Jpa的 pageable 用法例子。

Sort sort =  Sort.by(Sort.Direction.DESC, "alarmNo")
            .by(Sort.Direction.ASC,  "reportTime");

        // 设备报警信息取得
        Pageable pageable = PageRequest.of(0, 100, sort);
        Page<DeviceAlarmHistoryQueryEntity> alarmPages = deviceAlarmHistoryQueryRepository.findAll(pageable);
