元素类型的内容“加入”必须再选择匹配“（，评论，钥匙，（财产？|？多到一个|成分|

我知道有下文，但我这个XML文件非常愚蠢的错误无法修复一样。我使用与Hibernate混合策略，我想只有一个子类作为表的策略，其余为joined.Here是XML。我知道这应该是愚蠢的，但我不是在XML映射我使用注释而我现在用XML HBMS结识元素类型的内容“加入”必须再选择匹配“（，评论，钥匙，（财产？|？多到一个|成分|

例外是这样的：

尝试指定的<key column=" "/>与column="PAYMENT_ID"如下：

<hibernate-mapping> 
    <class table="PAYMENT" name="parent.Payment"> 
     <id name="id" type="long" column="PAYMENT_ID"> 
      <generator class="native" /> 
     </id> 
     <discriminator column="PAYMENT_TYPE" type="string"/> 
     <property name="amount" column="AMOUNT"/> 
     <subclass discriminator-value="CREDIT" 
     name="child.CreditCardPayment"> 
      <join table="CREDIT_PAYMENT"> 
       <key column="PAYMENT_ID"/> 
       <property name="creditCardType" column="CCTYPE" type="string"/> 
      </join> 
     </subclass> 
     <subclass name="child.CashPayment" discriminator-value="CASH"> 
      <join table="CASH_PAYMENT"> 
       <key column="PAYMENT_ID"/> 
       <property name="cashType" column="CATYPE" type="string"/> 
      </join> 
     </subclass> 
     <subclass name="child.ChequePayment" discriminator-value="CHEQUE">

</hibernate-mapping>
