我想通过mybatis和spring更新mysql中的一条记录，然后一个接一个地更新它，下面是mybatis config：更新建议集count =＃{count}，version =＃{version}，freq =＃{freq}其中id =＃{id}

以及服务代码：

for(RelationBvo relation : list){

       Long totalCount = solrDealService.queryResult(relation.getWord(),null,null,0);

       relation.setCount(totalCount.intValue());

       if(relation.getFreq() == 0){
            relation.setFreq(1);
       }

       ***relationDao.updateSuggest(relation);//update record***

       executedCount++;

       logger.info("Program have executed "+executedCount+" records.");
}

有人可以帮我吗？非常感谢。
