Java Hibernate仅在Pageable=unpaged时在Spring JPA查询中复制结果

我有一个奇怪的Hibernate案例，它在JPA存储库上运行Spring Boot，根据我的可分页实例是否未分页，我会得到重复的结果

我的可分页对象是这样构造的：

Pageable pageable;
if (size > 0) {
    pageable = PageRequest.of(page, size, sort);
} else {
    pageable = Pageable.unpaged()
}

对于确实有大小的请求，因此它们被分页，我会很好地返回我的对象。对于未分页的请求，结果对象是重复的

基础查询有点复杂，有一些获取连接和性能计数查询：

@Query(value = "select etv from EventTriggerVersion etv "
        + "inner join fetch etv.eventTrigger et "
        + "left join fetch etv.eventRules rules "
        + "left join fetch rules.conditionSets conditionSets "
        + "left join fetch conditionSets.conditions conditions "
        + "left join fetch conditionSets.dayTimeConditions dayTimeConditions "
        + "left join fetch conditions.leftOperand leftOperand "
        + "left join fetch conditions.rightOperand rightOperand "
        + "left join fetch leftOperand.leftOperand leftLeftOperand "
        + "left join fetch leftOperand.rightOperand leftRightOperand "
        + "left join fetch rightOperand.leftOperand rightLeftOperand "
        + "left join fetch rightOperand.rightOperand rightRightOperand "
        + "where etv.latestVersion = true" + " and et.project.id = :projectId "
        + "and (:skipSearch = true or lower(et.name) like lower(concat('%',cast(:search as java.lang.String),'%'))) "
        + "and (cast(:changedAfter as java.util.Date) is null or etv.createdDate >= :changedAfter)",
        countQuery = "select count(etv) from EventTriggerVersion etv "
            + "inner join etv.eventTrigger et "
            + "where etv.latestVersion = true" + " and et.project.id = :projectId "
            + "and (:skipSearch = true or lower(et.name) like lower(concat('%',cast(:search as java.lang.String),'%'))) "
            + "and (cast(:changedAfter as java.util.Date) is null or etv.createdDate >= :changedAfter)"
    )
    Page<EventTriggerVersion> findLatestVersionsInProject(@Param("projectId") UUID projectId,
        @Param("skipSearch") Boolean skipSearch, @Param("search") String search, @Param("changedAfter") Date changedAfter,
        Pageable pageable);

@Query（value=“从EventTriggerVersion etv中选择etv”
+“内部联接获取etv.eventTrigger et”
+“left join fetch etv.eventRules规则”
+“left join fetch rules.ConditionSet条件集”

+其中etv.latestVersion=true“+”和et.project.id=：projectId”
+和（：skipSearch=true或更低（et.name），如更低（concat（“%”），cast（：搜索为java.lang.String），“%”）
+“and（强制转换（：changedAfter as java.util.Date）为null或etv.createdDate>=：changedAfter）”，
countQuery=“从EventTriggerVersion etv中选择计数（etv）”
+“内部联接etv.eventTrigger et”
+其中etv.latestVersion=true“+”和et.project.id=：projectId”
+和（：skipSearch=true或更低（et.name），如更低（concat（“%”），cast（：搜索为java.lang.String），“%”）
+“和（强制转换（：changedAfter as java.util.Date）为null或etv.createdDate>=：changedAfter）”
)
Page findLatestVersionsInProject（@Param（“projectId”）UUID projectId，
@Param（“skipSearch”）布尔skipSearch、@Param（“search”）字符串搜索、@Param（“changedfter”）日期changedfter、，
可寻呼（可寻呼）；

现在，我可以在查询和设置

@QueryHints（value=@QueryHint（name=HINT\u PASS\u distinct\u THROUGH，value=“false”）

中使用一个

distinct

来解决这个问题，但这对性能来说可能并不理想，我只是好奇为什么只有未分页的页面才需要这样做
