我想更新的MyBatis的春季MySQL的一个记录，我更新一个接一个，下面是MyBatis的配置： 更新的建议设置数=＃{数}，版本=＃{版本}，频率=＃{频率}其中id =＃{ID}
和服务代码：
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.");
}
任何人都可以HEL我呢？非常感谢。
看起来像MySQL服务器停止响应。它总是发生在同一个地方吗？ MySQL服务器日志说什么？那里有任何错误消息？ – 2012-03-02 03:58:45
Jim Garrison，当连接建立时，我通过add useCompression = true修复了它。非常感谢。 – Leo 2013-06-03 01:06:55
