sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl不能转换为java.lang.Class

Question

当我在通配符中部署war文件时，我会得到以下错误；有线索吗？

Hibernate version=5.0.1.Final

Hibernate验证器版本=5.2.1

Wildfly 9包含的hibernate版本不是5，请参见What versions of libraries are shipped with WildFly 9.0.1.Final，您可能必须使用正确的版本，或者使用jboss-deployment-structure.xml排除服务器库。或者试试野蝇10，其中包括hibernate 5。
