java - 如何通过jaxb bindings.xml区分重复元素

Question

我必须处理 xsd 模式才能通过 jaxb 生成 java 代码，并且其中一个序列中有两个具有相同名称的元素。这引起了麻烦，我开始使用 Bindings.xml 来区分这两个元素。

我的问题是，我无法为此目的精确定位一个元素，它的目标是我想要的元素加上另一个 compleType 中的另一个元素。

这是我的绑定(bind).xml

<jxb:bindings version="2.0"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
    <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
        <jxb:bindings node=".//xsd:attribute[@name='value']">
            <jxb:property name="requiredValue"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>
<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']">
        <jxb:bindings multiple="true" node="//xs:element[2]">
            <jxb:property name="delimiter1"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

因此，第一个 delimiter 元素正确重命名为 delimiter1，但 schemaVersion 元素也重命名为 delimiter1!

对哪里出了问题有什么建议吗？

按照我的 bindings.xml 的建议使用 @ref 后，如下所示:

<jxb:bindings version="2.0"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
        <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
            <jxb:bindings node=".//xsd:attribute[@name='value']">
                <jxb:property name="requiredValue"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
    <jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
        <jxb:bindings node="//xs:complexType[@name='FileType']">
            <jxb:bindings multiple="true" node="//xs:element[@ref='sv:delimiter'][1]">
                <jxb:property name="delimiter1"/>
            </jxb:bindings> 
            <jxb:bindings node="//xs:element[@ref='sv:delimiter'][2]">
                <jxb:property name="delimiter2"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

现在，它会重命名所有出现的 sv:delimiter(文档中的 3)，而不是仅重命名 FileType 复杂类型中的那些。它比以前更好，但我希望能够只重命名选定的元素，而不是全部(如果可能的话)。

感谢 Xstian，这是有效的解决方案:

<jxb:bindings version="2.0"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
        <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
            <jxb:bindings node=".//xsd:attribute[@name='value']">
                <jxb:property name="requiredValue"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
    <jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
            <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='sv:delimiter'][1]">
                <jxb:property name="delimiter1"/>
            </jxb:bindings> 
            <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='sv:delimiter'][2]">
                <jxb:property name="delimiter2"/>
            </jxb:bindings> 
    </jxb:bindings>
</jxb:bindings>

谢谢

尝试使用示例

<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']">
        <jxb:bindings node="//xs:element[@ref='mbms2012:Alternate-Content-Location-1']">
            <jxb:property name="delimiter1"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

或

<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='mbms2012:Alternate-Content-Location-1']">
          <jxb:property name="delimiter1"/>
    </jxb:bindings>
</jxb:bindings>
