https://developer.aliyun.com/profile/5yerqm5bn5yqg?spm=a2c6h.12873639.0.0.6eae304abcjaIB检查一下是否有没有关闭的Connection对象，搜索代码中的getConnection()语句回复<aclass='referer'target='_blank'>@始终888:这种用法是jfinal自己关的连接，如果是DbKit.getConnection()则需要楼主自己关回复<aclass='referer'target='_blank'>@JFinal://用户登录Usersuser=Users.dao.findFirst("select*fromuserswhereuserid=?anduserpwd=?",userid,userpwd);你看我这样写的对吗?jfinal打开的连接会自动关毕，如果是你自己打开的就要自己关了我用的是jfinalc3p0Plugin数据库连接插件,不是自动关闭的connection吗,在那里写呢?数据库连接池的问题<atarget='_blank'>@始终888调整c3p0参数看下db端的设置确实是这个问题我现在用druid不用c3p0了,不过该怎么解决这个报错呢?
