Last packet sent to the server was 0 ms ago服务器报错
来源:互联网 发布:淘宝宝贝下载软件 编辑:程序博客网 时间:2024/05/29 16:23
我使用SSH做服务器开发,头一天一切运行OK,第二天早上,我再去连接服务器,服务器这边就报如下的错误
问题原因出在:
如果连接闲置8小时 (8小时内没有进行数据库操作), mysql就会自动断开连接, 要重启tomcat
mysql默认为8小时后自动消除空闲连接,而hibernate默认空连接超时时间大于这个数。
解决办法:
修改mysql的链接失效时间,找到mysql的my.ini文件.打开后在其底部添加如下:
[mysqld]
wait_timeout=31536000
interactive_timeout=31536000
