Question

我使用序数参数和IN子句遇到了命名查询的问题。

这是我的命名查询：

@NamedQuery(name = "Photo.getByIds", query = "FROM Photo i WHERE i.User.idUser = ?1 AND i.idPhoto IN ?2")

这是获取照片列表的代码：

TypedQuery<Photo> q = entityManager.createNamedQuery("Photo.getByIds", Photo.class);

q.setParameter(1, 50);
q.setParameter(2, Arrays.asList(50, 51));

List<Photo> photoList = q.getResultList();

这就是我一直得到的错误：

org.hibernate.QueryException: Named parameter does not appear in Query: 1 [FROM entity.Photo i WHERE i.User.idUser = ?1 AND i.idPhoto IN (:x20_, :x21_)] <java.lang.IllegalArgumentException: org.hibernate.QueryException: Named parameter does not appear in Query: 1 [FROM entity.Photo i WHERE i.User.idUser = ?1 AND i.idPhoto IN (:x20_, :x21_)]>java.lang.IllegalArgumentException: org.hibernate.QueryException: Named parameter does not appear in Query: 1 [FROM br.gov.sus.cadsus.entity.CadsusImagemFoto i WHERE i.cadsusFotografia.coSeqFotografia = ?1 AND i.coSeqImagem IN (:x20_, :x21_)]

出了什么问题？我检查了这些方法/函数/ jpql的语法，一切似乎都没问题。我也尝试使用命名参数，它工作。但这对我来说不是一个解决方案。我需要使用序数参数。

有人有线索吗？

缺少选择。查询应该是

@NamedQuery(name = "Photo.getByIds", query = "SELECT i FROM Photo i WHERE i.User.idUser = ?1 AND i.idPhoto IN ?2")

带有其他参数的JPQL IN子句，使用序数参数
