NHibernate HiLo-每个实体的新列和HiLo捕获

问题描述

我目前正在为我的班级使用hilo id生成器，但仅使用了最少的设置，例如

I'm currently using the hilo id generator for my classes but have just been using the minimal of settings eg

<class name="ClassA">
    <id name="Id" column="id" unsaved-value="0">
      <generator class="hilo" />
    </id>
...

但是我真的应该为NHibernate指定一个新列以使用foreach实体并为其提供最大lo吗?

But should I really be specifying a new column for NHibernate to use foreach entity and providing it with a max lo?

<class name="ClassA">
    <id name="Id" column="id" unsaved-value="0">
      <generator class="hilo">
        <param name="table">hibernate_unique_key</param>
        <param name="column">classA_nexthi</param>
        <param name="max_lo">20</param>
      </generator>
    </id>
...
<class name="ClassB">
    <id name="Id" column="id" unsaved-value="0">
      <generator class="hilo">
        <param name="table">hibernate_unique_key</param>
        <param name="column">classB_nexthi</param>
        <param name="max_lo">20</param>
      </generator>
    </id>
...

我还注意到，当我执行上述操作时，SchemaExport不会创建所有列-仅classB_nexthi，还有其他我在做错的事情.

Also I've noticed that when I do the above the SchemaExport will not create all the columns - only classB_next is there something else I'm doing wrong.
