在我的应用程序中，我在一个表中没有主键列。我将其视为代理键并尝试使用标记。但我遇到了异常。

**"org.hibernate.MappingException: Error reading resource:     
    com/mapping/FamilyDetails.hbm.xml"**

**Caused by: org.xml.sax.SAXParseException: 
    The content of element type "class" must match "
    (meta*,subselect?,cache?,synchronize*,comment?,
    (id|composite-id),discriminator?,natural-id?,(version|timestamp)?,
    (property|many-to-one|one-to-one|component|dynamic-
    component|properties|any|map|set|list|bag|idbag|array|
    primitive-array|query-list)*,
    ((join*,subclass*)|joined-subclass*|union-subclass*),loader?,
    sql-insert?,sql-update?,sql-delete?,filter*)".**

映射文件：-FamilyDetails.hbm.xml

<class name="com.beans.FamillyDetails" 
       table="personal_fmly_dtls" proxy="com.aims.beans.FamillyDetails">


    <natural-id>
        <property name="systemid" />
    </natural-id>
    <property name="membername" 
              type="java.lang.String" column="membername" not-null="true" />
    <property name="relation"  
              type="java.lang.String" column="relation" not-null="true" />
    <property name="dateOfBirth"  
              type="java.util.Date" column="dateofbirth" not-null="true" />

    <many-to-one name="Personal" column="pid" class="com.aims.beans.Personal"/>

</class>

请帮我。

它可能是另一个组件。组件不需要主键：

<set name="famildtlslst" table="personal_fmly_dtls">
  <key column="pid" not-null="true"/>
  <composite-element parent="Personal">
    <property name="systemid" />
    <property name="membername" not-null="true" />
    <property name="relation" not-null="true" />
    <property name="dateOfBirth" not-null="true" />
  </composite-element>
</set>

当然，这是另一种语义，但如果您对组件感到满意，那就更容易了。
