刚学Hibernate框架，代码照书上敲的，书上用的Hibernate5.2.7

依赖库已添加：

mysql驱动jar包放在了WebContent/WEB-INF/lib下

进行数据库相关操作时出现ClassNotFound异常

java.lang.ClassNotFoundException: org.hibernate.Query

错误信息为：

严重: Servlet.service() for servlet [StudentServlet] in context with path [/UseHibernate] threw exception [Servlet execution threw an exception] with root cause

java.lang.ClassNotFoundException: org.hibernate.Query

hibernate.cfg.xml文件内容如下：

1 <?xml version="1.0" encoding="UTF-8"?>
