java - spring data jpa 和多个集合的条件

Question

我想传递一个列表，其中所有内容都应该匹配。

  @Query("select g.name as name FROM Gym  g  " +
            "LEFT JOIN g.listOfEquipment   listOfEquipment  " +
            "WHERE " +
            "(((:listOfEquipment) is null) or listOfEquipment.id in (:listOfEquipment)) "+
            "AND (((:listOfAmenity) is null) or listOfAmenity.id in (:listOfAmenity))")
  Page<Map<String, Object>> listing(@Param("listOfEquipment") Set<Integer> listOfEquipment,@Param("listOfAmenity") Set<Integer> listOfAmenity)

上面的查询适用于 OR 但我需要 AND

假设我正在传递 1,2,3 那么结果应该是所有拥有设备 1 and 2 and 3 的 gym 设施也一样

我试过了 Finding items with a set containing all elements of a given set with jpql

但它对我没有帮助，因为有多个过滤器

网址是

http://localhost:8080/filter?listOfEquipment=5,3&listOfAmenity=51,13&sort=name

Answer 1

假设列表不包含重复项，此查询应为您提供匹配所有 listOfEquipment 的 Gym.id。

select g.id as name 
FROM Gym  g 
LEFT JOIN g.listOfEquipment listOfEquipment
WHERE listOfEquipment.id in (:listOfEquipment)) 
GROUP BY g.id
HAVING count(g.id) = #{#listOfEquipment.size}    

您可以将它和类似的 listOfAmenity 查询用作主查询中的子选择。

select g.name as name 
FROM Gym  g 
LEFT JOIN g.listOfEquipment listOfEquipment 
WHERE (((:listOfEquipment) is null) 
    OR g.id in (
    select g.id as name 
    FROM Gym  g 
    LEFT JOIN g.listOfEquipment listOfEquipment
    WHERE listOfEquipment.id in (:listOfEquipment)) 
    GROUP BY g.id
    HAVING count(g.id) = #{#listOfEquipment.size}   
)) 
AND (((:listOfAmenity) is null) 
    OR g.id in (
    select g.id as name 
    FROM Gym  g 
    LEFT JOIN g.listOfAmenity listOfAmenity
    WHERE listOfAmenity.id in (:listOfAmenity)) 
    GROUP BY g.id
    HAVING count(g.id) = #{#listOfAmenity.size}   
))
