我想用mybatis和spring在mysql中更新一条记录，然后一条一条地更新，下面是mybatis配置： 更新建议集计数=#{count}，版本=#{version}，频率=#{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.");
}

有人能帮我吗？非常感谢。

你的mySQL连接在你的连接池识别它们之前就超时了。有多种方法可以解决此问题：

增加mysql配置文件（my.ini）中的超时值

减少连接池中的空闲时间，以便在mysql关闭连接之前丢弃连接

在池配置中添加一个验证连接查询，以便池在向您提供连接之前测试每个连接，但这会严重降低系统速度

看起来MySQL服务器已停止响应。它总是发生在同一个地方吗？MySQL服务器日志是怎么说的？有错误消息吗？Jim Garrison，我已经通过连接建立时add-useCompression=true修复了它。非常感谢。
