使用mysql  和hibernate 3.2开发的一个小型网站，上传到服务器上，第一天还能够正常访问，第二天一早就出现了异常，异常如下：

原因分析：Mysql服务器默认的“wait_timeout”是8小时，也就是说一个connection空闲超过8个小时，Mysql将自动断开该 connection。这样就出现了上面这个问题。java.net.SocketException: Software caused connection abort: socket write error。网上的解决方法有几种，我选用第一种：在mysql安装目录下找到my.ini文件中添加超时限制：在该文件最后添加一行：wait_timeout=2880000。这样把之前的超时限制把8小时（28800）扩大为800小时。这样重启了mysql后再在其中输入命令：show global variables like "wait_timeout";查看超时是否已修改为：2880000。重启tomcat(如果已启动)，OK。

这不是很好的解决办法，最好是使用连接池技术

是的.连接池的定时检查连接可以避免mysql长时间无使用.
再想想,对于这样不常访问的应用再用个连接池,也真是浪费.
