问题1：No exception of type HibernateException can be thrown; an exception type must be a subclass of Throwable

解决方法：导入javaee-api-7.0.jar包 (jar包获取地址放在最下面了)

问题2：The server time zone value ‘�й���׼ʱ��’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the ‘serverTimezone’ configuration property) to use a more specifc time zone value if you want to utilize time zone support.

翻译：

解决方法：错误是因为时区导致的，我们可以在连接数据库时指定时区

指定时区为上海
格式：jdbc:mysql:///hibernate?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
