mybatis와 spring에 의해 mysql의 레코드를 갱신하고 싶습니다. mybatis와 config가 하나씩 차례로 갱신합니다 :       제안 개수 업데이트 세트 = # {count}, 버전 = # {버전}, freq = # {freq} 여기서 id = # {id}

그리고 서비스 코드 :

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.");
}

아무도 도와 줄 수 있습니까? 대단히 감사합니다.
