我想通过mybatis和spring更新MysqL中的一条记录,并一一更新,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,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.
最佳答案
您的MysqL连接在连接池识别它们之前已超时.有多种解决方法：
>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关闭连接之前将其丢弃
>在您的池配置中添加一个验证连接查询,以便该池在将每个连接提供给您之前先对其进行测试,但这会严重降低系统速度.
