hibernate 设置hbm2ddl.auto=create不能自动建表问题

今天复习ssh框架时发现hibernate不能自动创建表结构，方言设置

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect

</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format">true</prop>
<prop key="hbm2ddl.auto">create</prop>
</props>
</property>

后来发现原因是<prop key="hbm2ddl.auto">create</prop>不能识别，改为

<prop key="hibernate.hbm2ddl.auto">create</prop>即可
