------解决方案--------------------------------------------------------


Hibernate配置有问题吧
------解决方案--------------------------------------------------------
上述问题是由mysql5数据库的配置引起的。mysql5将其连接的等待时间(wait_timeout)缺省为8小时。如果在wait_timeout秒期间内,An internal error occurred during数据库连接(java.sql.Connection)一直处于等待状态,mysql5就将该连接关闭。这时,你的Java应用的连接池仍然合法地持有该连接的引用。当用该连接来进行数据库操作时,就碰到上述错误。
查看mysql5的手册,发现对wait_timeout的最大值分别是24天/365天(windows/linux)。以windows为 例,假设我们要将其设为21天,我们只要修改mysql5的配置文件“my.ini”(mysql5 installation dir),增加一行:wait_timeout=1814400,重新启动mysql5即可。
------解决方案--------------------------------------------------------
是一直连接不上,还是过一段时间就连接不上?如果是过一段时间连接不上的话,就像楼上说的,应该是mysql配置的问题。
------解决方案--------------------------------------------------------
数据连接池配置有错误!java.lang.NullPointerException
------解决方案--------------------------------------------------------
