有人能看出我做错了什么吗？两个表中都有一个已删除的列，但链接表中没有。

为了调试它，激活Hibernate日志记录是原始的。
请参阅本帖：

当我尝试列出所有类似以下内容的文章时，请参见hibernate日志中出现的内容：

为了理解这种行为，我将使用
this.ormSettings.saveMapping=true

以下是文件：

这种方法有效，但不利于代码维护和可读性。

如果有人有更好的解决方案，我很感兴趣。
到目前为止，我找到的唯一解决方法是使用
orExecuteQuery（）重写getter
。在那里，我可以直接查询对象并查找这样的内容。就我个人而言，我更喜欢使用cfscript，因此我的代码如下所示：

                                   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class entity-name="Tag" lazy="true"
        name="cfc:www.app.models.test.Tag" table="tag">

            <column length="255" name="id"/>
        </id>
        <property name="name" type="string">
            <column name="name"/>
        </property>
        <property name="deleted" type="string">
            <column default="0" name="deleted"/>
        </property>
        <bag name="articles" table="link_article_tag">
            <key column="tagId"/>
            <many-to-many class="cfc:www.app.models.test.Article" column="articleId"/>
        </bag>
    </class>
</hibernate-mapping>



    <bag name="tags" table="link_article_tag">
        <key column="articleId"/>
        <many-to-many class="cfc:www.app.models.test.Tag" column="tagId" where=" deleted = 0 "/>
    </bag>



public array function getSettings() {
    return ORMExecuteQuery("SELECT s FROM template t JOIN t.settings s WHERE t.id=:id AND s.deleted=:deleted", {
        deleted=false, id=this.getId()
    });
}

另外，不要忘记多对多属性上的
singularName
属性

与此相关的是，我在两个对象上都遇到了使用属性的问题。在这种情况下，您实际上只需要在模板对象上使用它们。这样想：模板需要知道它的设置，但设置不需要知道它们所属的模板——以这种方式在两个对象上使用属性在某些情况下可能会导致错误。
不知道你在那篇文章的后半部分说了些什么。但是我把where子句换成了“settings\u 1\u.deleted='false'”，这是一种攻击。但这是有效的。如何为sql生成别名？我能指望它不会改变吗？事实上，在这种情况下，管理Hibernate映射看起来非常糟糕。我也遇到过同样的问题，但也无法解决。因此，问题在于where子句查询的是链接表，而不是其他对象表。那么我们如何解决这个问题呢？
