Jpa Element Collection连接返回字符串

如何解决Jpa Element Collection连接返回字符串

我试图在Story表中检索一些变量和imageList。 ImageList是String的列表。但是，当运行查询时，它给我一个字符串而不是列表。我在哪里做错了？

    @Query("select d.id,d.createdDate,d.title,d.summaryDescription,imgs  from Story d  inner join d.imageList imgs  where ( d.createdDate between :startDate AND :endDate) " )
    fun getStoryByCreatedDateAfter(startDate: zoneddatetime,endDate: zoneddatetime = zoneddatetime.Now()): List<List<Any>>?

Story类中的元素集合

        @Fetch(FetchMode.SELECT)
        @LazyCollection(LazyCollectionoption.FALSE)
        @CollectionTable(name = "STORY_IMAGES",joinColumns = [JoinColumn(name = "story_id",referencedColumnName = "id")])
        @Column(name = "IMAGES")
        var imageList: MutableList<String> = mutablelistof()
