java ee好像因为用iBATIS框架抛错

[jackjack123123123]

我用的是struts2+iBATIS+spring搭建的系统。经常抛出一个Could not load com.mysql.jdbc.profiler.ProfilerEventHandlerFactory. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.
信息: Illegal access: this web application instance has been stopped already. Could not load com.mysql.jdbc.profiler.ProfilerEventHandlerFactory. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

我的iBATIS是这样写的：
