Hibernate问题:首页启动服务可以正常执行数据库操作,隔好几分钟之后再操作就出错了!

[bmcsy]

大概是连接断开了,换了很久没也没有找到解决办法,郁闷ing,希望有此经验的人士指点迷津.

出错信息如下:

问题肯定是数据库没有连接上.
1.连接的地址错误..你仔细检查.
2.如果你用的是服务器上的数据库,你要打开看一下.数据库是否打的开.
3.你加载时用来懒加载.然后导致session关闭.

[showtime520]

估计楼主是用了延时加载，但是Session的开与关没有控制好

[Ami121]

是不是LZ第一次操作session关闭链接后 第二次没有打开啊

看看你的日志信息吧 可能会找到原因

你是不是用的jdbc连接的啊，我用jdbc连接mysql的时候也出现了这个问题，刷新两次后就断了，后来我换成连接池了，问题就解决了，不知道什么问题。你换成连接池后看看行不行。
我那个项目是ssh做的.tomact6.0连接池和以前版本配置有区别。可以参考：http://www.java2000.net/viewthread.jsp?tid=4536

Connection reset

SetCharacterEncodingFilter文件的103行执行不下去。如果能用eclipse debug模式但不跟踪看看。
