Question

我一直在更新应用程序中的库并添加新功能我从Hibernate 3迁移到4，我不得不对xml进行一些调整，ImprovedNamingStrategy停止工作。

我确定下面的配置存在问题：

虽然数据库上有一个名为document_history的列，但应用程序正在创建一个名为documentHistory的新列

即使是创建新列的事实也是错误的。

<prop key="hibernate.hbm2ddl.auto">validate</prop>

解决问题的两件事属性名称错误，必须是jpaPropertyMap 和hibernate.ejb.naming_strategy错过了ejb

<property name="**jpaPropertyMap**">
  <props>
    <prop key="hibernate.show_sql">true</prop>
    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
    <prop key="hibernate.hbm2ddl.auto">validate</prop>
    <prop key="hibernate.**ejb**.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>
  </props>
</property>
