[code="sql"]--- Cause: java.sql.SQLException: Couldn't perform the operation prepareCall: You can't perform any operations on this connection. It has been automatically closed by Proxool for some reason (see logs).
今天又遇到了这个问题
Couldn't perform the operation rollback: You can't perform any operations on this connection. It has been automatically closed by Proxool for some reason (see logs).

如果使用了连接池,这说明已经成功连接了数据库,但是
for some reason自动关闭了。
在proxool.xml文件增加一个属性maximum-active-time设置最大活动时间一个小时3600000
<maximum-active-time>3600000</maximum-active-time>
这是基于较大数据量的查询时,花费查询时间比较长,导致proxool设置的超时时间将session关闭,后续在使用库的时候提示报错。
更改了后不报错了,呵呵。
