使用一个表/实体的查询结果查询另一个实体/表

Question

我有两个表，由两个实体表示：

        @Entity
    public class HostEntity
    {
        @NotNull
        private String myGroup;

        @Id
        @NotNull
        private String host;

        @NotNull
        private long inGroupSince;
}

和

    @Entity
    public class GroupEntity
    {
        @NotNull
        private String groupId;

        @Id
        @NotNull
        private String propertiesStr;
}

我为每个实体/表都有crudRepository 。

因此，给定两个数字startTime和finishTime ，以及两个字符串stringA和stringB首先-获取所有HostEntity.myGroup（以下称此ListA ），使HostEntity.inGroupSince在startTime和finishTine之间，然后返回所有GroupEntity.groupId该GroupEntity.groupdId在ListA和GroupEntity.propertiesStr中包含stringA和StringB

实现这一目标的最佳方法是什么？ 我可以在一个查询中做到吗？

我使用crudRepository在Spring Boot中工作，这是一个新手。

我可以在repostiroy中使用@query批注，例如，我得到了以下代码：

@Repository
@Profile(Constants.SPRING_PROFILE_DEVELOPMENT)
public interface IGroupsRepositoryDev extends IGroupsRepository
{
    @Query("SELECT j FROM GroupEntity j WHERE LOWER(j.propertiesStr) LIKE %?1%  and LOWER(j.propertiesStr) LIKE %?2% and LOWER(j.propertiesStr) LIKE %?3%"
        + " and LOWER(j.propertiesStr) LIKE %?4% and LOWER(j.propertiesStr) LIKE %?5% and LOWER(j.propertiesStr) LIKE %?6% and LOWER(j.propertiesStr) LIKE %?7%"
        + " and LOWER(j.propertiesStr) LIKE %?8% and LOWER(j.propertiesStr) LIKE %?9% and LOWER(j.propertiesStr) LIKE %?10% and LOWER(j.propertiesStr) LIKE %?11% ")
    List<UUID> findByProperties(String property1,String property2,String property3,String property4,String property5,String property6
        ,String property7,String property8,String property9,String property10,String property11);

}

返回每个GroupEntity，以便GroupEntity.propertiesStr在其中包含11个字符串

UPDATE

我按照以下建议使用以下内容：

    @Query(" SELECT groupId from GroupEntity where groupId IN (SELECT myGroup FROM HostEntity WHERE inGroupSince > ?12 AND inGroupSince < ?13) "
       + "AND LOWER(propertiesStr) LIKE %?1%  and LOWER(propertiesStr) LIKE %?2% and LOWER(propertiesStr) LIKE %?3%"
       + " and LOWER(propertiesStr) LIKE %?4% and LOWER(propertiesStr) LIKE %?5% and LOWER(propertiesStr) LIKE %?6% and LOWER(propertiesStr) LIKE %?7%"
       + " and LOWER(propertiesStr) LIKE %?8% and LOWER(propertiesStr) LIKE %?9% and LOWER(propertiesStr) LIKE %?10% and LOWER(propertiesStr) LIKE %?11% ")
   List<String> findByPropertiesBetweenTime(String property1,String property2,String property3,String property4,String property5,String property6
       ,String property7,String property8,String property9,String property10,String property11,long st,long ft);

我把它放到GroupEntity仓库中，但是不起作用。 我究竟做错了什么 ？

Answer 1

[...]获取所有HostEntity.myGroup（我们称其为ListA），使得HostEntity.inGroupSince在startTime和finishTine之间[...]

SELECT myGroup FROM HostEntity WHERE inGroupSince > startTime AND inGroupSince < finishTime

[...]然后，返回所有GroupEntity.groupId，以使GroupEntity.groupdId位于ListA中。[...]

使用上面的SELECT作为内部选择：

SELECT groupId FROM GroupEntity 
WHERE 
  groupId IN (SELECT myGroup FROM HostEntity WHERE inGroupSince > startTime AND inGroupSince < finishTime)

[...]和GroupEntity.propertiesStr包含stringA和StringB [...]

添加喜欢：

SELECT groupId FROM GroupEntity 
WHERE 
  groupId IN (SELECT myGroup FROM HostEntity WHERE inGroupSince > startTime AND inGroupSince < finishTime)
AND propertiesStr LIKE '%stringA%' 
AND propertiesStr LIKE '%stringB%'

好吧！ 得到它的工作！

使用以下查询：

@Query("select ge from GroupEntity ge where ge.groupId in ( select k.myGroup from HostEntity k where k.inGroupSince > ?1 and k.inGroupSince < ?2 ) "
       + "and ge.propertiesStr like %?3% and ge.propertiesStr like %?4% and ge.propertiesStr like %?5% and ge.propertiesStr like %?6% and ge.propertiesStr like %?7% "
       + "and ge.propertiesStr like %?8% and ge.propertiesStr like %?9% and ge.propertiesStr like %?10% and ge.propertiesStr like %?11% and ge.propertiesStr like %?12% "
       + " and ge.propertiesStr like %?13%")
    List<GroupEntity> findGrpWithPropertiesBetweenTime(long st,long ft,String property1,String property2,String property3,String property4,String property5,String property6
       ,String property7,String property8,String property9,String property10,String property11);
