以下是我的映射

    <description xmlns="">Default mapping for class
        GhraPayOrderRequest
    </description>
    <map-to xml="root" ns-prefix="diffgr"
        ns-uri="urn:schemas-microsoft-com:xml-diffgram-v1" />
    <field name="fromCities" type="pkg.FromCity" collection="arraylist">
        <bind-xml name="root:FromCity" node="element"
            xmlns:root="urn:schemas-microsoft-com:xml-diffgram-v1" />
    </field>

</class>

        ns-uri="urn:schemas-microsoft-com:xml-diffgram-v1" />

    <field name="stateId" type="java.lang.String">

            xmlns:FromCity="urn:schemas-microsoft-com:xml-diffgram-v1" />
    </field>
</class>

但我收到了以下错误

org.springframework.oxm.UnmarshallingFailureException: Castor unmarshalling exception; nested exception is org.exolab.castor.xml.MarshalException: The namespace associated with the prefix 'diffgr' could not be resolved.

请帮我解决这个问题

Answer 1

这个XML最多是奇怪的...你是否尝试过将名称空间声明移动到根元素，如下所示：

<root xmlns="urn:schemas-microsoft-com:xml-diffgram-v1" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
    <FromCity diffgr:id="FromCity1" msdata:rowOrder="0">
        <StateID>1073</StateID>
        <State>Ahmedabad</State>
    </FromCity>
</root>

实际上，您甚至不需要额外的diffgr命名空间，因为它的URN与默认命名空间的{{1}}相同。或者这是你的XML中的错误吗？

Answer 2

您需要在根标记中指定命名空间模式：

<root xmlns:sql="urn:schemas-microsoft-com:xml-sql" sql:mapping-schema="DiffGramSchema.xml">

有关XML的示例，请参阅DiffGram Examples。

与前缀＆＃39; diffgr＆＃39;相关联的命名空间。无法解决。蓖麻
