[com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.在一个老项目的交接过程中，出现了这个问题，刚开始一直奔着是内存泄漏，jdbc驱动实例无法销毁（因为项目里面有定时任务，显示的调用了sqlsessionfactory，但是是mybaitis项目）的原因。后来才发觉是，jdbc的驱动的ip不对，给的是错误的，更换了之后就OK了。这就是一次明显的XY问题。
