java.lang.reflect.InvocationTargetException（在配置hibernate使用proxool连接池时报此异常解决方法）
异常：

java.lang.reflect.InvocationTargetExceptionat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at org.logicalcobwebs.proxool.ShutdownHook.remove(ShutdownHook.java:40)at org.logicalcobwebs.proxool.ProxoolFacade.shutdown(ProxoolFacade.java:238)at org.logicalcobwebs.proxool.ProxoolFacade.shutdown(ProxoolFacade.java:220)at org.logicalcobwebs.proxool.ShutdownHook.run(ShutdownHook.java:99)at java.lang.Thread.run(Unknown Source)Caused by: java.lang.IllegalStateException: Shutdown in progressat java.lang.Shutdown.remove(Unknown Source)at java.lang.Runtime.removeShutdownHook(Unknown Source)... 9 more

解决方法：
在session关闭的时候后面加上org.logicalcobwebs.proxool.ProxoolFacade包的ProxoolFacade.shutdown(1);方可解决。
