gallery.getId();
    Predicate predicate = builder.equal(root.<Gallery>get(Photo_.gallery), galleryId);
    predicateList.add(predicate);
}

Predicate predicate = builder.equal(root.<String>get(Photo_.deleted), "ACTIVE");
predicateList.add(predicate);

criteriaQuery.select(root);
criteriaQuery.where(builder.and(predicateList.toArray(new Predicate[predicateList.size()])));
Query query = entityManager.createQuery(criteriaQuery);
query.setFirstResult(criteria.getFirstResult());
query.setMaxResults(criteria.getMaxResults());

List<Photo> photos = (PHOTO) query.getResultList();

我的查询是： select 将照片中的 generatedAlias0 区分为 generatedAlias0，其中 ( generatedAlias0.gallery=5L ) 和 ( generatedAlias0.deleted=:param0 ).

但我收到 ERROR: Invalid operation for forward only resultset : absolute 错误。谢谢

堆栈跟踪是：

Answer 1

我终于明白问题了，我们的前端开发人员没有在条件中设置 first 和 max result。两者的默认值为 -1。

if ( criteria.getFirstResult() == -1 ) {
    criteria.setFirstResult(0);
}

if ( criteria.getMaxResults() == -1 ) {
    criteria.setMaxResults(10);
}
