长时间不用提示错误

qbdezh

我用的推广版，长时间不访问，等到访问的时候，老是报错，把服务重启了就没事了，这个情况应该怎么弄啊

这个是长时间没有登录导致的数据库的断开，所以在tomcat的server.xml中修改数据源的配置信息即可。
在Resource中添加一个配置信息validationQuery="select sysdate from dual" 。

在长时间没有访问tomcat后，数据库连接已经失效，连接池因为没有检测，所以认为连接有效，导致连接出错。避免这种错误的方法是设置连接有效查询sql语句。设置后，连接池会使用该sql语句测试连接是否有效，如果无效，会重新建立连接。
你先试试吧，排除下错误看看效果。
