Hibernate 无法使用 Postgres 在 jpql 中定义空参数

【中文标题】Hibernate 无法使用 Postgres 在 jpql 中定义空参数【英文标题】：Hibernate can't define null parameters in jpql with Postgres 【发布时间】：2021-06-28 08:27:46 【问题描述】：

我在 Spring Data 存储库中创建了一些方法。这个想法是让每个参数都是可选的（或可为空的）。

 @Query("SELECT lp FROM LicensePlatformEntity lp WHERE " +
        "(:ownerId is null or lp.ownerCompanyId = :ownerId) AND " +
        "(:assignedCompanyId is null or lp.assignedCompanyId = :assignedCompanyId) AND " +
        "(:assignedUserId is null or lp.assignedUser.id = :assignedUserId) AND " +
        "(:isAssigned is null or lp.assignedCompanyAcceptedLicense = :isAssigned)")
List<LicensePlatformEntity> findAllByFollowing(UUID ownerId, UUID assignedCompanyId, UUID assignedUserId, Boolean isAssigned);

它在内存数据库中的 H2 上运行良好，但 PostgreSQL 抛出异常，并声称它无法定义参数 %1 或任何其他以空值传递的参数。下一步是应用分页，所以目前它适用于CriteriaBuilder，但它没有很好的分页解决方案，不是基于偏移限制。

如何使用开箱即用的分页解决方案使可选参数搜索适合 PostgreSQL，它不是冗长的可扩展和基于 Spring 堆栈的？感谢任何帮助！

有一些尝试将参数显式转换为休眠类型，使用完整的类型引用，这看起来很糟糕。而且还破坏了 Intellij 查询处理，这不是没用的东西。

这个JPA Query to handle NULL parameter value 没有任何有用的信息。请在声明重复之前三思。

【问题讨论】：

这能回答你的问题吗？ Spring Data query could not determine data type of UUID parameter 还可以查看 spring data jpa specifications。你可以看一个例子here 【参考方案1】：

您可以通过两种方式做到这一点：

考虑所有极端情况，编写 16 种可能的方法。使用如下规范：

你可以参考我的规范（我知道它完全不同）

    public static Specification<Post> search(String keyword) 
        return ((root, criteriaQuery, criteriaBuilder) -> 
            criteriaQuery.distinct(true);
            if (keyword == null) 
                return null;
            
            return criteriaBuilder.or(
                    criteriaBuilder.like(root.get("title"), "%" + keyword + "%"),
                    criteriaBuilder.like(root.get("content"), "%" + keyword + "%"),
                    criteriaBuilder.like(root.get("excerpt"), "%" + keyword + "%"),
                    criteriaBuilder.equal(root.join("author").get("name"), keyword),
                    criteriaBuilder.equal(root.join("tags").get("name"), keyword.trim().toUpperCase())
            );
        );
    

     public Page<Post> findAllPostWithFilters(int pageNo, int pageSize, String sortField, String order,
                                             String keyword, List<Long> tids, List<Long> uids,
                                             Date starDate, Date endDate) 
        return postRepository.findAll(PostSpecification.search(keyword)
                        .and(PostSpecification.filterPostByTagIdList(tids))
                        .and(PostSpecification.filterPostByAuthorIdList(uids))
                        .and(PostSpecification.filterPostAfter(starDate))
                        .and(PostSpecification.filterPostBefore(endDate)),
                PostSpecification.getPageable(pageNo, pageSize, sortField, order));
