JPA查询以选择“ IN”子句中的多个值

Question

我想为以下SQL语句创建一个JPA参数化查询

select * from car where (colour, speed) in (('red', 50), ('blue', 70))

此查询返回预期结果

entityManager.createQuery("from Car c where (c.colour, c.speed) in (('red', 50), ('blue', 70))", Car.class).getResultList();

如何将当前的硬编码值作为参数传递？

我想出了下面的“有效”解决方案。但是我担心不能保证所有参数对都按预期顺序传递吗？我不想得到速度为“ 50”的“蓝色”汽车。edit：已删除，因为它无法正常工作，另请参阅@Gas注释

在搜索时，我发现了一个非常相似的问题here.，也许与该问题更为吻合。

但是，我实现了一些不同。

@Query("SELECT p FROM Product p "
            + "LEFT JOIN p.categories category "
            + "WHERE UPPER(p.name) LIKE UPPER(CONCAT('%', COALESCE(:searchRequest, ''), '%')) "
            + "AND UPPER(p.description) LIKE UPPER(CONCAT('%', COALESCE(:description, ''), '%')) "
            + "AND p.price BETWEEN :priceLow AND :priceHigh "
            + "AND p.averageRating >= :averageRating "
            + "AND p.archived = :archived "
            + "AND ((category.name IN :selectedCategories) "
            + "OR (:amountOfSelectedCategories = 0 AND category IN (SELECT c FROM Category c))) "
            + "GROUP BY p "
            + "HAVING SIZE(p.categories) >= :amountOfSelectedCategories"
    )
    Page<Product> findAllBySearchModel(
            Pageable pageable,
            @Param("searchRequest") String searchRequest,
            @Param("description") String description,
            @Param("priceLow") BigDecimal priceLow,
            @Param("priceHigh") BigDecimal priceHigh,
            @Param("averageRating") double averageRating,
            @Param("archived") boolean archived,
            @Param("selectedCategories") List<String> selectedCategories,
            @Param("amountOfSelectedCategories") int amountOfSelectedCategories
    );
