如何在不删除引用对象的情况下删除Nhibernate多对多关联

大家好

<property name="Name" column="[SiteGroupName]"/>

<many-to-one name="ClientInfo" column="[ClientID]"/>

<set name="internalSites" table="SiteGroupSites" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="Site" column="SiteID"/>
</set>

<set name="internalSiteGroups" table="SiteGroupGroups" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="SiteGroup" column="ChildSiteGroupID"/>
</set>

如果不删除NHibernate中的对象，我在删除两个对象之间的关联时遇到问题。我的映射文件：

<?xml version="1.0" encoding="utf-8" ?>

<property name="Name" column="[SiteGroupName]"/>

<many-to-one name="ClientInfo" column="[ClientID]"/>

<set name="internalSites" table="SiteGroupSites" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="Site" column="SiteID"/>
</set>

<set name="internalSiteGroups" table="SiteGroupGroups" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="SiteGroup" column="ChildSiteGroupID"/>
</set>

我不明白的是，当我保存时，它会删除关联和实际站点。我是不是误解了什么？我想要的是网站从网站组中删除，而不是完全删除

<property name="Name" column="[SiteGroupName]"/>

<many-to-one name="ClientInfo" column="[ClientID]"/>

<set name="internalSites" table="SiteGroupSites" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="Site" column="SiteID"/>
</set>

<set name="internalSiteGroups" table="SiteGroupGroups" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="SiteGroup" column="ChildSiteGroupID"/>
</set>

我们将非常感谢您的帮助。

您觉得如何

<property name="Name" column="[SiteGroupName]"/>

<many-to-one name="ClientInfo" column="[ClientID]"/>

<set name="internalSites" table="SiteGroupSites" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="Site" column="SiteID"/>
</set>

<set name="internalSiteGroups" table="SiteGroupGroups" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="SiteGroup" column="ChildSiteGroupID"/>
</set>

site.Sitegroup=null；

//保存

你解决问题了吗？

<property name="Name" column="[SiteGroupName]"/>

<many-to-one name="ClientInfo" column="[ClientID]"/>

<set name="internalSites" table="SiteGroupSites" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="Site" column="SiteID"/>
</set>

<set name="internalSiteGroups" table="SiteGroupGroups" cascade="none" inverse="true">
  <key column="[SiteGroupID]"/>
  <many-to-many class="SiteGroup" column="ChildSiteGroupID"/>
