目前使用的hibernate5.2.9版本，配置的mysql方言为：
<property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
使用的表更新策略为：
<property name="hibernate.hbm2ddl.auto">create</property>
可是每次执行都出现了以下错误：

根据提示很显然得知：这是MySQL的版本问题导致的问题。
实际上，在MySQL5.0以前，type=InnoDB是有效的SQL语句，但是自己用的是MySQL5.7版本，type=InnoDB不再有效了。
解决办法就是修改hibernate.cfg.xml中的dialect属性，将
<property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
修改为
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
再次运行，发现可以自动建表了。
