我正在尝试解组一个基本的 XML 文档，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<personnes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="personnes.xsd">
  <personne>
    <prenom>toto</prenom>
    <nom>dupont</nom>
  </personne>
  <personne>
    <prenom>titi</prenom>
    <nom>durand</nom>
  </personne>
  <personne>
    <prenom>tata</prenom>
    <nom>lanvin</nom>
  </personne>
</personnes>

对应的 XSD 在这里：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="personnes">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="personne" maxOccurs="unbounded">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="prenom" type="xs:string" />
                            <xs:element name="nom" type="xs:string" />
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

我系统地得到一个 UnmarshallingFailureException：

对于您的信息，我使用 Spring OXM。

我强烈怀疑这与我的 XSD 架构和可能的命名空间有关......

有人可以帮忙吗？

编辑：这是相关的 Spring 配置：

<bean id="personneItemReader" class="org.springframework.batch.item.xml.StaxEventItemReader">
        <property name="resource" value="classpath:personnes.xml" />
        <property name="fragmentRootElementName" value="personne" />
        <property name="unmarshaller" ref="jaxb2Marshaller" />
    </bean>

    <bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound">
            <list>
                <value>com.docapost.batch.xml.Personnes</value>
            </list>
        </property>
        <property name="schema" value="classpath:personnes.xsd" />
    </bean>

编辑 2：如果我注释掉模式验证，则异常跟踪：

personne元素和类似乎没有链接Personne。如果您生成了模型，您可以尝试更改配置以使用上下文路径吗？

<bean id="personneItemReader" class="org.springframework.batch.item.xml.StaxEventItemReader">
    <property name="resource" value="classpath:personnes.xml" />
    <property name="fragmentRootElementName" value="personnes" />
    <property name="unmarshaller" ref="jaxb2Marshaller" />
</bean>

<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="contextPath" value="ocom.docapost.batch.xml"/>
</bean>
