解决方案
解决方案二：
错误信息提示的很明确：Duplicatepropertymappingofpanelfoundincom.dascom.dafc.appserver.model.portal.hibernate.PanelCustomBlockImpl
解决方案三：
Exceptioninthread"main"java.lang.NullPointerExceptionatcom.dascom.dafc.appserver.hibernate.SpringHelper.loadBeanByName(SpringHelper.java:24).NullPointerException这里不是报了空指针？从这里看看
