Java 休眠来自DB的hbm和POJO'；不能生成外键名称

我是hibernate的新手，我使用Netbeans示例项目生成了POJO表单数据库。所有这些似乎都正常工作，但是在hbn和java文件中没有外键名，这是一个问题，因为我想从POJO文件开始生成模式DDL

我的hibernate.cfg.xml

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
    <property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
    <property name="hibernate.connection.url">jdbc:oracle:thin:@server1:1521:orcl</property>
    <property name="hibernate.connection.username">TABLE_OWN</property>
    <property name="hibernate.connection.password">password</property>
    <property name="hibernate.default_schema">TABLE_OWN</property>
  </session-factory>
</hibernate-configuration>  

由hibernate生成的hbm文件

谢谢

您需要用外键指定列名还是约束名称？costraints的名称。在文件hbm中，我有外键的定义，但没有关于名称的信息，请参见多对一标记的示例，

alter table users\u roles add constraint some\u constraint\u name外键（role\u id）引用spring\u roles（f\u id）

您需要能够指定

某些约束\u名称

？请将所有示例添加到问题中，而不是添加到注释中。发布更新了更多详细信息您是否需要指定带有外键的列名或约束名称？costraints的名称。在文件hbm中，我有外键的定义，但没有关于名称的信息，请参见多对一标记的示例，
