spring jpa update更新数据不生效

遇到springjpa 有时候更新数据成功，有时候又失败了，还是要开启清空缓存和将更新强制刷入数据库

@Modifying(
        clearAutomatically = true,  // 清空EntityManager缓存，避免读旧数据
        flushAutomatically = true   // 强制将更新刷入数据库（关键！解决“执行了但没刷库”）
)
@Transactional
@Query(nativeQuery = true, value =
        "UPDATE crowd_special_detail SET placement_where_cond = :placementWhereCond, placement_udaf_cond = :placementUdafCond " +
                "WHERE crowd_id = :crowdId AND id_type = :idType"
)
Integer updatePlacementWhereCondAndUdafCond(
        @Param("crowdId") Integer crowdId,
        @Param("idType") String idType,
        @Param("placementWhereCond") String placementWhereCond,
        @Param("placementUdafCond") String placementUdafCond
);
