为Hibernate Session Factory创建sessionFactory时出现Sprin

在Spring MVC配置文件中为hibernate创建sessionFactory时，出现以下错误。

我得到的错误是：

在上下文初始化期间遇到-取消刷新尝试：org.springframework.beans.factory.BeanCreationException：在ServletContext资源[/WEB-INF/spring-mvc-crud-demo-servlet.xml]中创建名称为'sessionFactory'的bean时出错：调用init方法失败；嵌套异常是java.lang.NoClassDefFoundError：net / bytebuddy / NamingStrategy $ SuffixingRandom $ BaseNameResolver 2019年11月29日PM org.springframework.web.servlet.FrameworkServlet initServletBean严重：上下文初始化失败org.springframework.beans.factory .BeanCreationException：创建在ServletContext资源[/WEB-INF/spring-mvc-crud-demo-servlet.xml]中定义的名称为'sessionFactory'的bean时出错：调用init方法失败；嵌套的异常是java.lang.NoClassDefFoundError：

我的Spring配置文件如下：
