如何使用 jaxb 绑定来修复模式中的多个组引用？

fpml 5.3 的一部分在架构中具有以下内容

  <xsd:complexType name="Price">
<xsd:annotation>
  <xsd:documentation xml:lang="en">A type describing the strike price.</xsd:documentation>
</xsd:annotation>
<xsd:sequence>
  <xsd:element name="commission" type="Commission" minOccurs="0">
    <xsd:annotation>
      <xsd:documentation xml:lang="en">This optional component specifies the commission to be charged for executing the hedge transactions.</xsd:documentation>
    </xsd:annotation>
  </xsd:element>
  <xsd:choice minOccurs="0">
    <xsd:sequence>
      <xsd:element name="determinationMethod" type="DeterminationMethod">
        <xsd:annotation>
          <xsd:documentation xml:lang="en">Specifies the method according to which an amount or a date is determined.</xsd:documentation>
        </xsd:annotation>
      </xsd:element>
      <xsd:group ref="EquityPrice.model" minOccurs="0"></xsd:group>
    </xsd:sequence>
    <xsd:element name="amountRelativeTo" type="AmountReference">
      <xsd:annotation>
        <xsd:documentation xml:lang="en">The href attribute value will be a pointer style reference to the element or component elsewhere in the document where the anchor amount is defined.</xsd:documentation>
      </xsd:annotation>
    </xsd:element>
    <xsd:group ref="EquityPrice.model"></xsd:group>
  </xsd:choice>
  <xsd:element name="cleanNetPrice" type="xsd:decimal" minOccurs="0">
    <xsd:annotation>
      <xsd:documentation xml:lang="en">The net price excluding accrued interest. The "Dirty Price" for bonds is put in the "netPrice" element, which includes accrued interest. Thus netPrice - cleanNetPrice = accruedInterest. The currency and price expression for this field are the same as those for the (dirty) netPrice.</xsd:documentation>
    </xsd:annotation>
  </xsd:element>
  <xsd:element name="quotationCharacteristics" type="QuotationCharacteristics" minOccurs="0">
    <xsd:annotation>
      <xsd:documentation>Allows information about how the price was quoted to be provided.</xsd:documentation>
    </xsd:annotation>
  </xsd:element>
</xsd:sequence>
  </xsd:complexType>

这导致

     * <p>
 * You are getting this "catch-all" property because of the following reason: 
 * The field name "GrossPrice" is used by two different parts of a schema. See: 
 * line 1361 of file:/C:/fpml-jaxb/src/main/xsd/fpml-asset-5-3.xsd
 * line 1361 of file:/C:/fpml-jaxb/src/main/xsd/fpml-asset-5-3.xsd
 * <p>

该错误具有误导性。EquityPrice.model 以此开头，第 1361 行是总价格。问题源于上面的价格复杂类型中有 2 组对 EquityPrice.model 的引用。

  <xsd:group name="EquityPrice.model">
<xsd:sequence>
  <xsd:element name="grossPrice" type="ActualPrice" minOccurs="0">
    <xsd:annotation>
      <xsd:documentation xml:lang="en">Specifies the price of the underlyer, before commissions.</xsd:documentation>
    </xsd:annotation>
  </xsd:element>

同样的事情也适用于 TradeNovationContent，它有多个对 NewTrade.model 的引用。

我也遇到了同样的问题，解决方法是启用简单绑定模式。将以下内容添加到您的外部绑定文件中。

xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
...
<jxb:globalBindings>
    <xjc:simple />
</jxb:globalBindings>

如您所见，错误是由 JAXB 处理组的方式引起的。
