休眠 - 接受查询中的重复
原标题:Hibernate - Accept Duplicates in Query

我有一个冬眠查询,它可以并且确实可以从遗留数据中返回重复的行。 我能否告诉冬眠接受重复的行而不必创建某种假密钥?

这就是我的hbm看起来像的:

<hibernate-mapping package="mycompany.cms.domain">

    <class name="mycompany.cms.domain.DelDeadline" table="cms.del_deadlines">
        <id column="nid"                     name="nid"/>
        <property column="deadline_type"     name="deadline_type"/>
        <property column="del_run_date"      name="del_run_date"/>
        <property column="deadline_day"      name="deadline_day"/>
        <property column="deadline_time"     name="deadline_time"/>
    </class>

    <query name="DelDeadline.getAll">
            <![CDATA[from mycompany.cms.domain.DelDeadline]]>
    </query>
</hibernate-mapping>
最佳回答

JB Nizet 说休眠需要一个独特的 ID 。 您可以将所有列都映射成一个大复合集成集解, 这样你就会得到明显的结果, 但是可以复制 nid 。
