我有一个cronjob，需要通过condition子句从db获取一些项。在这种情况下，我需要比较一些日期的时间，它们就像数据库中的（fri-dec 18 12:36:07 eet 2020）（java.util.date）。当执行查询时，我需要从数据库中检索到比当前时间早1小时的项。
我想我的问题应该是 select * from table_name where date_column > int_variable. 问题是变量是一个从别处设置的整数。我该怎么做？我需要把变量从int改成别的吗？我以我的班级为例。在我的课堂上，我还没有上面写的示例查询。谢谢！

    final int maxJobTime = httpSessionCleanJobModel.getTime();

    final String queryString = "SELECT {" + StoredHttpSessionModel.PK + "} FROM {" + StoredHttpSessionModel._TYPECODE + "}";

    final Date specificTime = new Date();
    final FlexibleSearchQuery query = new FlexibleSearchQuery(queryString, Collections.singletonMap("specificTime", specificTime));

    final SearchResult<StoredHttpSessionModel> searchResult = flexibleSearchService.search(query);

    List<StoredHttpSessionModel> assetModelList = searchResult.getResult();

    for(StoredHttpSessionModel storedHttpSessionModel : assetModelList) {
        LOG.info(storedHttpSessionModel.getModifiedtime());
    }

    LOG.info("Finished cleaning StoredHttpSession items...");
    return new PerformResult(CronJobResult.SUCCESS, CronJobStatus.FINISHED);
}
